Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Bearing Shaft Liners

Bearing Shaft Liners

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

Flanged Sleeve Bearings

Flanged Sleeve Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

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 Bearing Housings

Linear Bearing Housings

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

Bearing Nuts

Hold bearings, bushings, pulleys, and gears in place on threaded shafts and spindles

Bearing Lock Washers

Bearing Lock Washers

Lock bearing nuts in place to prevent loosening due to vibration

Rod End Inserts

Rod End Inserts

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

Shaft Collars

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

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

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

Lead Screws and Nuts

Lead Screws and Nuts

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

Fabricating and Machining

Drill Bushings

Fit in holes to guide drill bits and other cutting tools for precise and repeatable holes and cuts

Raw Materials

Bronze

With better wear resistance than copper and brass, it’s used for bearings, gears, and pump parts

Plastic

A lightweight alternative to metal and glass

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Fastening and Joining

Shims

Align and space components on shafts, or level machinery, cabinets, and doors
