Shaft Collar

Types of Shaft Collars

Clamp style shaft collars

A variety of styles of shaft collars are available for your machining needs. Clamp style shaft collars offer better flexibility and hold better than set screw collars. They are best for shaft materials that are softer than a setscrew. Clamp style collars are generally easier to maneuver, as they are two-piece and are hinged along the shaft.
Clamp style shaft collars come in two-piece and one-piece designs. One-piece clamp collars are typically used for a single-piece shaft, while two-piece clamp collars are used for multiple shafts. The one-piece clamp collar provides a more uniform holding force, while two-piece clamp collars provide more clamping force and can be installed anywhere on the shaft. Both styles are available in English and metric measurements.
The holding power of Clamp style shaft collars depends on their bore size and concentricity. The fastening hardware also affects torque transmission. Forged screws are generally stronger than broached screws, and are less likely to ream out. However, you still need to make sure that the material of the collar is strong enough to withstand the recommended screw torque.
Clamp style shaft collars are available in 1215 lead-free steel with a black oxide finish and zinc plating, as well as 303 and 316 stainless steel. They are also available in 2024 aluminum with an anodized finish. They are available in a range of sizes from 1/8” to six inches and 3mm to 150mm.
One of the main benefits of Clamp style shaft collars is their versatility. The collars can be used as guides, spacers, or stops on a variety of medical equipment. They are designed to distribute compression forces around a shaft, and they can be added at any stage in the manufacturing process.

Set screw shaft collars

Set screw shaft collars are used to secure screws to shafts. They can be purchased in a variety of sizes. The external diameter, internal diameter, and width of the collar will determine the proper collar size. Some companies also offer custom and adjustable-width collars. Clamp-style shaft collars are easier to maintain, and distribute torque evenly across the shaft. They also offer twice the holding power of set screw collars.
Collars are available in metric and inch sizes. They are also available in zinc plated and black-oxide steel. In addition, they come in a variety of styles. Whether you’re looking for a custom collar, or something a little more conventional, you can find it with the help of an ISO-certified supplier.
Set screw shaft collars come in different sizes and materials. Socket collars, for example, are made of steel and have an inside diameter of 5/64″ to 1-1/8″. In addition, forged socket set screw shaft collars come in 3/16 to 4 in. They are also available with special hardware for connection to shafts.
Set screw shaft collars are commonly used on transmission and machinery. A set screw allows you to secure the collar in position by setting it into the correct position with a grub screw or a set screw. The set screw can then be adjusted with a screw driver and is a quick and easy solution for keeping a shaft in place.
Shaft Collar

Aluminum shaft collars

Aluminum shaft collars offer a number of advantages, ranging from their light weight to their corrosion resistance. Aluminum shaft collars are available in various styles and sizes, and can be plated with a variety of finishes. They are also available in lightweight styles for applications with tight space constraints. The most important factor when selecting a shaft collar is the material used to make it. Aluminum is lighter than steel and has a high strength to weight ratio. The choice of material should also depend on how much corrosion resistance is required. For example, if the shaft will be exposed to extreme environments, it is a better choice to use treated steel.
Another benefit to aluminum shaft collars is their ability to be custom-matched to the shaft. This feature helps to increase their aesthetics and branding potential. In addition, the ability to color-code components and switches can improve safety. This is especially useful in fail-safe applications. By incorporating color-coded collars, manufacturers can increase the safety of their products.
Another advantage of aluminum shaft collars is their strength. For instance, they can withstand higher torque levels than other types of shaft collars. They can be easily adjusted, and their two-piece design makes them easy to replace. Moreover, CZPT keeps the two-piece collars together during manufacturing, ensuring a perfect fit for the shaft. These collars also feature forged steel socket screws for enhanced holding power and torque capacity.
Single-piece shaft collars are also available in various styles. The set screw type has a perpendicular outer face. The set screw in these collars is used to engage the mating shaft. This type of shaft collar is a good choice for rotating assemblies.
Shaft Collar

Stainless steel shaft collars

The main function of a stainless steel shaft collar is to provide clamping force to a rotating shaft. This is achieved by a variety of methods. One of these is by bending or hammering. A shaft collar can also be made of aluminum or a combination of both. These options provide different advantages, which are described in this article.
Stainless steel shaft collars are available in different sizes, shapes, and materials. The diameter of the shaft collar may range from five-sixteenths to two-and-a-half inches. Some manufacturers produce the collars in different materials, including T304, T316, 416, and 17-4PH. Their products may also come in various shapes, such as angles, flats, structural shapes, and threaded rods.
One of the most important advantages of a stainless steel shaft collar is its strength and durability. A well-made collar can prevent wear and tear and provide excellent holding power. It also has many applications and is useful in many industries. Its application ranges from vertical conveyors to horizontal athletic equipment machinery, from agriculture to retail.
While there are numerous types of shaft collars, all three types have some common characteristics. Typically, steel shaft collars have high holding power and slim to average profiles. Heavy-duty collars have twice the holding power of low-profile collars and are used in heavy-duty construction and mining. Ultra Heavy-Duty shaft collars have the highest axial holding power and are made of steel. Shaft collars may be treated with zinc for corrosion resistance.
One manufacturer offers stainless steel shaft collars made of 303 stainless steel and other materials. It offers collars of various diameters from three-eighth to one-eighth inch. They are available in threaded, mounting, and heavy-duty styles, and are suitable for a wide range of applications, including the aerospace, energy, and medical industries.

