How to Choose a Linear Ball Bearing and Round Shaft System Based on Load, Accuracy, & Environment 🤓
A replacement linear bearing can fit the shaft and still fail too soon. The carriage may bind, lose repeatability, require more drive force, or begin wearing a groove into the shaft.
That is why linear ball bearing selection cannot stop at shaft diameter and housing dimensions. Facility managers and maintenance technicians also need to consider load direction, shaft support, alignment, accuracy, contamination, and lubrication.
The goal is not simply to find a bearing that fits. Rather, the objective is to select a complete round shaft guidance system that can handle the application and remain practical to maintain.
