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 core job does this dust seal ring undertake during machine operation?
A: It wipes away mud, dust and fine gravel sticking on rod surface and stops outside pollutants entering cylinder interior.
Q: Is this dust seal ring suitable for muddy construction working conditions?
A: The sharp‑edged scraping lip can peel off sticky mud, lowering abrasive damage to piston rod surface effectively.
Q: Are these dust seal rings produced following standard installation groove specifications?
A: Each piece is precision sized to fit the standard groove dimension of excavator hydraulic cylinder end cover.
Q: Will repeated back‑and‑forth rod movement make the scraping lip wear out quickly?
A: Modified PU material enhances wear resistance, so the lip can keep good wiping performance for long working hours.
Q: Can this dust seal ring hold back high hydraulic pressure inside the hydraulic cylinder?
A: It only serves for dust exclusion; it cannot bear the high working pressure from internal hydraulic oil.
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.
