5. FAQ
Q: What role does silicon-doped PTFE play when cooperating with main sealing parts?
A: Silicon additives optimize the lubricity and compression stability of PTFE. It perfectly fills tiny gaps in piston grooves. When the loader turns sharply or lifts heavy materials to generate instant pressure spikes, it buffers impact pressure effectively and prevents the PU seal lip from being squeezed, deformed or damaged, while lowering overall operational friction.
Q: What makes weatherproof NBR stand out from ordinary rubber materials?
A: This upgraded NBR integrates excellent oil resistance, ozone resistance and moisture resistance. It can stay stable under long-term oil immersion, damp air and alternating sunshine and rain. It will not harden, crack or lose elasticity easily, fully adapting to changeable outdoor working environments all year round.
Q: Where are the weatherproof NBR seals mainly mounted on the hydraulic cylinder?
A: These rubber components are mostly installed on fixed connecting positions, including cylinder end cover joints, flange surfaces and thread connectors of auxiliary hydraulic pipelines. These areas are exposed to hydraulic oil and outdoor humidity for a long time, giving full play to the material’s comprehensive weather resistance.
Q: How does the woven composite phenolic guide ring assist the reciprocating piston?
A: This guide ring can offset the lateral force caused by unbalanced loading and steering resistance. It corrects minor radial deviation of the piston, keeps it moving along the central axis steadily, and minimizes direct metal friction. This design slows down component wear and ensures the cylinder operates smoothly and stably for a long time.
Q: Are all sealing parts manufactured in line with original equipment size standards?
A: Every seal, backup ring and guide ring is strictly produced according to OEM technical specifications and groove dimensions. All components match the original installation positions precisely, so no structural modification to the cylinder is required during replacement.
Q: Do maintenance workers need to cut, grind or stretch seals for fitting during on-site installation?
A: No secondary processing is required at all. After removing worn and aged old seals, new parts can be directly installed into standard grooves. The pre-adjusted assembly tightness is proper, which simplifies installation procedures and improves field maintenance efficiency.
