SKF bearing seal - bearing the importance of knowledge

Seal is extremely important for SKF bearing, if sealing parts problems will cause great impact on bearing, such as irregular shape, short of tiny crack defects such as meat, the seal is not possible.
SKF bearing sealing test, however, are all on the assembly after the oil cylinder sealing parts and assessment of the reliability of the joint assembly and work.
Crock mouth seal and connection such as cylinder, cylinder piston (
There are no bar and rod cavity)
The dynamic and static seals and sealing condition, etc.
SKF bearing the leakage test pressure is very big, especially for the rodless cavity pressure test, without tooling, by the rodless cavity pressure testing and through a lot of pressure acting on the piston rod, piston, if only the connection to withstand oil crock mouth is absolutely not.
Therefore, this type of pressure testing is usually after carefully oil cylinder assembly, to enter assembly machine commissioning phases.
When using the oil cylinder, belongs to the machine frame to pressure if oil cylinder assembly is can be very good.
Oil cylinder is suitable in the assembly and testing, not only save the oil cylinder assembly after separate test fixtures, and save the corresponding working hours, also can shorten the production cycle, the production effect is very useful.
If the operator didn't checked carefully and careful work would be a pyrrhic victory.
Therefore, before the assembly SKF bearing should carefully review the parts dimensional accuracy, sealing parts due to the size of the seal groove accuracy out-of-tolerance or seal surface roughness do not meet the requirement and make the seal failure.
In addition, in particular, to examine the sealing lip, can't take the defective seal into products.
In addition, SKF bearing seal material, hardness and other indicators to check against product certificate and outbound order.
