轧机备用滚子轴承

Based on many years of experience and recorded success in the area of multi-roll mills,Jiayu  supplies high-durability,high-precision cylindrical roller bearings for backing shafts(backing bearing).

背衬轴承有多种设计和变型。主要产品是双列或三列圆柱滚子轴承。此外，还有单列滚针轴承和双列圆锥滚子轴承。

Our backingup bearing are mainly used to roll Silicon plate or sthin-section steel plate. These bearings have a particularly thick-walled outer ring and can be mounted on stationary support shafts to form backup or straightening rolls. Our backing bearings are used on the eight support shafts of a 20-roll mill.

高度差可以达到 0.005 毫米，甚至 0.0025 毫米。

维护和返工

辊子中间的支撑轴承比辊子两端的轴承承受更大的负荷。由于中间轴承的磨损比其他轴承大，因此应更频繁地更换。

重新加工后，必须对外圈进行清洁、重新测量、标记，并与适当的滚子互补件或滚子和保持架组件以及内圈重新组装，以形成完整的背衬轴承。此外，还必须重新划分截面高度组。
