Forged Rings for Slewing Rings

We can also provide Forged Rings for Slewing Rings . We can supply the material of C45 steel, 50Mn, 42CrMo material. Normally we deliver the forged rings after rough machining and quenching, and the tolerance can be discussed case by case.

We determine the hardness according to the diameter of depression in the forged rings.

角接触球轴承有滚道的内圈和外圈，彼此流离失所的轴承轴方向。

由于其高的极限速度和极低，在整个速度范围内，均匀摩擦力矩这些轴承是特别适合结合转矩。

ZKLDF 是低摩擦、高精度非常高的速度，高的轴向和径向负荷和倾动刚度高的要求。这些轴承是特别适合精密应用涉及组合的载荷。他们首选的应用领域包括轴承安排在回转工作台和珩磨头以及测量和试验设备。...
