Ball BeaRIngs
PB SERIES - RPB SERIES
• PB Series provides the advantages of ball bearings at an
economical price.
• Used for light-duty applications.
• Consists of a two-piece separable zinc-plated steel housing
with spherical bearing seat. This allows the spherically ground
bearing to have initial self-alignment in all directions.
• The ball bearing is a RA-RRB extended inner ring type with
positive contact land-riding seals and a self-locking collar.
• Incorporates improved shroud cap design and comes
permanently prelubricated.
• RPB has same construction as PB-Type, but with a thick,
electrically-conductive rubber interliner.
• Bearings in the RPB unit are designated as RA-RRB F-450 and
have a special ball and race finish for quiet operation.
• RABR unit consists of the bearing with the rubber interliner.
Suggested shaft tolerances: nominal to -.013 mm, -.0005”.

(1) Housing thrust rating is 1 /3 of housing radial load rating. Load ratings are upright mounted capacities with load direction toward base.
These units should not be mounted vertically or upside down.
Shaft diameter with an S = smaller housing.
