How to choose the sealing ring according to the shaft?
General hardness is chosen according to pressure, low pressure with low hardness material, high hardness with high pressure. According to the load type can be divided into static seal and dynamic seal. According to the sealing use, can be divided into hole seal, shaft seal and rotating shaft seal
The selection of the sealing ring is mainly based on the service temperature, hardness and working medium of the material, as well as the size of the installation shaft and the form of sealing.
According to the installation form can be divided into radial installation and axial installation. Therefore, the selection of sealing ring specifications depends on the specific circumstances. For example, for static seals, H8/f7 tolerances can be used. Please choose the O type pressure ring deformation of large size as far as possible.
