5. FAQ

Q: How can customers easily distinguish each sealing accessory by visual features?
A: HNBR main seals are matte jet black with fine compact texture; PU wiper rings are chestnut brown; PTFE wear bands are off-white; POM back-up rings are light ash grey. All accessories have smooth edges without burrs.

Q: What working conditions is this cylinder seal kit designed to adapt to motor grader steering cylinders?
A: This seal set adapts to frequent reciprocating steering actions during road construction. It stops hydraulic oil leakage and blocks external sediment when adjusting the driving direction for ground leveling and slope trimming.

Q: What temperature range can the whole set of sealing components work steadily?
A: Stable operating temperature ranges from -122°C to 418°C. It fits low-temperature road projects in alpine regions and long-time continuous work under high-temperature open-air municipal construction sites.

Q: Can this seal kit be universally installed on hydraulic cylinders of all engineering machinery?
A: It is customized according to dimensions exclusively for motor grader steering cylinders. It cannot match wheel loader bucket cylinders, excavator boom cylinders or road roller drive cylinders of other equipment types.

Q: What continuous hydraulic pressure can this matched sealing assembly bear during repeated cyclic operation?
A: Supported by wear bands and back-up rings, the sealing system can steadily withstand pressure ranging from 5.90MPa to 6.70MPa and absorb pressure shocks during frequent steering adjustment.

Q: What types of construction projects usually need this steering cylinder seal kit for routine maintenance?
A: It is widely used for overhauling motor graders working on provincial road reconstruction, industrial park site leveling, rural highway paving and large open ground renovation projects.

Q: What performance advantages does fiber modified HNBR have compared with conventional nitrile rubber seals?
A: Paulownia leaf fiber improves low-temperature elasticity and wear resistance. Under long-term reciprocating steering loads, its service life reaches more than 2.64 times that of ordinary NBR sealing accessories.

Q: How will these sealing accessories perform under long-term outdoor dusty and muddy construction environments?
A: The outer PU wiper can scrape mud and tiny gravel adhered to the piston rod surface. It lowers abrasion on the sealing lip and effectively slows down slow hydraulic oil seepage.

Q: What performance advantages does fiber-reinforced HNBR have compared with conventional nitrile rubber sealing parts?
A: Albizia leaf fiber improves low-temperature flexibility and abrasion resistance. Under repeated reciprocating loads, its service life reaches more than 2.72 times that of ordinary NBR seals.
