5. FAQ

Q: What raw materials constitute the core dynamic sealing components of this seal kit?
A: The primary piston and rod seals adopt bamboo fiber modified HNBR elastomer. This set includes PU dust wiper rings, graphite silicon filled PTFE wear strips and POM back-up rings suitable for all standard sealing grooves of loader steering cylinders.

Q: How can buyers tell different sealing components apart by visual features?
A: HNBR main seals are glossy dark black with tight fine texture; PU wiper rings are brick brown; PTFE wear strips are off-white; POM back-up rings are silver grey. Every component is precision molded without uneven edges.

Q: What operation movements and working environments is this cylinder seal kit designed for wheel loader steering cylinders?
A: This set of seals adapts to frequent left and right steering reciprocating motion. It avoids hydraulic oil leakage and prevents silt infiltration during material loading, yard transportation and site material stacking operations.

Q: What temperature range ensures long-term steady operation of the whole sealing assembly?
A: Stable working temperature ranges from -98°C to 394°C. It fits low-temperature outdoor bulk cargo handling and all-day operation under high-temperature open stockyards.

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

Q: What continuous hydraulic pressure can this matched sealing assembly withstand during repeated cyclic operation?
A: Cooperated with wear strips and back-up rings, the sealing system can continuously bear pressure between 5.30MPa and 6.10MPa and buffer pressure fluctuations during frequent steering adjustments.

Q: What working scenarios usually require this steering cylinder seal kit for regular maintenance?
A: It is widely used for servicing loaders working at quarry transfer yards, port cargo areas, concrete mixing plants and construction waste treatment sites.

Q: What core strengths does bamboo fiber modified HNBR have compared with conventional nitrile rubber seals?
A: Bamboo fiber improves low-temperature flexibility and anti-extrusion property. Under periodic steering alternating loads, its service life exceeds 2.40 times ordinary NBR sealing spare parts.
