How can we improve?

2,082 Products

Raw Materials

Rubber

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

Foam

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

Building and Machinery Hardware

Bumpers

Absorb impact to protect equipment and surfaces from dents and scuffs

Vibration-Damping Mounts

Vibration-Damping Mounts

Attach to machinery to reduce vibration and noise and extend service life

Bellows

Prevent dust and debris from damaging moving parts

Power Transmission

Round Belts

Flexible to send rotary power between unparallel shafts

Disc Springs

Maintain tension and separate components on shafts, under bolt heads, and at the ends of valves

Shaft Couplings

Shaft Couplings

Connect two shafts to transfer rotary motion from one to the other

Idler Rollers

Guide boxes and parts as they pass through conveyor systems

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Sealing

O-Rings

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

Head Seals

Maintain a seal even under fluctuating pressure; more reliable than an O-ring with a backup ring

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

U-Cup Seals

With a lip on both the inside and outside edges, they can be used for sealing rods and pistons

Buffering Seals

Buffering Seals

Protect hydraulic cylinders from pressure spikes and shock in high-pressure applications

Backer Rods

Insert into gaps before caulking to reduce how much sealant you need and improve adhesion

Fastening and Joining

Cushioning Washers

Cushioning Washers

Cushion joints to dampen vibration and protect them from wear

Material Handling

Wheels

Move objects with ease

Skate Wheels

Replace wheels on skate wheel conveyors or add wheels for a custom setup

Ball Transfers

Install in arrays to create platforms for conveying, rotating, and positioning heavy objects

Drum Dollies

Instead of tilting heavy loads on drum trucks, roll drums upright to where you need them

Fabricating and Machining

Polishing Bobs

Attach to a drill or grinder to polish small and hard-to-reach areas

Containers, Storage, and Furniture

Drums

Ship and store large volumes of liquid or dry materials
