Buffer seal - HBY type

Buffer seals

 

The primary purpose of the buffer seal is to protect the main rod seal from the effects of shock pressure loading.

 

And The HBY buffer sealing ring is composed of a polyurethane main sealing ring and a polyoxymethylene retaining ring,

and is an important component of the hydraulic cylinder sealing system. Usually used in conjunction with other main seals,

this structural design allows this product to provide cushioning, compression resistance, and other functions in the oil cylinder.
