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 valvesare 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
In case use disc springs stack set supplier, it is noting that the ho/t ratio in excess of 1.50 could cause disc springs to invert and collapse.
OD of Disc Springs for Ball Bearing is 9.8 – 358mm (0.386’-14.1’)
