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.

Oil-Embedded Sleeve Bearings
Startup friction causes these 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.

Oil-Embedded Thrust 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.

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. Collars with a zinc-plated finish have an outer layer of zinc that protects the steel from rust and extends the life of the collar. Aluminum collars are lightweight and have good corrosion resistance.

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.

Extra-Grip Clamping Shaft Collars
With larger clamping screws than those found on standard clamping collars, these provide a stronger grip on your shaft without using additional screws. 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. Collars are black-oxide steel, which offers some corrosion resistance.

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. Zinc-plated steel and chrome-plated steel collars have moderate corrosion resistance with a bright finish. Aluminum collars are lightweight and have good corrosion resistance. 303 stainless steel collars have excellent corrosion resistance. 316 stainless steel collars have excellent corrosion and chemical resistance.
