If the tolerances are unfavourable, the yoke type track roller should be pressed onto the shaft or stud using a press. The inner ring must be fitted such that the pressing-in force is distributed uniformly on the end face of the inner ring.

The INA bearings should be fitted such that the lubrication holes are positioned in the unloaded zone. For yoke type track rollers PWTR and NNTR, there is no need for defined positioning of the lubrication hole.
