Length variations due to heat impact are absorbed
The tolerance built up in the assembly can be accommodated without significant change in preload
Any subsequent axial movement of the assembly does not alter the preload significantly
Our K springs helps to reduce the noise and eliminates play in ball bearings. K springs can be used in singles or multiples, depending on the design. The bore holes also match the internal diameter of ball bearing sizes. For instance, a K spring that is suitable for pushing the external ring of a 6302 ball bearing can also be used to pretension the inner rings of 6205 and 6305.
