The role of various sealing rings

Release time2021-10-25Popularity:100

1. V-shaped sealing ring is a kind of elastic rubber sealing ring acting axially, used as a pressureless seal of the rotating shaft. The sealing lip has good mobility and adaptability, can compensate for larger tolerances and angle deviations, can prevent internal grease or oil from leaking outward, and can also prevent external splashing or dust from intruding.

2.O-shaped sealing ring is mainly used for static sealing and reciprocating sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. The V-shaped sealing ring is generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle for sealing.
