Multipurpose Flanged Sleeve Bearings
These bronze bearings are strong, wear resistant, and excellent at handling shock loads. They’re sometimes called 660 leaded bronze 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.

Quick-Disconnect (QD) Bushings
The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) 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.

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.

Flush-Mount Screw-Clamp Bushings
Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

Corrosion-Resistant Flush-Mount Screw-Clamp Bushings
Insert these nickel-plated steel bushings into the bore of your sprocket for flush or recessed mounting in wet environments. When you tighten the included clamping screws on these bushings, their inner sleeve contracts onto the shaft and their outer sleeve expands to hold your sprocket, pulley, or gear. This keeps bushings from slipping during sudden starts and stops.

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

Clamping Two-Piece Shaft Collars with Wrench Flats
Use a wrench to rotate your drive shaft without marring or gouging the shaft. Fasten one of these collars onto your shaft, position a wrench on the collar’s wrench flats, and then rotate the entire shaft/collar assembly to adjust the shaft. The two-piece design allows you to install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Tighten the clamping screws to secure.
Black-oxide steel collars have some corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Set Screw Two-Piece Shaft Collars
Tighten the set screw to bite into an unhardened shaft for a secure hold. The two-piece design allows you to install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Clamping screws provide extra grip.
Carbon steel collars are strong and wear resistant. Their black-oxide finish is somewhat corrosion resistant, 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.

Weldable Two-Piece Shaft Collars
Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Because they’re grade 1018 carbon steel, you can easily weld them to other components. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.

Set Screw Flexible Shaft Couplings
Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place. Also known as Lovejoy® couplings, these three-piece couplings have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment.
Buna-N spiders provide good vibration damping and chemical resistance. Hytrel spiders provide fair vibration damping and excellent chemical resistance.

High-Temperature Linear Ball Bearings
The choice for low-friction motion in high-temperature environments. Bearings are for use with round end-supported shafts and have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).
