ABEC RUNOUT

The tolerances shown in the ABEC and ISO tables are specific for basic bearing dimensions and require no further explanation. The following information may also help the design engineer use the runout values shown for different tolerance ratings.

Outer ring: The total indicator reading during one complete revolution of the outer ring with the inner ring remaining stationary. Inner ring: The total indicator reading during one complete revolution of the inner ring with the outer ring remaining stationary.
FACE RUNOUT
Inner ring: The total indicator reading during one complete revolution of the inner ring with the outer ring remaining stationary.
Outer ring: The total indicator reading during one complete revolution of the outer ring with the inner ring remaining stationary.
FACE RUNOUT WITH BORE
The total indicator reading during one complete revolution of the inner ring.
O.D. RUNOUT WITH FACE
The total indicator reading during one complete revolution of the outer ring. The outer ring is positioned against 2 stops oriented at 90° to each other.
