The importance of bearing seals

Sealing parts are extremely important for bearings. If there is a problem in the sealing part, the pressure on the bearing sealing test is very high, especially for the pressure test without a rod cavity. As a result, this type of pressure test is usually carried out after carefully assembling the cylinder before entering the commissioning stage of the assembly machine. The bearing sealing test is based on the assembly and reliability assessment of the seal part and joint of the assembled cylinder, such as cylinder nozzle sealing and connection, cylinder piston up, static seal and sealing condition, etc.
