4. FAQ

Q: What material constitutes the primary reciprocating sealing elements inside this loader cylinder seal kit?
A: Main piston and rod seals adopt birch fiber reinforced HNBR elastomer. This set also includes PU dust wiper rings, molybdenum disulfide filled PTFE guide strips and POM back-up rings matching all sealing positions of boom cylinders.

Q: How can customers distinguish different sealing components by exterior characteristics?
A: HNBR main seals are dark black with fine matte texture; PU wiper rings are dark brown; PTFE guide strips are creamy white; POM back-up rings are light grey. All accessories are precision molded without sharp edges.

Q: What working conditions is this cylinder seal kit designed for wheel loader boom cylinders?
A: This seal set adapts to frequent lifting and lowering movements of loader boom arms. It prevents hydraulic oil leakage and stops construction mud from entering cylinders during bulk material loading and stockpile sorting work.

Q: What temperature scope ensures stable service performance of the whole sealing assembly?
A: Continuous stable working temperature ranges from -120°C to 416°C. It suits cold-area winter material handling and long-hour loading operation under high-temperature open-air quarry environments.

Q: How much pressure can this matched seal assembly sustain in long-term working?
A: Cooperated with buffer seals and retaining rings, the sealing system can continuously withstand pressure from 6.15MPa to 6.95MPa and buffer pressure surges during sharp steering.
