Compression Spring Stock

Use these steel springs in noncorrosive environments.

Confined-Space Conical Compression Springs

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

Linear Wave Springs

Similar to disc springs, these linear springs are good for absorbing vibration and filling in gaps along the length of an object.

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.

Disc Springs

Curved Disc Springs

Use these high-carbon steel springs in noncorrosive environments.

Notched Disc Springs

Notches make these springs more flexible than Belleville disc springs and allow liquid to flow around the spring, even while it's in use.

Wave Disc Springs

Use these high-carbon steel springs in noncorrosive environments.

Stacked Wave Disc Springs

Multiple rows of waves allow these springs to handle higher loads than standard wave disc springs.

Corrosion-Resistant Stacked Wave Disc Springs

Made of 17-7 PH stainless steel with multiple rows of waves, these springs are more corrosion resistant than steel springs and handle greater loads than standard wave disc springs.

Corrosion-Resistant Curved Disc Springs

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

Extreme-Temperature Belleville Disc Springs

These springs withstand temperatures from -400° to 1100° F. All are 718 nickel, a high-strength, corrosion-resistant alloy that's also known as Inconel.

Belleville Disc Springs for Flange Bolts

Keep pipe flange connections sealed during demanding applications. When installed under flange bolt heads, these springs compensate for shock loads, vibration, and thermal expansion and contraction.

Belleville Disc Springs for Ball Bearings

Install these springs, also known as bearing preload washers, against ball bearings to reduce noise and unwanted movement along the shaft.

Finger Disc Springs

Raised tabs, known as fingers, enable these springs to compress without widening, so they won't bind or deform in housings with little clearance. Use with ball bearings in precision and high-speed drive assemblies to reduce noise, vibration, and wear.

Strip Springs

Variable-Force Springs

Unlike constant-force springs, the farther you pull these, the harder they are to pull. Use them for applications where the load becomes lighter as the spring contracts, such as in automated dispensing machines.

Constant-Force Springs

No matter how far you extend them, these springs pull back with the same amount of force.

Clip-On Constant-Force Springs

Clip the end onto a flat surface to install—no fasteners needed. Once installed, these springs pull back with the same amount of force no matter how far you extend them.

Rotor Springs

Wind these springs to store power, then release them to create rotary motion—similar to winding a wristwatch. Also known as clock springs and power springs.
