About Shaft Collars
Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Light Duty Dry-Running Thrust Bearings
Use where high loads and speeds are not required.
Thermoplastic bearings are fiber reinforced and lubricant infused for good wear resistance and low friction with light and medium loads.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

High-Load Dry-Running Thrust Bearings
A steel backing adds strength to these slippery PTFE bearings.

Set Screw Shaft Collars
Keep these shaft collars in place by tightening their set screw into the shaft. The tip of the screw digs in for a secure hold, but will mar the shaft’s surface. For maximum holding power, make sure the set screw material is harder than your shaft material. Use these shaft collars to position and retain power transmission components such as sprockets, pulleys, and bearings. You can also use them to limit the movement of a shaft.
Carbon steel collars are strong and wear resistant. Collars that are blue make it easy to identify metric collars at a glance. They’re tinted to match other blue metric fasteners.
303 stainless steel collars are corrosion resistant and highly machinable.
DIN 705 collars meet an international standard for shaft collar dimensions.

Clamping Shaft Collars
These metal collars are stronger than plastic shaft collars. They clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screw to secure.
Black-oxide steel collars have some corrosion resistance.

Tight-Hold Quick-Release Clamping Shaft Collars
A threaded lever lets you tighten these collars with more torque than other quick-release styles, ensuring that they stay put on your shaft. Use them to quickly move components or make setup changes, such as on packing equipment, printers, or label feeding machines. To make adjustments in tight spaces, lift the lever and twist to the side. Similar to a ratchet, you can lift the lever to disengage from the threads and reposition.
Black oxide steel collars are very strong, but will rust if exposed to moisture.
Anodized aluminum is strong and lightweight. It can withstand humidity without rusting, but water left on the surface will cause it to corrode.
303 stainless steel collars can handle frequent exposure to water without rusting.

Clamping Two-Piece Shaft Collars
These metal collars are stronger than plastic shaft collars. The two-piece design allows you to install them anywhere on a shaft without removing components or having access to the ends of the shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.
Black-oxide steel collars have some corrosion resistance. Aluminum collars are lightweight and have good corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Washdown Clamping Two-Piece Shaft Collars
Suitable for use in washdown applications, these plastic collars also offer good chemical resistance. The two-piece design allows you to install them anywhere on a shaft without removing components or having access to the ends of the shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.
Acetal collars have a naturally slippery surface and resist swelling when exposed to moisture.

Quick-Release Two-Piece Clamping Shaft Collars
Make quick adjustments to these shaft collars with a lever on the side. Often used on packing equipment, printers, and label feeding machines, these collars are used to quickly move components or make setup changes. To make adjustments in tight spaces, lift the lever and twist to either side. Similar to a ratchet, you can tighten and loosen with the lever down; lift the lever to disengage from the threads and reposition. The two pieces of the collar separate, so you can install them anywhere on a shaft without removing components or having access to the end.
