One-Piece Thrust Ball Bearings
In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

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.

Extra-Clearance Mounted Ball Bearings
Keep shafts, such as those with a shoulder, clear of the mounting surface. These bearings have a higher mounting base that gives them more space to the mounting surface than standard mounting bases. All have a set screw for securing them to shafts without having to use a collar. The screw lets shafts rotate in both directions, so they’re good for applications where you need to reverse.

Easy-Align Mounted Ball Bearings with Two-Bolt Flange
An elongated mounting hole on one side of the flange lets you adjust the position of these bearings without having to remove your shaft. You only need to loosen the bolt instead of removing it to adjust. They’re self-aligning to compensate for shaft misalignment.

Taper-Lock Bushings
Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

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.
