INNER GAB RING OF BACK-TO-BACK ANGULAR CONTACT BALL BEARINGS

摘要

An inner gap ring of the back-to-back angular contact ball bearings has unique characteristics as a ring with a threaded outer surface (1), when the inner gap ring of the back-to-back angular contact ball bearings is used to install back-to-back angular contact ball bearings, the gaps in round ball bearings with corner contacts can be determined as preferred without sloping of the ball bearings, thereby making, the gaps inside the angular contact ball bearings even at every point.
