Needle roller bearings without an inner ring are an excellent choice for compact bearing arrangements if the shaft can be hardened and ground. Eliminating the need for a separate inner ring enables a larger shaft diameter and a stiffer bearing arrangement. Axial displacement of the shaft relative to the housing is only limited by the width of the raceway on the shaft. By machining the shaft raceways to the appropriate dimensional and geometrical accuracy, it is possible to obtain bearing arrangements with heightened running accuracy. This Bearing can be used in a wide of industries such as lifting equipment, agricultural, pumps, air conditioning units, fans and general engineering applications.

Inner Rings are made of rolling bearing steel and after hardening there bores, raceways and end surfaces are ground. Metric series inner rings may be used to provide inner raceway surfaces for metric series radial needle roller bearings and metric series drawn cup needle roller bearings.

Whenever the shaft can be used as the inner raceway, needle roller bearings without inner rings provide advantages of economy and close control of radial internal clearance in operation. Tolerance class F6 is the normal specification for the metric series needle roller complement bore diameter of an unmounted bearing.
