The
TFG-Type backup ring, also known as a support ring, is an essential auxiliary hydraulic sealing accessory designed to prevent seal extrusion and deformation under high-pressure working conditions. Manufactured from high-rigidity, wear-resistant engineering plastic materials, the TFG support ring delivers outstanding extrusion resistance, low friction and stable dimensional durability, perfectly cooperating with piston and rod seals in heavy-duty hydraulic systems.
During high-pressure and impact load operation, ordinary seals are prone to being squeezed into assembly gaps, resulting in leakage and early failure. The
TFG-Type backup ring features a precise structural design that effectively fills groove clearances, firmly supports the main sealing ring and limits excessive deformation. It greatly improves the pressure resistance of the whole sealing assembly and avoids seal damage caused by pressure surge and gap extrusion.
With excellent temperature adaptability and hydraulic oil compatibility, the
TFG backup ring works stably in various industrial hydraulic environments. It fits standard seal grooves for easy installation and replacement. Widely applied in construction machinery, hydraulic cylinders, mining equipment and lifting machinery, it effectively extends seal service life, reduces system failure rate and cuts long-term maintenance costs for hydraulic equipment.
