PB SERIES – RPB SERIES
• The PB series provides the advantages of ball bearings
at an economical price.
• They are used for light-duty applications.
• The PB series consists of a two-piece separable zincplated
steel housing with a spherical bearing seat. This
allows the spherically ground bearing to have initial H 2 A
self-alignment in all directions.
• The ball bearing is an RA-RRB extended inner-ring-type
with positive-contact, land-riding seals and a selflocking
collar.
• The series incorporates an improved shroud-cap
design and comes permanently prelubricated.
• RPB has the same construction as the PB-type, but
with a thick, electrically conductive rubber inner liner.
• The bearings in the RPB unit are designated as RA-RRB
FS450 and have a special ball and race finish for quiet
operation.
• The RABR unit consists of the bearing with the rubber
interliner.

Housing thrust rating is 1 / 3 of housing radial load rating. Maximum suggested speed is 2400 RPM.
NOTE: Shaft diameter with an S = smaller housing.
NOTE: Load ratings are upright mounted capacities with load direction toward base.
NOTE: These units should not be mounted vertically or upside down.
