Smoothly & Noise-free
Ball bearings run smoothly and noise-free when pre-loaded with our Original SCHNORR® “K” disc springs. They are available in slotted and in non-slotted versions for bearings up to a diameter of 360 mm. Depending on the purpose for which they are used one or more disc springs may be specified.
The use of “K” disc springs has important advantages.
An important advantage of “K” disc springs is their shape of a simple ring. This ensures that the load which they apply to the bearing is distributed evenly around the bearing ring. Additional movement at constant load can be provided by arranging the springs in alternate direction (single series). Conversely, additional load can be applied at constant spring deflection when springs are arranged to face the same direction (parallel stacking).
As all springs are designed to have a highly regressive characteristic large (ho/t) spring load remains nearly constant for large spring deflection.
Advantages of K-Springs:
- The tolerances built up in the assembly can be accommodated without significant change in preload.
- Length variations through differential expansion can be accommodated. Any subsequent axial movement of the assembly does not alter the preload significantly.
- These are further advantages in addition to the elimination of original axial play.
