How can we improve?

2,545 Products

Raw Materials

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Graphite

Compressible or conductive for making high-temperature seals, furnace parts, and crucibles

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Carbon

An electrical conductor that’s often used in electronics and sensors

Plastic

A lightweight alternative to metal and glass

Aluminum

Lightweight, easy to machine, and corrosion resistant—all with material certificates for traceability

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Power Transmission

Bearing Adapter Sleeves

Bearing Adapter Sleeves

Close gaps between your bearing and shaft for a tight fit

Ball Bearings

Create less friction than other bearings for use at high speeds

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Linear Shaft Supports

Linear Shaft Supports

Support linear shafts to prevent bending and rolling under loads

Building and Machinery Hardware

Wear Plates

Often used on conveyors to reduce friction where parts bump into equipment to extend service life
