Radial Insert Ball Bearings
Radial insert ball bearings are single row, rady-to-fit units
comprising a solid outer ring, an inner ring extended on one or both
sides, cages made from plastic or sheet steel and P, R, L or T seals.
Bearings with an inner ring extended on both sides undergo less tilting
of the inner ring and therefore run more smoothly.
The outer ring has a crowned or cylindrical outside surface. In
conjunction with an INA housing matched to the bearing type, bearings
with a crowned outside surface compensate for shaft misalignments; see
Compensation of misalignments.
