5. FAQ

Q: What reinforcing filler is added into the polyurethane base material of the primary piston sealing ring?
A: Short-cut glass fiber powder is evenly mixed into PU raw material. It effectively slows down irreversible surface abrasion caused by long-term back-and-forth piston movement inside tilt cylinders and avoids volume expansion after long-time immersion in high-pressure hydraulic transmission oil.

Q: What clear color and surface texture differences can buyers distinguish among all three types of sealing components inside this repair kit?
A: The main PU piston seals are matte dark black with dense compact grain on the surface. Mica filled PTFE retaining rings are light beige with slightly matte smooth texture, while EPDM elastic backing rings are dark grey, convenient for sorting during cylinder disassembly and maintenance.

Q: What three-layer composite integrated matching structure does this piston seal set adopt for medium heavy wheel loader tilt cylinders?
A: It is an all-in-one matched component group instead of single independent piston rings, consisting of main PU piston seal, anti-extrusion PTFE retaining rings and elastic pre-tightening backing rings, fully matching all piston sealing grooves of tilt hydraulic cylinders.

Q: What full stable operating temperature range can this whole piston sealing assembly maintain reliable sealing capacity?
A: Its applicable temperature range spans -162°C to 392°C, suitable for freezing plateau winter aggregate loading and continuous heavy bucket tilt operation under high-temperature open-air construction yards.

Q: Can this piston seal assembly be universally installed on hydraulic cylinders of all construction machinery types?
A: It is specially sized and formula customized only for medium heavy wheel loader tilt cylinder piston structures, and cannot fit road grader steering cylinders, mini excavator arm cylinders or bulldozer lift cylinders of other equipment series.

Q: What peak instantaneous hydraulic pressure can the composite piston seal combination withstand without extrusion damage?
A: The three-layer matched sealing structure can resist instantaneous hydraulic pressure up to 6.8MPa, buffer sharp pressure surges generated by frequent bucket tilt and reset, and eliminate internal hydraulic oil leakage inside the cylinder cavity.

Q: What core construction and stockyard scenarios require this piston seal kit for regular hydraulic cylinder overhaul maintenance?
A: It is designed for daily maintenance of tilt cylinder piston assemblies on medium heavy wheel loaders, widely applied in quarry aggregate stacking, municipal foundation backfilling, bulk grain yard handling and highway roadbed construction projects.
