Drawn cup needle roller bearings

Product tables …………………………………………………………………………… page 56 SKF drawn cup needle roller bearings, as the name suggests, are needle roller bearingswith a deep drawn thin-walled outer ring withopen or closed end. They are characterisedby very low sectional height and high loadcarrying capacity. They are used when the housing bore cannot be used as a racewayfor a needle roller and cage assembly butwhere a very compact and economic bear-ing arrangement is required. They are pres-sed into the housing bore and, if shouldersor retaining rings are not required for axiallocation, the design of the housing bore is simple and can be economically produced. Drawn cup needle roller bearings are avail-able with open ends ( âž” fig
1 )or with closedend ( âž” fig
2 ). The latter are suitable for bearing arrangements at the ends of shafts.The profiled design of the closed end alsopermits small axial guidance forces to be accommodated.
