    Inner Rings内环

    20132251513987602 Inner rings are made from hardened rolling bearing steel and have precision machined or ground raceways.内圈由硬质滚动轴承钢制成,并具有精密加工或磨削的滚道。

    They are used where:它们用于:

    The shaft cannot be used as a raceway with needle roller and cage assemblies, drawn cup needle roller bearings with open ends, drawn cup needle roller bearings with closed end and needle roller bearings.轴不能用作带滚针和保持架组件的滚道,带开口端的冲压外圈滚针轴承,带封闭端的冲压外圈滚针轴承和滚针轴承。

    needle roller bearings must be combined with wider inner rings in order to facilitate axial displacement of the shaft in relation to the housing.滚针轴承必须与更宽的内圈组合以便于轴相对于壳体的轴向位移。

    optimum running surfaces are required for the seal lips.密封唇需要最佳的运行表面。

    Inner rings, precision machined内圈,精密加工

    In inner rings IR, the raceway is precision machined.在内圈IR中,滚道是精密加工的。 Chamfers on the end faces allow easy insertion into the bearings and prevent damage to the seal lips of the bearings.端面上的倒角可以方便地插入轴承,并防止损坏轴承的密封唇。 The inner rings are available with and without a lubrication hole.内圈可带和不带润滑孔。

    Inner rings, ground内圈,地面

    In inner rings LR, the raceway is ground.在内圈LR中,滚道是磨削的。 The end faces are turned and the edges are broken.端面转动,边缘断裂。 These rings have larger tolerances than the rings of series IR.这些环比IR系列环具有更大的公差。 They are therefore suitable for applications that permit larger tolerances for width and less demanding requirements for axial runout.因此它们适用于宽度较宽和轴向跳动要求较低的应用。
