How can we improve?

3,211 Products

Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Flanged Sleeve Bearings

Flanged Sleeve Bearings

A sleeve and thrust bearing in one to support both parallel and perpendicular loads

Mounted Bearings

Mounted Bearings

Ball, roller, and sleeve bearings ready to bolt in place

Thrust Bearings

Thrust Bearings

Support loads parallel to the shaft with plain, ball, or roller bearings

Turntable Bearings

Turntable Bearings

Support machinery that slowly turns or oscillates, such as a rotating hoist

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Pivot Bearings

Best for applications that require small, precise oscillating motion with limited twisting

Swivel Joints

Handle shaft misalignment where ball joint rod ends won’t fit; also known as spherical bearings

Rod Ends

Use with connecting rods to support loads and control steering, tensioning, or pivoting motion

Carriages and Guide Rails

Carriages and Guide Rails

Carry loads along guide rails on accurate and repeatable paths in automated systems

Idler Rollers

Guide boxes and parts as they pass through conveyor systems

Track Rollers

Support and carry objects as they move along conveyor systems

Electric Slides

Electric Slides

Move parts with precision in electronics, robotics, and other automated processes

Positioning Slides

Positioning Slides

A lead screw drives the carriage for accurate positioning in laboratory and production equipment

Building and Machinery Hardware

Turntables

Rotate to reposition machinery and equipment
