Stud type track rollers
Stud type ball bearing track rollers are ready-to-fit, single or double row rolling bearings based on deep groove or angular contact ball bearings.
They have particularly thick-walled outer rings with a crowned outside surface (also available with a cylindrical outside surface on request), can support high radial loads and tolerate axial loads which are due to small misalignments, skewed running or temporary contact running impacts.
Instead of an inner ring, stud type ball bearing track rollers are supplied with a heavy-section roller stud with fixing thread. They are not mounted in a housing bore but supported on a flat raceway (mating track).
In the design with an eccentric collar, stud type ball bearing track rollers can be adjusted to the mating track. As a result, larger manufacturing tolerances can be tolerated, for example, in the adjacent construction.
Stud type ball bearing track rollers are sealed.
