Cylindrical OD Housing Fit Guidelines
Tables 14-15 list t up guidelines for light load conveyor roll application per ABMA J6 t. Testing and experience
is needed to verify if this t is sufcient for specic operation conditions. If tighter press t is needed, contact
Application Engineering to review if the standard bearing internal clearance is sufcient or a modied clearance is
needed to prevent reduction or elimination of internal clearance.
For best reliability, bearings and housings should be selectively matched to reduce variation in t up due to
manufacturing tolerances of the bearing outside diameter and housing bore. Roll pockets should be machined
parallel with the axis of the shaft and both sides should be on the same centerline to minimize potential for
misalignment.

This chart displays the recommended housing dimensions for Sealmaster ER and Browning VER ball bearings at the various bore diameters and nominal
Outer Diameter. For Sealmaster ER with Skwezloc Concentric locking use the similar size ER with setscrew locking as shown. For other Browning Cylindrical
O.D. bearings use the similar nominal dimensioned bearing.
* Outside diameter may be slightly oversized due to seal press t, dimensions listed are as measured prior to seal assembly.
