About Linear Bearings

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.

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. 316 stainless steel collars have excellent corrosion and chemical 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

Without Keyway

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. In addition to the benefits of aluminum, anodized aluminum collars have extra corrosion resistance, and you can tighten the clamping screw with more torque, so they stay in place.

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.

Mounted Linear Bearings for Spline Shafts

Ready to mount on your linear motion spline shaft, these bearings come installed in a housing and have grooves that match up with the splines on your shaft. Because they’re splined, they transfer rotational force as they move loads up and down the shaft’s length. A flanged end makes them best for lifting and lowering loads on vertical shafts. All have fixed alignment—use them where shaft misalignment is unlikely.

Ball bearings, also known as ball splines, create less friction than plain bearings, making them smooth and precise even at high speeds. However, they don’t produce as much rotational force. Choose them for robotic systems and other automated applications that require complex, fast movements.
