Bearing Preload Spring Washer

This distinctive shape produces spring pressure when the wave washer is somewhat compressed.

Bearing preload spring washer.

The first is solid preload which is achieved by holding inner and outer races in place with a locking mechanism. Wave spring washers are suitable for a variety of bearing applications where a small deflection may be required. Designed for use with bearing nuts these lock washers have a conical shape that presses like a spring against bearings bushings gears and pulleys to hold them in place on your threaded shaft or spindle. There are essentially two methods to preload a bearing.

Spring preloading provides a relatively constant preload because it is less sensitive to differential thermal expansion and can accommodate misalignment. An axial preload ensures constant contact between the ball complement and bearing races reducing or eliminating both modes of play. Wave spring washers are suitable for a variety of applications where a small deflection is required. Flat load is the load at which the spring is completely compressed.

Metric tab lock washers. This means a lot of deflection must generated with as little increase in spring force as possible. It is particularly common to use wave washers to take up end play and for the loading of bearing assemblies. Properly preloading a bearing can increase its life and eliminate the.

Preload disc springs can also be useful in other applications. Preloaded bearing springs have a smaller flank ratio o d i d than standard disc springs due to the small installation space available. Install these springs also known as bearing preload washers against ball bearings to reduce noise and unwanted movement along the shaft. Preloading of bearings is a process of applying an axial load to either the inner or outer ring of the bearing so that radial play is taken up and running components are in contact.

There are two main methods to preload a bearing. This is seen as good practice as it reduces noise vibration and ultimately extends bearing life. Correct preloading will also increase bearing rigidity and negate excessive running noise. The more common simpler and less expensive method is spring preload which is achieved by using a spring to apply a constant axial load on one side.

Some ball bearing applications require a softer deflection behaviour at the beginning of deflection. Spring preload a versatile execution of bearing preload utilizes single turn wave springs to add the necessary preload forces despite dimensional variation and thermal expansion. Wave spring washers to for loading ball bearings and other purposes. The preload disc springs or washers assist in maintaining positioning accuracy of the bearing with no end play and also minimise vibration and shaft deflections.

Bearing preload is the process of adding a sustained axial load independent of external loads to a bearing. Unlike belleville washers they return to their original height once working loads are removed. Deflection is the distance a spring compresses under load.
