Rolling bearing with insulating sleeve

摘要

The bearing (5) has an inner race arranged radially outside an outer bearing race between shifting rolling members and a collet (11). A radially inward curved board is secured at an external periphery of the outer bearing race. The collet forms acoustic and electrical insulation of the bearing. The collet comprises two annular shoulders at external periphery, where the annular shoulders are separated from each other by an annular groove. The collet is made of steel and plastic coating that does not transmit electric current.
