5. FAQ

Q: What is the fuction of the bushing ?
A: The bushing acts as a guide for the piston rod. It bears the radial / side load when the cylinder works, preventing direct metal‑to‑metal contact between the piston rod and the cylinder head. It reduces friction and wear. If the bushing is worn out, the piston rod will wobble, which will quickly damage the oil seals and cause oil leakage.

Q: How will this sealing kit perform when exposed to heavy‑duty gear oil and chassis general‑purpose grease?
A: Polyacrylate rubber delivers good heat‑oil resistance and keeps low‑swelling property for various mineral‑based lubricants.

Q: What storage suggestions should we follow for spare seal kits in warehouse?
A: Keep in cool dry indoor storage area, avoid heavy stacking deformation, surface scratch and long‑time ultraviolet irradiation.

Q: Can field service technicians reuse these seal components after dismounting from shaft assembly?
A: Re‑installation is not recommended. Lip radial pre‑compression force will drop after removal and bring hidden oil‑leakage risk.

Q: What practical working symptom reminds maintenance staff to replace seals timely?
A: Slow lubricant seepage mixed with stone dust particles around drive‑shaft housing indicates seal abrasion and thermal aging.

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.
