4. FAQ

Q: What materials compose the primary dynamic sealing parts of this motor grader cylinder seal kit?
A: The core piston and rod seals adopt pine fiber reinforced HNBR elastomer. This kit contains PU dust wiper rings, vanadium additive filled PTFE wear strips and POM back-up rings matching all standard sealing grooves of grader steering cylinders.

Q: How can buyers differentiate each sealing component by outward appearance?
A: HNBR main seals are low-gloss dark black with fine tight texture; PU wiper rings are orange brown; PTFE wear strips are snow white; POM back-up rings are charcoal grey. All components are precisely formed with smooth rounded edges.

Q: What movement characteristics and construction conditions is this cylinder seal kit developed for motor grader steering cylinders?
A: This set of seals adapts to continuous left and right steering movements of the grader. It prevents hydraulic oil leakage and blocks sediment when carrying out highway paving, slope trimming and open-area ground leveling projects.

Q: What temperature range supports stable long-duration operation of the whole sealing assembly?
A: Applicable working temperature ranges from -88°C to 384°C. It fits cold season highway maintenance and all-day leveling construction under high-temperature outdoor road sites.

Q: Can this seal kit be universally installed on hydraulic cylinders of all engineering machinery?
A: It adopts exclusive dimensional specifications for large motor grader steering cylinders. It cannot be applied to wheel loader tilt cylinders, excavator boom cylinders or road roller drive cylinders of other machine types.

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.
