Bearings without an inner ring are highly suitable for bearing arrangements with particularly compact radial dimensions, if the shaft raceway can be hardened and ground. If no inner ring is used, the shaft can be designed to a greater thickness and thus with increased rigidity. If the shaft raceway is produced to the appropriate dimensional and geometrical accuracy, bearing arrangements with increased running accuracy can be achieved.

Due to their special technical features, needle roller bearings are highly suitable for bearing arrangements in: Printing Machinery, The Food and Packaging Industry, Compressors, Fluid and Hydraulic Pumps, Automotive Chassis and Gearboxes, Gearboxes for Industrial, Rail and Wind Turbine Applications, Agricultural Vehicles and Equipment.
