4. FAQ

Q: What raw material is used for the main sealing components inside this wheel loader cylinder seal kit?
A: Core piston and rod seals adopt poplar fiber reinforced HNBR elastomer. This set also contains PU dust wiper rings, graphite molybdenum filled PTFE wear strips and POM back-up rings to fit all sealing grooves of bucket cylinders.

Q: How can buyers tell different sealing accessories apart through appearance features?
A: HNBR primary seals are smooth matte black with fine uniform texture; PU wiper rings are amber brown; PTFE wear strips are creamy white; POM back-up rings are light silver grey. All components are precision molded without rough edges.

Q: What working scenarios is this cylinder seal kit developed to adapt to wheel loader bucket cylinders?
A: This set of seals fits repeated digging and unloading movements of loader buckets. It prevents hydraulic oil leakage and blocks building site sediment when shoveling sand, stones and bulk raw materials.

Q: What temperature range supports stable long-term operation of the whole sealing assembly?
A: Reliable working temperature ranges from -118°C to 414°C. It can handle low-temperature material handling in northern zones and continuous work under high-temperature quarry and mixing plant environments.

Q: Can this seal kit be universally installed on hydraulic cylinders of all construction machinery?
A: It is dimensionally customized exclusively for wheel loader bucket cylinders. It cannot match motor grader swing cylinders, excavator arm cylinders or road roller drive cylinders of other machine specifications.

Q: What lasting hydraulic pressure can this matched sealing assembly withstand during repeated cyclic work?
A: With the cooperation of wear strips and back-up rings, the sealing system can steadily bear pressure ranging from 5.80MPa to 6.60MPa and relieve pressure impact when the bucket cuts into hard materials.

Q: What engineering fields usually need this bucket cylinder seal kit for periodic maintenance?
A: It serves regular maintenance for wheel loaders working at aggregate quarries, concrete batching plants, logistics yards, and large infrastructure construction sites.

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.
