A study on the smearing and slip behaviour of radial cylindrical roller bearings
- Knowledge of the features and qualities of a machine element are essential foundations for its successful operation. High grade materials, more accurate calculation methods and modern manufacturing processes lead to continuous design and performance improvements and hence increased power within minimised spatial requirements. INA cylindrical roller bearings, series SL 1923.., ZSL 1923.. and LSL 1923.. follow this trend and due to their high performance characteristics and low physical volume they have obtained a firm place as high performance machine elements. Essential characteristics of radial cylindrical roller bearings are their behaviour regarding kinematics, noise, vibration, dynamic frictional torque, cage speed, speed of a rolling element, slip etc. The paper gives details of the kinematic behaviour concerning the relationship between the roller set speed or the cage speed and the speed of a rolling element in connection with the occurrence of smearing. This kind of damage occurs during the running in stage of a machine and isKnowledge of the features and qualities of a machine element are essential foundations for its successful operation.

This kind of damage occurs during the running in stage of a machine and is becoming very important because of the enormous costs which are caused by down time and lost production.…
