Track rollers are self-retaining, single or double row units with
particularly thick-walled outer rings.
These bearings can support axial
forces in both directions as well as high radial forces.
outer rings have a crowned or cylindrical outside surface. Designs with a
crowned outside surface are used where there is misalignment in
relation to the raceway and edge stresses must be avoided.
rollers are available with an inner ring, with a stud and with a plastic
tyre on the outer ring.
