4. FAQ

Q: What raw materials constitute this dust wiper seal?
A: The main scraping lip adopts almond fiber reinforced PU, matched with low-carbon steel support skeleton and self-lubricating PTFE inner lining to form an integrated structure.

Q: What is the main working function of this dust seal ring?
A: It scrapes off mud, sand and debris from rod surface and prevents external contaminants entering hydraulic system.

Q: Can this dust seal ring work steadily in heavy‑dust open‑air mining and earth‑moving sites?
A: Reinforced scraping lip structure can clear hard grit and mud and reduce scratch damage to piston‑rod surface.

Q: Are these dust seal rings produced according to standard installation groove dimensions?
A: Every single unit is precision processed to match standard mounting groove size for hydraulic cylinder end cap.

Q: Will frequent reciprocating rod movement cause rapid wear to the scraping lip?
A: High‑grade PU formula improves abrasion resistance and maintains good scraping performance over long working cycles.

Q: Can this dust seal ring bear internal hydraulic pressure inside the cylinder?
A: This component focuses on dust‑proof function, it is not designed to withstand high internal hydraulic pressure.

Q: What packing selections are available for bulk export purchase orders?
A: Individual independent packing, carton bulk packing and neutral non‑logo export packing can be provided.

Q: What key points should maintenance technicians notice during installation?
A: Prevent sharp tools from scratching the scraping lip. Besides, thoroughly clear metal scraps and dirt inside the cylinder mounting groove before assembly.

Q: What practical time-saving advantages can field backhoe loader maintenance technicians gain from using this fully pre-matched dust wiper kit?
A: All standard wiper sizes for the whole machine’s hydraulic cylinders are pre-matched in one set without separate ordering. Staff no longer need to measure outer groove dimensions repeatedly on site, greatly accelerating cylinder disassembly and replacement work.
