Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Mounted Bearings

Mounted Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Thrust Bearings

Thrust Bearings

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

Roller Bearings

Roller Bearings

Support higher loads than ball bearings, but run at lower speeds

Track Rollers

Support and carry objects as they move along conveyor systems

Linear Motion Slides

Linear Motion Slides

Move loads on accurate and repeatable paths beyond the mounting surface

Ball Spline Bearings

Ball Spline Bearings

Pair with ball splines for applications requiring complex, fast movements, such as robotics

Material Handling

Conveyor Roller Bearings

Conveyor Roller Bearings

Replace bearings on conveyor rollers, or press into tubing or pipe to create a roller

Wheel Bearings

Reduce friction between the axle and the wheel for smooth movement

Fabricating and Machining

Router Guides

Make precise circular or intricate cuts with routers
