Proprietary bearing design and specifiions as well as our proprietary bearing fit and preload adjustment; It fits over the spindle in between the wheel bearing cones and acts as a spring to provide a lateral clamp force on the bearing cones. This assists in preventing cone rotation on the spindle and reduces associated wear.
Lubriing greases: sustainable protection from wear
Basically, grease lubriion is the most obvious choice when the design of an industrial appliion rules out the use of oil lubriion. An example of grease appliions is spindle bearings in machine tools, which rotate very fast and have low surface pressure. For large drives with high surface pressures and low speed, by contrast
