These zinc-plated steel springs have mild corrosion resistance.

Extra-Stretch Extension Springs

These fabric-covered rubber springs stretch to up to three times their original length—much farther than traditional extension springs, tie downs, and shock cords.

Corrosion-Resistant Extension Spring Stock

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

Extension Spring Stock

Use these steel springs in noncorrosive environments.

Compression Springs

Use these springs in noncorrosive environments.

Corrosion-Resistant Compression Springs

These springs are more corrosion resistant than standard compression springs.

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Compression Spring Stock

Made of stainless steel, these springs are more corrosion resistant than steel compression springs.

Precision Compression Springs

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Precision Compression Springs

Made of stainless steel, these springs are more corrosion resistant than steel compression springs.

Plastic Compression Springs

A lightweight, nonmagnetic, and nonconductive alternative to metal springs, these plastic springs are better for corrosive environments and applications where metal springs cannot be used, such as in sensitive imaging equipment and machines where stray electrical current may cause damage.

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.

Fastener-Mount Compression Springs

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

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.

Confined-Space Conical Compression Springs

Install these springs in tight spots. When pushed together, the coils nest within each other.

Torsion Springs

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Torsion Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs.

Made-to-Order Torsion Springs

Whatever the size, we'll get the spring you need.

Die Springs

Color-Coded Die Springs

These springs follow the Raymond die spring color code.

Metric Color-Coded Die Springs

Colors and sizes follow ISO 10243 for metric die springs.

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.

Die Spring Stock

Keep these 36" springs on hand so you can cut the right length whenever you need it.

Die Springs

Use these spring-tempered steel die springs for low-cycle applications such as trimming and stamping.

Garter Springs

With ends that are connected to form a circle, these garter springs exert strong radial (towards the center) forces from all directions to maintain pressure on shafts or in seals.

Spring Assortments

Compression Spring Assortments

When compression springs are pushed together, they push back to return to their original length. Commonly used in shock absorbers and to secure batteries, they're are easier to push together than die springs.

Elongated-Hook Extension Spring Assortments

The springs in these assortments have deep hooks that are less likely to slip off compared to standard extension springs.

Extension and Compression Spring Assortments

These assortments include springs that pull and springs that push.

Extension, Compression, and
Torsion Spring Assortments

Keep a collection of three of the most common types of springs on hand.

Extension Spring Assortments

The more you extend these springs, the greater the force the springs will exert to pull the two points back together. They're commonly used to tension cable, return an air cylinder to its starting point, and hold a door closed.

Shock Absorbers

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.

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.

Gas Springs

Color-Coded High-Force Miniature Gas Springs

Color coded by force to help you choose the correct replacement, these gas springs generate high force in small spaces.

High-Force Miniature Gas Springs

Small in size, but not in strength, these gas springs are often used to replace coil springs in metal stamping and die-spring applications.

Reducible-Force Gas Springs

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Corrosion-Resistant Reducible-Force
Gas Springs with Eyelet Fittings

Made from stainless steel for excellent corrosion resistance in damp environments. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Corrosion-Resistant Reducible-Force
Locking Gas Springs

Release gas from these springs until they supply the exact force you need—made of corrosion-resistant 316 stainless steel, they’re commonly used in wet environments.

Reducible-Force Locking Gas Springs

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

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.

Building and Machinery Hardware

Adjustable-Force Extension Spring
Storm Door and Gate Closers

These closers consist of two interconnected springs—twist them to adjust closing force. The springs retract to pull storm doors and gates closed.

Tight-Clearance Gas Spring Storm Door Closers

Use these closers when your door-to-door clearance is limited. They close storm doors more smoothly than standard spring closers.

Gas Spring Storm Door Closers

Close storm doors more smoothly than standard spring closers.

Adjustable Extreme-Force Bolt-Down
Vibration-Damping Mounts with Threaded Hole

Connect these mounts to your air supply for vibration and shock isolation in compression load applications.
