Problems easily presented by rollers

by:Laike     2020-07-21
A. Wheel body wear. The reason for this situation is that the steel used is unqualified or that the hardness of the material during heat treatment is low and the wear resistance is lacking;

B. Oil leakage. The roller axle continuously rotates through the shaft sleeve, and the wheel body needs to be lubricated to smooth, but if the sealing ring is not good, it is easy to produce oil leakage, so that the shaft and the sleeve are easy to wear without smooth conditions. Formed products cannot be stopped.

There are several reasons for oil leakage:

1 floating oil seal failed

2. The roundness of the product sleeve is not enough

3. Support shaft gloss is not enough

4. Gear oil does not meet the standard

5. The problem of machining dimensional tolerances, etc. will cause the situation of roller oil leakage.
