4. FAQ
Q: What respective duties do different material parts perform in cylinder assembly?
A: PU bears core dynamic sealing, PTFE stops seal extrusion under sudden pressure, FKM seals endure high heat, textile ring guides reciprocating travel.

Q: Is any on-site trimming required during component installation?
A: All pieces follow OEM original dimensional standards and mount directly without cutting or sanding work.

Q: Is color or material reforming available for large bulk procurement?
A: Regular kits retain natural material hues; custom material proportion is only open to long-term big-volume orders.

Q: Which part suffers the maximum abrasion amid dusty construction conditions?
A: Impregnated textile guide ring contacts cylinder inner wall constantly and resists grit abrasion effectively.

Q: Does long-time continuous high-load operation trigger rubber bloating or severe fading?
A: Anti-aging modifiers are added into raw stock; slight color deepening never causes leakage or dimensional deformation.

Q: Can purchasers pick loose individual pieces instead of purchasing full whole kits?
A: Single-piece split supply is available, yet full set purchase cuts total cost for complete cylinder refurbishment.
