Carries radial loads in a compact cross-section thanks to needle rollers guided directly on a machined inner ring, which forms an integral part of this needle roller bearing. Bore diameter is 28.0 mm, outside diameter 42.0 mm, width 30.0 mm, mass 0.145 kg. Limiting speed reaches 14000 1/min, with a reference speed of 7600 1/min, and the design belongs to the light NKI series. Radial internal clearance is set to CN (Group N), giving standard running clearance suited to normal fits and moderate temperature conditions without additional adjustment. The standard cage guides the needle rollers evenly around the raceway, supporting stable operation at the rated speeds. As the inner ring is machined into the bearing itself, mounting requires a shaft seat matched to this ring, and separate lubrication (grease or oil) must be provided according to the operating speed and load.
