Wave Disc Springs

Use these high-carbon steel springs in noncorrosive environments.

Corrosion-Resistant Wave Disc Springs

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

Split Wave Disc Springs

A gap allows these springs to compress without widening, so they won't bind or deform when used inside a housing with tight clearance.

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.

Stacked Wave Disc Springs

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

Belleville Disc Springs

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.

Belleville Disc Springs

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Belleville Disc Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs. Use them on shafts, bolts, and the ends of valves to maintain tension and separate components.

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.

Mil. Spec. Belleville Disc Springs

These springs meet MIL-W-12133.

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.

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.
