Description
This Rod Buffer Seals Ring is used to absorb shock and fluctuating pressures under high loads, isolate high-temperature fluids and improve the durability of the packing. It has small frictional resistance and is suitable for high-speed, short-stroke operation. The slit on the tapered surface can leak backpressure. HBTS is a standard double-acting seal. Suitable for reciprocating motion, allowing for larger extrusion gaps for a wide range of applications.
The Rod Buffer Seals Ring has an excellent dynamic and static sealing performance, able to work in a dusty environment. Low friction, simple groove, and strong adaptability to working conditions. It is suitable for reciprocating hydraulic systems and performs excellent under high, low pressure, and high-frequency conditions. Furthermore, this seals ring is suitable for long and short strokes. Suitable for large rod diameters in fluids and high pressures, such as bulldozers, compressors, etc.
