Disc Springs for Ball Bearing

Disc Springs for Ball Bearing, also be known as “Bearing Preload Disc
Springs”, they are assembled with the radial ball bearings, act as a
compensator of thermal expansions during their working.
Using Disc Springs to preload radial ball bearings, helps to maintain
positioning accuracy, eliminate shaft end play, and minimize vibration and
shaft deflection by distributing the load evenly around the bearing race,
extends the bearing life, eliminate excessive running noise. In most cases, the
outer race of the ball bearing is preloaded with the Disc Spring, and in some
cases it is desirable to preload the inner race of ball bearing. 
The recommended load value is achieved when the disc spring is deflected to 75%
of the initial cone heights (ho). The proper designed ho/t ratio makes a load
of disc spring remains nearly constant for a large deflection range. 
Disc springs for valves are designed to operate within 20%-80% of their total
deflection. Misuse can result in overload, bigger error, or premature fatigue
failure. If your working environment requires disc springs to work outside this
range, HEGONG SPRING ® engineers can provide guidance or recommend other
solutions. Be free to contact with our engineers Tech@DiscSpringsMFG.com.
