• 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.
