Piston Bore Seals

Ruichen Seals' square combination seals for pistons (bore) are designed for bidirectional pressure sealing in reciprocating hydraulic motion. The Glyd Ring Seal uses O-rings to continuously provide radial force and automatically compensate for wear, ensuring long-lasting and stable sealing performance. It features low friction, high pressure resistance, and excellent dynamic response. Used in conjunction with a guide ring, it is an ideal sealing solution for heavy-duty hydraulic cylinders and precision equipment.
