  • Piston Seal

    Piston Seal

    Piston seals maintain sealing contact in sliding motion between the piston and cylinder bore for hydraulic and pneumatic equipment.
    The piston seal is a shaft seal, and the piston rod seal is a hole seal. The oil cylinder is composed of a cylinder block, a piston, a piston rod, a cylinder head and a sealing ring. When using a piston seal, it can be used in combination with an anti-pollution seal to prevent damage due to foreign matter or adiabatic compression, which can improve durability.

  • Guide/Wear Ring

    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.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. 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.

  • Back Up Ring

    Back Up Ring

    Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. They also compensate for large temperature fluctuations. Back up ring including BRT, N4W. Hydraulic cylinder seals prevent the leakage of working medium (internal and external leakage) and prevent foreign objects (such as air, dust and water) from entering the hydraulic components and hydraulic system.
