Abstract

A taper roller bearing is described which has the particular feature of having the track of the inner ring capable of being inspected, such characteristic is obtained by means of a spacer cage the bridges of which extend both above and below the roller pitch circle identified by the axes of the rollers in such a way as to retain these latter in the pockets of the cage both on the outer ring side and on the inner ring side of the bearing; the cage in the pockets of which the rollers are snap-engageable, is removable together with the rollers of the track of the inner ring, being axially fixed to this latter by snap-engagement.
