■ 제품사양

Inside Diameter = 57mm Outside Diameter = 57mm Roller Bearing
타입 = Needle Race Width = 20mm Bore
타입 = Parallel Material = Steel Static Load Rating = 56000N
행 수 = 1 Dynamic Load Rating = 32500N End
타입 = Open Fatigue Limit Load = 10100N The Bearings can support high to very high radial forces Are used when the load carrying capacity or accuracy of drawn cup needle roller bearings with open ends is no longer sufficient and the high load capacity of cylindrical roller bearings is not yet required Can only support radial loads and, as a result, are highly suitable for use as non-locating bearings (they permit axial displacement of the shaft relative to the housing in the bearing) Permit high speeds in spite of line contact Compensate misalignments between the shaft and housing (aligning needle roller bearings) Require only a very small radial design envelope, particularly if the bearing arrangement is designed without an inner ring Are available in numerous sizes and designs Result in particularly compact, cost-effective and economical bearing arrangements
