Shock Absorbers

Self-Adjusting Shock Absorbers

Accommodate changing loads and energy without manual adjustment.

Corrosion-Resistant Self-Adjusting Shock Absorbers

Made from stainless steel for excellent corrosion resistance in damp environments.

Adjustable Shock Absorbers

Turn the knob on these shock absorbers to change deceleration to suit varying loads and speeds.

Light Duty Adjustable Shock Absorbers

Also known as snubbers, use these shock absorbers in low-load, high-cycle applications.

Leak-Resistant Adjustable Shock Absorbers

An airtight seal prevents leaks and protects moving parts from dust to minimize wear for a long service life.

Long-Length Shock Absorbers

Like the shocks in a car, these mount between two surfaces to minimize vibration and motion transfer caused by sudden impact.

Springs

High-Load Fastener-Mount Compression Springs

These springs handle higher loads than standard fastener-mount compression springs. Secure by inserting a fastener through the hole at the base.

Ultra-High-Load Fastener-Mount Compression Springs

For the heaviest loads, these springs have more than double the load capacity of High-Load Fastener-Mount Compression Springs. Secure by inserting a fastener through the hole at the base.

Fastener-Mount Compression Springs

Differently sized mounting holes on either side allow for mounting flexibility.

Flanged Compression Springs

Flanges on the ends of these springs provide a flat mounting surface.

Corrosion-Resistant Die Springs

A quieter, more vibration-resistant alternative to traditional steel die springs, these polyurethane springs resist oxidation, oil, and abrasion in high-load, high-pressure applications.

Adjustable Air Springs

Isolate vibration and absorb shock from moving equipment, even with changing loads. Also for leveling and lifting, use compressed air to adjust air springs to the height and force required for your application.
