这种接触式密封件一般对设备各项配合尺寸精度要求很高，否则以投入运行就会造成不同程度的渗油，随着配合间隙的增大，漏油更加严重，不能 设备长期处于运行稳定状态。

更大的弊端是长时间运转对配合轴位置有一定的磨损，形成深浅不一的小沟槽，即使更换新的密封也不能 解决泄漏，特别是活动辊侧的减速机振动大，密封唇口的追随性不是很好，更易产生油的泄漏。

This kind of contact seal generally has high requirements for the precision of the matching dimensions of the equipment, otherwise it will cause different degrees of oil seepage to be put into operation. With the increase of the matching gap, the oil leakage is more serious, and the equipment cannot be in a stable state of operation for a long time.

The bigger disadvantage is that the long-term operation has a certain wear on the position of the matching shaft, forming small grooves of different depths, even if the replacement of the new seal can not solve the leak, especially the reducer vibration on the side of the active roller is large, the tracking of the seal lip is not very good, and it is easier to produce oil leakage.
