The R-Series ball bearings, named for their numerical
model numbers, are also known as our Precision Inch Series ball
bearings. R series bearings are available in open, sealed and shielded
configurations. Sealed and shielded bearings may be slightly wider as
shown in the table.
The R-Series bearings are single row, inch series bearings
available from 1/8 through 1-1/2 inch bore sizes. The construction of
these bearings enables them to accept thrust as well as radial load.
Their ball complement and selection of retainers also allows them to
work well in high-speed applications.
