four-point contact ball bearings internal clearance

Kaydon type X – four

The Reali-Slim type X four-point contact ball bearing is distinguished from types A and C by the geometry of its ball grooves In type C bearings the centers of the radii both lie in the plane of the ball centers In type A bearings the races and balls are in angular contact and the centers of the groove radii are offset equal amounts on

Radial Ball Bearing Internal Clearances – RBI Bearing Inc

Defined by ISO Standard 5753-1981 ANSI Standard 20 internal clearance refers to the total distance one bearing ring moves relative to the other – radially or axially Mounted and un-mounted clearance measurements will differ This is due to interference fits that could occur between shafts and bearing bore as well as the housing and bearing []
