Linear ball bearing, load carrying element therefor, production method and forming device for a blank of the load carrying element

摘要

#CMT# #/CMT# The bearing (1) has a recirculating ball (9) with bearing balls (90), which are rollably supported at a raceway of a carrier track element (8). The carrier track element is directly or indirectly inserted into a cage (4), and comprises a radial outer surface for attachment to an inner surface of a part (3) surrounding a guide rail (2). The outer surface is curved outwardly in a direction and is formed by a rod-like projection, which is extended in a longitudinal direction of the carrier track element. The projection is arranged at a middle region of the track element. #CMT# : #/CMT# Independent claims are also included for the following: (1) a method for manufacturing a carrier track element (2) a device for forming a blank of the carrier track element. #CMT#USE : #/CMT# Linear ball bearing for a longitudinally displaceable storage of shaft-like guide rail in a part e.g. drive spindle and bearing housing of machine tool, surrounding the guide rail. #CMT#ADVANTAGE : #/CMT# The outer surface of the carrier track element is curved outwardly in the direction and is formed by the rod-like projection, which is extended in the longitudinal direction of the carrier track element, thus reducing the outer surface, without loss of load bearing capacity, and hence manufacturing the linear ball bearing in a cost-effective and simple manner, and sufficiently compensating misalignment of oppositely movable components. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a linear ball bearing. 1 : Linear ball bearing 2 : Guide rail 3 : Part 4 : Cage 8 : Carrier track element 9 : Recirculating ball 90 : Bearing balls.
