Dust ring applied to the hydraulic pneumatic piston rod, the main role is to remove the external surface of the piston cylinder adhered to the dust, prevent sand, water and pollutants into the sealed cylinder.
Notes for use of dust proof ring: all dust proof ring cannot bear pressure, that is, it does not have a sealing function, its role is only dust proof, must be used with other seals; During the design, the lip of the dustproof ring should be avoided to come into contact with the piston rod hole or the opposite side of the spanner, so as to avoid being cut.
