4. FAQ

Q: What material constitutes the primary sealing structure of this piston rod seal?
A: The main sealing body adopts hawthorn fiber reinforced HNBR elastomer, matched with manganese filled PTFE wear-resistant ring and rigid POM backup ring for assembly.

Q: What visual color features do these sealing components have?
A: The main rod seal presents semi-gloss black, the PTFE support ring is off-white, and the anti-extrusion ring appears ash grey.

Q: Can this piston rod seal be installed on hydraulic cylinders of different construction equipment?
A: It is specially tailored for excavator swing cylinders. It cannot be fitted on loader tilt cylinders or grader lift cylinders of different dimensions.

Q: Which construction environments fit this hydraulic piston rod seal well?
A: It works reliably at foundation construction and quarry sites, coping with continuous rotary reciprocating motion and dust contamination.

Q: How about the temperature adaptability of this whole sealing assembly?
A: It can operate steadily between -79°C and 374°C and maintain consistent sealing performance under long-time rotary heavy loads.

Q: What preparation should technicians finish before mounting this rod seal?
A: It is essential to clean the cylinder interior thoroughly. Residues inside will scratch the sealing lip and shorten service life greatly.

Q: What practical efficiency benefits can on-site excavator maintenance staff gain from using this fully pre-matched rod seal kit?
A: All supporting sealing accessories required for rod overhaul are pre-assembled into one complete set without separate procurement. Technicians do not need to carry scattered loose seals or repeatedly measure rod groove dimensions on site, greatly shortening cylinder repair time.
