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

Oil-Embedded Sleeve 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.

Split-Tapered Bushings
The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.

Quick-Grip Screw-Clamp Bushings
Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.

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 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. Zinc-plated steel collars have moderate corrosion resistance. Anodized aluminum collars are lightweight like unfinished aluminum collars, but they’re more corrosion resistant and have better screw seating torque, which means they’re less likely to shift. 303 stainless steel collars have excellent 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
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. 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. 303 stainless steel collars have excellent corrosion resistance. 316 stainless steel collars have excellent corrosion and chemical resistance.

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.
