* In inches  L = Loose Fit  T = Tight Fit  d = Bearing Bore as listed  D = Bearing O.D. as listed  ** Bearing must be purchased with bore and O.D. coding

Example:

To use SSR-2 bearing in a potentiometer the shaft diameter should be .1250 -.0001 to .1250 -.0003 or .1249 to .1247. The housing should be .3750 +.0002 to .3750 -.0000 or .3752 to .3750
