||Refer to Minimum load of standard bearings.
When compared to a bearing with steel rolling elements, hybrid bearings are less sensitive to skidding and smearing damage that occurs in lightly loaded applications, even if light loads are only a small part of a variable load cycle.
(→ Axial preload)
|To provide low noise and high-speed operation, typically an axial preload to a bearing arrangement comprising two hybrid deep groove ball bearings is applied. Axial preload can be applied with spring washers, as described under Preloading with springs.
