Insert bearing
Insert bearings are based on sealed deep groove ball bearings. They have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft. SKF supplies insert bearings in many designs and variants and with several sealing arrangements.
Check locking method, housing compatibility, seal design, lubrication, contamination level, and load condition.
