Classification of bearing sealing ring
Dec 06, 2018

Classification of bearing sealing ring The seal can be divided into two main types,static sealing and relative movement between the static sealing and relative movement joint surface.Static seal mainly a little sealed, adhesive seal and contact seal three major categories. According to the working pressure, the static seal can be divided into middle and low pressure static sealing and high pressure seal. Middle and low pressure static sealing commonly used material is soft, bearing manufacturers the gasket is wider than the pad seal, the high pressure static seal is made of the material hard, the contact width is very narrow metal gasket. The dynamic seal can be divided into two basic types of rotary seal and reciprocating seal. According to the sealing parts of the relative movement of the seal parts are contact, can be divided into contact type seal and non-contact seal. Generally speaking, the contact seal is good, but is limited by the friction and wear, it is suitable for the sealing surface line speed is lower. Non contact sealing sealing is poor, high speed bearing suitable for higher speed occasions.
