4. FAQ

Q: Can this piston seal ring adapt to hydraulic cylinders of all construction equipment?
A: It is specially matched for grader lift cylinders. It cannot be installed on excavator stick cylinders or wheel loader tilt cylinders.

Q: What’s the main function of this piston seal ring?
A: It supports the piston and avoids direct metal contact to reduce wear of hydraulic cylinder parts.

Q: What working pressure can this wear ring withstand?
A: It fits medium and high pressure hydraulic systems used on construction machinery.

Q: Can it work continuously under frequent reciprocating movement?
A: Sure, the nylon material offers outstanding abrasion resistance for long-term reciprocating operation.

Q: Is this product supplied as single piece or complete sets?
A: We support both single-piece supply and matched bulk packing according to customer demands.

Q: What hydraulic media can this ring adapt to?
A: It is compatible with regular mineral hydraulic oil used on most excavator equipment.

Q: What core function does this piston seal ring perform inside the cylinder?
A: It separates high-pressure and low-pressure oil chambers inside the cylinder and prevents hydraulic fluid from flowing across both sides of the piston.

Q: What engineering projects commonly require replacement of this piston seal ring?
A: It serves routine maintenance of hydraulic cylinder piston sealing assemblies on medium crawler excavators, widely used in urban infrastructure, highway subgrade construction, small quarry loading and residential foundation excavation projects.
