With every ball bearing there is radial play so it may function correctly.

This radial play or clearance can cause considerable noise at high speeds. In many cases it is possible to achieve a quiet running bearing assembly by the use of a suitable disc spring to apply an axial load to the bearing.

Similarly, the springs can be used to accommodate the build up of tolerances or thermal movements within the assembly.

In addition to the normal range ‘slotted’ springs are available up to a diameter of 95mm. This special design generates very small loads and will accommodate large deflections.

The load and dimension tolerances of DIN 2093 do not apply to this type of disc spring.
