Radial play refers to the internal clearance between bearing balls and races in the radial direction, affecting shaft wobble. Axial play is the clearance in the axial direction, affecting endplay. Both must be minimized for encoder accuracy.
Most encoder bearings are sealed and lubricated for life. In high-speed or high-temperature applications, relubrication may be needed every 10,000-50,000 hours depending on operating conditions.
Typically, shafts and bearings are replaced as an assembly since wear patterns develop together. However, precision shafts can sometimes be reused with new bearings if within tolerance specifications.
