Easy-Install Mounted Cylindrical-Roller Bearings
A split housing means you can remove the top half of these bearings to inspect or repair shafts and components. This reduces downtime and minimizes the risk of damaging surrounding components.
Bearings for radial loads accommodate minor changes in your shaft’s length as it expands and contracts from your machinery heating up and cooling down. They are typically used in assemblies with long shafts and positioned away from the drive end.
Bearings for combined radial and thrust loads anchor the shaft in position and absorb the thrust load. However, they are not designed to handle your shaft expanding and contracting. They’re typically mounted near the drive side of an assembly.

Hub-Mount Screw-Clamp Bushings
Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.

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.

Bearing Caps
Cover standard or flange-mount bearings to protect personnel from injury and keep contaminants out. Place caps over the entire bearing housing and drill holes in their flange to install with screws. If necessary, drill the caps for access to bearing grease fittings or to create space for a shaft to pass through, and trim the flange to fit in tight spaces.
Black ABS caps resist UV light, so they won’t color or crack when exposed to the sun.
