What is the importance of SKF bearing seals?

Seals are extremely important for SKF bearings, if there is a problem in the sealing part, it will have a great impact on the bearing, such as irregular shape, lack of meat, small cracks and other defects of the seal are not acceptable. However, the sealing test of SKF bearings is the assessment of the assembly and working reliability of the assembled cylinder seal parts and their joints. Such as the seal and connection of the cylinder head, the upward movement of the cylinder piston (between the rod cavity and the rodless cavity), the static seal and the sealing condition.
The pressure of SKF bearing sealing test is very large, especially for the pressure test without the rodless chamber, if there is no tooling to bear, the pressure test by the rodless chamber and the piston acting on the piston rod is very large, if only by the connection of the cylinder head to bear. Therefore, usually this type of pressure test is carried out after careful assembly of the cylinder before entering the debugging stage of the final assembly machine.
When using the frame of the machine the cylinder belongs to to withstand great pressure, it is OK if the cylinder is well assembled. The cylinder will be very smooth in the final assembly pressure test, which will not only save the equipment of separate pressure test after the cylinder assembly, but also save the corresponding working hours, but also shorten the production cycle, which is very useful for the production effect. If the operator does not carefully check and work carefully, it will not pay for the results.
Therefore, before assembling SKF bearings, the dimensional accuracy of relevant parts should be carefully checked, and the sealing part will fail due to the dimensional accuracy of the sealing groove or the roughness of the sealing surface does not meet the requirements. In addition, it is especially necessary to check the sealing lip, and defective seals cannot be installed into the product. In addition, the material, hardness and other indicators of SKF bearing seals should be checked against the product certificate and the warehouse receipt.
