Depending on the type of cage, some bearings may not be suitable for use under harsh operating conditions close to the bearing's rated speed, limit temperature, or with a small amount of lubricating oil, large vibration and moment loads. In this case, please contact NSK in advance. In addition, during the operation of NSK angular contact ball bearings, if the bearing load is too small, the ratio of the paired double bearing to the radial load exceeds the value of e (recorded in the bearing dimension table), and there will be sliding between the ball and the raceway. cause abrasions. Especially large angular contact ball bearings have this tendency. Please contact NSK when such load conditions are encountered. For the installation of angular contact ball bearings, due to structural reasons, a single bearing can only bear the load in one direction. Therefore, when mounting to a shaft or housing, it is very important that the external load is only applied to one side that can bear the load and not the other side. When combining bearings, the order of loading them into the shaft bearing housing is different for back-to-back and face-to-face combinations, so be careful. Scratches on the ball If a load is applied in the X direction, the ball may be scratched. Figure 7 Temperature (°C).
