explain In the hydraulic cylinder, the dust ring is placed on the piston rod and plunger that move axially. During the movement of the piston rod and plunger, if dust enters the hydraulic cylinder, it can cause leakage Premature wear of sealing and supporting rings. H32 dust ring can effectively prevent dust Dust enters the hydraulic cylinder. advantage Even for dust that is firmly adsorbed, it has a good dust scraping effect; Wear resistant and have a long lifespan; Capable of storing and reversing residual oil The function; Using elastic materials can reduce the coefficient of friction; It is also a standard component that conforms to standard grooves. technical parameter Pressure: Dust scraping edge: Atmospheric pressure Sealing edge: ≤ 2MPa. If the pressure is high, a pressure relief hole must be set up Working temperature: -30 ℃ to+80 ℃ Reciprocal speed: ≤ 1.0m/s Medium Mineral oil, grease, and flame retardant fluid, etc Installation To ensure that the seal is not damaged during installation, Installation must strictly follow the requirements for sealing installation. Material Science High performance imported polyurethane (TPU), Shore hardness (SHA) 93 °
