5. FAQ

Q: What road‑building construction machine does part number 707‑98‑25190 apply for cylinder repair service?
A: Part number 707‑98‑25190 cylinder seal kit is custom‑made for motor grader tilt cylinder assembly maintenance and full overhaul service.

Q: What sealing capability can part number 707‑98‑25190 deliver for grader tilt cylinder hydraulic circuit?
A: Part number 707‑98‑25190 cylinder seal kit maintains stable hydraulic pressure during moldboard tilt adjustment, reduces internal leakage under road‑surface trimming load, and blocks road dust and muddy splashes from entering cylinder chamber to protect piston and rod friction surfaces.

Q: What raw materials make up this tilt cylinder seal kit?
A: Dynamic rod seals adopt fatigue‑resistant PU polyurethane, static sealing O‑rings use aging‑resistant HNBR hydrogenated nitrile rubber, and PTFE anti‑fatigue backup rings buffer lateral twisting force and prevent seal squeeze damage under frequent angle‑switch pressure variation.

Q: What color characteristics do these sealing spare parts possess?
A: PU sealing pieces are deep dark‑black, HNBR rubber components are glossy jet‑black, PTFE shock‑resistant wear band is light cream‑white.

Q: Can this product prevent hydraulic oil leakage effectively?
A: The precise size design effectively reduces internal leakage and external oil seepage.

Q: What construction scenarios often require this arm cylinder seal kit for regular maintenance?
A: It is widely used for maintaining mini excavators working on villa foundation projects, landscape engineering, pipeline trenching and rural road reconstruction.