Types of Shaft Collars

Quick-clamp shaft collars

Quick-clamp shaft collars are a convenient option for tightening and loosening shafts. Unlike traditional bolts, quick clamps do not require any tools to install and adjust them. These collars come with flush handles and are designed to reduce production downtime. They also feature high-strength tension adjustment screws for compatibility with a wider range of shaft tolerances.
Quick-clamp shaft collars are offered in a variety of styles. CZPT, for example, offers a unique style of quick-clamp shaft collars with an integral lever. This lever sits flush against the outside diameter and is finger actuated. In addition, this design includes a tension-adjustment screw that can be adjusted according to the application’s requirements. Another style of quick-clamp shaft collar is a one-piece clamping collar with an integrated handle. It is ideal for low-rpm applications, and is designed to be a quick and simple solution for frequent shaft changeovers.
Quick-clamp shaft collars have an adjustable locking force generated by an eccentric lever and are very easy to install. They are available in one and two-piece clamp-type styles, and come in more than thirty standard sizes. They are available with round, square, and threaded bores. Additionally, you can choose to have them painted or customized.
Shaft Collar

Single split shaft collars

Single split shaft collars are a common choice for new installations. They provide easy installation and disassembly, which helps to minimize labor and downtime. They are also designed with full seating torque of the set screws, which evenly distributes forces throughout the shaft circumference. As a result, they provide greater holding power.
These shaft collars are available in various materials. They are typically made from different types of steel, including stainless steel and aluminium steel. They can also be made from nylon. The latter is available with different finishes, including black oxide. These are also available in custom sizes. These shaft collars are made to fit specific applications.
Single split shaft collars are available in a variety of sizes to fit a wide range of shaft diameters, from 1/8″ to 4 15/16″. The material used for the shaft should be softer than the material used for the set screw. They are marked with the bore size and are available in non-plated, chrome-plated, and black oxide coated materials.
Heavy-duty shaft collars are designed to hold a large amount of torque. They are available in two-piece clamp and one-piece clamp styles and offer up to 25 percent more holding force than standard collars. They are also available in a variety of materials, including proprietary black oxide finish, 1215 lead-free steel, 303 stainless steel, and high-strength 2024 aluminum.
Single split shaft collars are generally easy to install and remove. The design of these collars allows the shaft to fit into it evenly, which improves holding power. They also eliminate the need to remove or disassemble other components of the shaft. Additionally, they are easy to adjust and can work with virtually any shaft.
Single split shaft collars come in two-piece and one-piece styles. One-piece shaft collars are simpler to install and do not damage the shaft. Clamp-style collars are easy to use and do not require tools. They are designed to be hand-adjustable. These collars are recommended for light-duty applications. They are available in a wide range of threaded bore sizes. They also come in various styles, including ring-style and set-screw collars.
Shaft Collar

Set-screw shaft collars

Set-screw shaft collars are made of different materials, including steel, aluminum, and zinc plated steel. They are available in various widths and sizes. They can be used in aerospace, defense, and construction applications. Some types are standard, while others are custom-made.
A shaft collar has three primary functions: it holds a component in place, locates the component on a shaft, and creates an attachment between the shaft and another component. The design of a shaft collar depends on several factors, including the material, diameter, and geometry of the shaft.
One of the most common uses of shaft collars is to secure bearings and sprockets to shafts. In some cases, they also act as mechanical stops. For example, a two-piece clamp collar will wrap around the shaft without leaving any marks, while a set-screw collar will lock onto a shaft with a set screw. These types of collars can be used on predrilled and soft shafts.
Another advantage of set screw shaft collars is that they can be manufactured in a lightweight style for space-constrained applications. Another benefit is their ability to hold twice as much load as standard shaft collars. These collars are also available with a keyway, which makes them suitable for shafts with a key.
Another advantage of set-screw shaft collars is their safety. They were invented in the recessed socket screw industry and have become an industry standard. They prevent the shaft from sliding and causing a flanged bearing to come out. They are easy to install and remove, and they are ideal for light-duty applications.
Clamp style shaft collars are also available in one-piece and two-piece designs. This type of collar is unique in that it can be removed without damaging the shaft. They are also adjustable and can fit virtually any shaft. Their clamping force is evenly distributed around the shaft, so they are significantly safer than set screw collars, which use point-contact clamps.
Shaft Collar

Hinge shaft collars

The International series is a two-piece shaft collar with metric outer diameters, metric widths, and inch bores. These collars are suitable for many different types of applications, and are available in a variety of materials and bore sizes. They are available in 1215 lead-free steel with black oxide finish, high strength 2024 aluminum, and 303 stainless steel.
Custom Hinged Shaft Collars are a great choice for applications requiring quick and easy adjustment, especially in remote locations. They are available in a variety of materials, including steel, stainless steel, aluminum, and brass. You can even get custom-made collars for unusually shaped shafts.
Hinge shaft collars are similar to two-piece shaft collars in many ways. They allow easy disassembly and reassembly along the shaft and are usually the preferred choice in harsh environments. Hinge shaft collars have a simple design, allowing them to be installed quickly and easily. They also provide superior holding power. If you’re considering a hinge shaft collar for your application, it is important to consider how it will be used.
Hinge shaft collars serve as precise stops and spacers for different laboratory equipment. They can also be used on plastic, glass, and thin-walled tubes. They are often used in medical equipment, where the need for accuracy is paramount. They also serve as guides in optical measuring instruments. They are also useful in trucks and off-road vehicles, where they serve as mechanical stops.
Hinge shaft collars can be purchased in two-piece or one-piece designs. They can be adjusted using a single screw or lever. They can be installed and removed without causing any damage to the shaft. Unlike set screw collars, they don’t require tools. This makes them ideal for applications where access to the shaft is difficult or impossible. The advantages of these collars include improved safety and security.
