How can we improve?

8,522 Products

Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Roller Bearings

Roller Bearings

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

Mounted Bearings

Mounted Bearings

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

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Thrust Bearings

Thrust Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Bearing Washers

Bearing Washers

Adapt needle-roller thrust bearings for use on unhardened, unground surfaces

Bearing Shaft Liners

Bearing Shaft Liners

Adapt precision needle-roller bearings for use on unhardened, unground shafts

Linear Bearing Housings

Linear Bearing Housings

Hold linear ball or sleeve bearings by sliding them in and securing with retaining rings

Guide Rail Carriages

Guide Rail Carriages

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

Linear Motion Slides

Linear Motion Slides

Move loads on accurate and repeatable paths beyond the mounting surface

Telescoping Rails

Telescoping Rails

Connect multiple rails to create custom positioning tables or telescoping slides

Ball Screws and Nuts

Ball Screws and Nuts

Internal ball bearings roll on screws for low friction when moving components at high speeds

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Roller Screws and Nuts

Roller Screws and Nuts

More contact points to move heavier loads than ball and lead screw assemblies

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
