Raw Materials

Foam

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

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Sealing

O-Rings

Fit snugly into a groove between parts to create a leak-resistant seal

O-Ring Cord Stock

O-Ring Cord Stock

Cut to length to create customized seals

Hose Washers

Place inside nozzles and spigots to prevent leaks in an attached hose

Pipe Gaskets

Form tight seals when connecting flanged pipe fittings

Manway Gaskets

Create a tight seal between the nozzle and lid of tank car manways

Fastening and Joining

Sealing Washers

Sealing Washers

Prevent fluids from leaking around fasteners

Power Transmission

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Mounted Bearings

Mounted Bearings

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

Round Belts

Flexible to send rotary power between unparallel shafts

Idler Rollers

Guide boxes and parts as they pass through conveyor systems

Drive Rollers

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

Idler/Drive Rollers

Idler/Drive Rollers

Spin freely in one direction on conveyor systems and lock to transmit power in the other direction

Building and Machinery Hardware

Bellows

Prevent dust and debris from damaging moving parts

Bumpers
