5. FAQ

Q: What raw materials make up this piston seal ring assembly?
A: The primary sealing ring adopts poplar fiber reinforced HNBR elastomer, equipped with silicon filled PTFE sliding ring and rigid modified POM back-up ring for matching assembly.

Q: What color can customers observe for this sealing component?
A: The main sealing ring is light brown, and the inner elastic energizer is dark black.

Q: Where is this piston seal ring assembled on equipment?
A: It is installed inside piston groove of bucket hydraulic cylinder, preventing hydraulic fluid bypass and maintaining stable cylinder working pressure.

Q: Can this seal ring withstand frequent loading and impact during material handling work?
A: Yes, it can handle cyclic pressure surges and reciprocating friction during bucket shoveling, lifting and dumping cycles.

Q: Does each single seal ring include matching auxiliary sealing accessories?
A: Yes, each piece comes with corresponding elastic energizer for complete piston sealing assembly.

Q: What temperature range can this piston seal ring keep stable sealing performance?
A: Reliable working performance ranges from ‑25℃ up to 138℃ under variable outdoor construction‑site environment.

Q: What hydraulic malfunctions can this piston seal ring effectively prevent?
A: It inhibits internal hydraulic oil leakage inside the cylinder and prevents seal deformation caused by pressure difference on two sides of the piston.

Q: What prominent strengths does poplar fiber reinforced HNBR have compared with conventional rubber materials?
A: It has excellent shock resistance and stable compression resilience, adapting to frequent angle adjustment movement of grader tilt cylinders.

Q: What engineering projects commonly require replacement of this piston seal ring?
A: It serves routine maintenance of hydraulic cylinder piston sealing assemblies on medium crawler excavators, widely used in urban infrastructure, highway subgrade construction, small quarry loading and residential foundation excavation projects.
