Installation dimensions and selection
Series reference drawing: d is the bearing bore, OD is the wheel diameter and L is overall axial width. Use the 4 x 22 x 50 mm values in this model table. The illustration is a family construction reference; request a dimensioned approval drawing for the final assembly.
Check the 4 mm shaft fit and the available 50 mm axial space, including spacers and retention hardware.
Confirm the 22 mm contact diameter against the mating track, workpiece or guide surface.
Specify operating load, rolling speed, duty cycle, temperature and contamination before confirming suitability.
Confirm the bearing closure and any lubrication or clearance requirements for the order.
