Thrust Bearings

Thrust Bearings

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

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Bearing Housings

Bearing Housings

Mount your own bearings in place

Turntable Bearings

Turntable Bearings

Linear Bearing Brakes

Linear Bearing Brakes

Lock bearings in place on a shaft for precise positioning

Track Rollers

Support and carry objects as they move along conveyor systems

Drive Rollers

Transmit power from motors to systems like conveyors; also known as contact wheels and feed rollers

Rod Ends

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

Rod End Seals

Keep dirt out and lubrication in to extend the life of rod ends

Rod End Inserts

Rod End Inserts

Attach to rod ends to increase the amount of misalignment they can handle

Swivel Joints

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

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

Mount between a rotating shaft and equipment to secure the shaft and reduce vibration

Shaft Collars

Hold and position parts on a shaft, or limit shaft movement

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Ball Screws and Nuts

Ball Screws and Nuts

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

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Ball Screw/Splines

Ball Screw/Splines

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Bore Reducers

Adapt the bore of a component to a smaller size for mounting on a shaft

Roller Screws and Nuts

Roller Screws and Nuts

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

Positioning Slides
