General Information
ABIS Preload Springs For ball bearings
Preloading of bearings is a crucial process that involves applying an axial load to either the inner or outer ring of the bearing. This ensures that radial play is taken up, and running components are in consistent contact. Using a bearing preload spring is seen as a best practice as it significantly reduces noise and vibration, ultimately extending the life of the bearing.
There are essentially two methods to preload a bearing. Firstly, a solid preload, such as a threaded plug or circlip. Secondly, by a spring, specifically a disc spring. The disadvantage of a solid preload is that it cannot compensate for tolerance build-up or thermal expansion of the surrounding components, which may affect the running torque.
Bearing preload springs, particularly disc springs, offer a superior solution. The disc spring, by applying a constant load around the bearing ring, overcomes the limitations associated with solid preloads. In applications where a very light preload is required, the disc spring can be designed with radial slots to reduce the axial force applied.
IEC provides a comprehensive range of bearing preload springs from ABIS, designed to meet various application requirements. Our springs ensure consistent performance and reliability by maintaining optimal contact and load distribution in ball bearings.
