Rolling Mill Bearings
Rolling bearing can be classified by the tolerance and rotating accuracy grade
Radial bearings (except tapered roller bearings) tolerance class is divided into
five levels- 0, 6, 5, 4 and 2, , the accuracy grades are from low to high order.
Tapered Roller Bearing tolerance class is divided into four levels- 0, 6X, 5
and 4, the accuracy grades are from low to high order.
Thrust bearing tolerance class is divided into four levels 0, 6, 5 and 4, the
accuracy grades are from low to high order.
Specific tolerances and rotating accuracy grade. See GB/T307 standards.

自由运动球螺杆和螺母滚珠丝杠之间转让力和运动。这种转移明智取代传统的直接函数明智螺杆和螺母之间。因此最低滚动摩擦代替滑动摩擦的传统滚珠丝杠。滚珠丝杠副的传输效率将达到 90%以上。传质单元的驱动力矩将减少到 1/3 的滑动螺钉。这很大程度上降低了热率。...
