Title:
AUTOMATIC SELF-ALIGNING ROLLER BEARING
Document Type and Number:
Japanese Patent JP2009180235
Kind Code:
A
Abstract:
To reduce heating and vibration caused by operation, and to restrain abrasion by suppressing abrasion when a cage 5 and a guide ring 6 relatively rotate, when operating an automatic self-aligning roller bearing 1a.
A radial needle bearing 15 is incorporated between the cage 5 and the guide ring 6, and the cage 5 and the guide ring 6 are relatively rotated via the radial needle bearing 15. This constitution can solve the problem by preventing an inner peripheral surface of a rim 10 constituting the cage 5 and an outer peripheral surface of the guide ring 6 from slidingly contacting with each other.
