对托辊轴承做好定期维护保养(定期检查)，可以使托辊配件轴承充分发挥并长期保持其应有的性能。

Periodic maintenance (periodic inspection) of roller bearings can make full use of and maintain their proper performance for a long time.

1、托辊轴承的检查与判断

1. Inspection and judgment of roller bearings

为了判断拆下的轴承能否重新使用，要着重检查其尺寸精度、旋转精度、内部游隙以及配合面、滚道面、保持架和密封圈等。

In order to judge whether the removed bearing can be reused, it is important to check its dimensional accuracy, rotation accuracy, internal clearance and mating surface, raceway surface, cage and sealing ring.

关于检查结果，可由用惯轴承或精通轴承者进行判断。

The results of the inspection can be judged by those who are familiar with the conventional bearings or those who are proficient in bearings.

判断的标准根据机械性能和重要度以及检查周期等而有所不同。如有以下损伤，轴承不得重新使用，必须更换。

The criteria for judgment vary according to the mechanical performance and importance, as well as the inspection cycle. If the following damage occurs, the bearing shall not be reused and must be replaced.

1) 托辊配件轴承零部件的地变电阻柜 精密铸造 中频电炉设备 保定断桥铝门窗 保定养老院 镜子批发 启闭机断裂和缺陷。

1) Fracture and defect of bearing parts of idler fittings.

2) 滚道面物滚动面的剥离。

2) stripping of rolling surface of raceway surface.

2、清洗

2, cleaning

将托辊配件轴承拆下检查时，先用摄影等方法做好外观记录。另外，要确认剩余润滑剂的量并对润滑剂采样，然后再清洗轴承。

When disassembling and inspecting the bearing of supporting roller fittings, the appearance record should be made by photography first. In addition, it is necessary to confirm the amount of residual lubricant and sample the lubricant before cleaning the bearing.
