    Guide/Wear Ring

    Wear ring or guide ring is used as bearing of rod and piston to prevent its scoring or accentricity and to improve the durability of the packing. Wear ring effect The wear ring is used as a supporting element on the piston to prevent the piston and the cylinder from scratching each other, reduce the eccentricity, and improve the durability of the seal. Selection of wear ring The shape and material of the wear ring should be selected according to the working conditions. Like the oil cylinders for construction equipment, at low speeds and high loads, phenolic resin and WR containing resin fibers are used. For high speed, low load, or creeping, please use polytetrafluoroethylene resin model RYT or RYT2 with excellent friction and abrasion characteristics. The material of RYT is polytetrafluoroethylene resin, which is characterized by a low friction and wear ring without creeping. Excellent wear resistance in high speed and low load areas. We calculate by volume and can cut according to the size of the cylinder bore. Can withstand temperatures ranging from -55 degrees Celsius to 220 degrees Celsius.
