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.
Deflection is the distance a spring compresses under load.
