5. FAQ

Q: What heavy‑duty construction machinery does part number 707‑98‑29500 suit for cylinder repair and maintenance?
A: Part number 707‑98‑29500 cylinder seal kit is precisely produced for excavator swing boom cylinder assembly maintenance and full overhaul service.

Q: What sealing effect can part number 707‑98‑29500 bring to swing boom cylinder hydraulic circuit?
A: Part number 707‑98‑29500 cylinder seal kit maintains stable hydraulic pressure during swing boom offset and reset movements, reduces internal oil flow loss under offset digging load, and blocks fine construction dust and damp earth residue from invading cylinder chamber to protect piston and rod friction surfaces.

Q: What raw materials compose this swing boom cylinder seal kit?
A: Dynamic rod seals adopt high‑elastic PU polyurethane, static sealing O‑rings use oil‑resistant NBR nitrile rubber, and PTFE stress‑relief backup ring releases uneven torsional stress and prevents seal extrusion damage under frequent offset pressure changes.

Q: What color features do these sealing spare parts present?
A: PU sealing components are glossy jet‑black, FKM rubber fittings are dark brown‑black, PTFE pressure‑dispersion wear ring is light off‑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.
