HBY

The main material of HBY is polyurethane, which is mainly used in petroleum-based hydraulic oil; the HBY buffer ring can relieve the impact pressure generated on the piston rod side of the hydraulic cylinder, relieve the back pressure, and prevent the oil temperature from being directly overheated to the oil seal, resulting in deterioration of the oil seal. , Play the role of cushioning and slightly cooling down, reducing the frictional resistance of the oil seal and the problem of sliding heat during the movement of the oil cylinder.
