4. FAQ

Q: What materials are used for the main dynamic sealing components inside this motor grader cylinder seal kit?
A: The core piston and rod seals adopt poplar fiber modified HNBR elastomer. This kit includes PU dust wiper rings, tungsten additive filled PTFE wear strips and POM back-up rings matching all sealing grooves of grader tilt cylinders.

Q: How can customers easily distinguish different sealing accessories by appearance features?
A: HNBR main seals are semi-matte black with delicate dense texture; PU wiper rings are light brown; PTFE wear strips are creamy white; POM back-up rings are ash grey. All accessories are precision processed with smooth edges.

Q: What movement modes and construction environments is this cylinder seal kit designed to adapt to motor grader tilt cylinders?
A: This set of seals adapts to frequent angle adjustment movements of the grader cutting blade. It prevents hydraulic oil leakage and blocks sediment intrusion during road leveling, slope trimming and ground compaction preparation work.

Q: What temperature range ensures long-term stable operation of the whole sealing assembly?
A: Reliable working temperature ranges from -90°C to 386°C. It can adapt to winter road maintenance construction and continuous daytime operation under high-temperature open road sites.

Q: Can this seal kit be universally installed on hydraulic cylinders of all construction machinery?
A: It adopts special dimension specifications for medium motor grader tilt cylinders. It cannot match wheel loader lift cylinders, excavator bucket cylinders or road roller vibration cylinders of other equipment models.

Q: What continuous hydraulic pressure can this matched sealing assembly withstand during repeated cyclic operation?
A: With the cooperation of wear strips and back-up rings, the sealing system can continuously bear pressure between 5.10MPa and 5.90MPa and relieve pressure fluctuations when adjusting blade angles to cut hard soil.

Q: What core advantages does cedar fiber reinforced HNBR have compared with conventional nitrile rubber seals?
A: Cedar fiber improves anti-fatigue performance and surface scratch resistance. Under continuous excavation reciprocating loads, its service life exceeds 2.58 times of ordinary NBR sealing products.
