SKF HK 4012 Needle Roller Bearing

SKF needle roller bearings pack long, small-diameter rollers into a very thin radial section, delivering more load capacity per millimetre of envelope than any other rolling bearing type. They are the answer whenever the housing bore or shaft diameter is fixed and there is simply no room for a conventional roller bearing. The NK series runs without an inner ring, so the needles roll directly on the shaft, provided it is hardened and ground to raceway quality, freeing several millimetres of cross-section; NKI and the NA 48, 49 and 69 series add a removable machined inner ring for shafts that cannot be prepared, while the matching RNA versions omit it again for maximum compactness. HK drawn cup bearings use a thin pressed outer shell that press-fits and self-retains in an unmachined housing bore, suiting high-volume, cost-sensitive designs. Typical stocked designations include NK 25/20, NA 4905 and HK 2520, all made to ISO boundary dimensions and interchangeable with equivalent metric references. In the Kingdom they serve automotive transmission and driveline repair, packaging and printing lines, planetary gear pins and lever linkages where machine builders in Riyadh, Dammam and Jeddah need maximum capacity in minimum space.
