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.

About Plain Bearings

Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.

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 Oil-Embedded Sleeve Bearings

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron. These bearings are also magnetic due to the high iron content.

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.

Ultra-Low-Friction Oil-Embedded Sleeve Bearings

For applications with frequent starts and stops, the oil in these bearings contains particles of slippery PTFE that lubricate the bearing during startup.

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 Ultra-Low-Friction Oil-Embedded Sleeve Bearings

With extra iron and filled with oil containing slippery PTFE, these bearings support heavy loads that frequently start and stop along shafts. Startup friction causes a thin layer of oil to release onto the surface. Their high iron content also means they resist failing if their load suddenly and drastically increases, but they won’t run as fast as standard bearings. As sleeve bearings, they handle loads parallel to the shaft.

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.

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 with a black-oxide finish have some corrosion resistance, but only in dry environments. Their dark color can be useful for matching other parts in your system. 303 stainless steel collars are corrosion resistant and highly machinable.

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. Aluminum collars are lightweight and have good corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

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. 303 stainless steel collars have excellent corrosion resistance.
