5. FAQ
Q: What heavy‑duty construction machine does part number 707‑98‑22070 serve for cylinder repair work?
A: Part number 707‑98‑22070 cylinder seal kit is specially produced for bulldozer steering cylinder assembly maintenance and full overhaul service.
Q: What sealing effect can part number 707‑98‑22070 realize for bulldozer steering cylinder hydraulic circuit?
A: Part number 707‑98‑22070 cylinder seal kit maintains steady hydraulic pressure during left‑right steering actions, reduces internal fluid bypass under rough terrain driving load, and blocks outside dust and muddy water from invading cylinder interior to protect internal moving matching surfaces.
Q: What raw materials constitute this steering cylinder seal kit?
A: Dynamic rod seals adopt high‑elastic PU polyurethane, static sealing O‑rings use oil‑resistant NBR nitrile rubber, and PTFE shock‑absorbing backup rings buffer transverse impact force and prevent seal extrusion under frequent pressure fluctuation.
Q: What color features do these sealing spare parts possess?
A: PU sealing elements are glossy deep black, NBR rubber accessories are matte jet‑black, PTFE shock‑absorbing backup rings are light milky‑white.
Q: What color appearance do these sealing spare parts present?
A: PU sealing elements are deep matte black, HNBR rubber fittings are glossy jet‑black, PTFE anti‑extrusion backup rings are light cream‑white.
Q: What sealing components are contained inside this complete repair kit?
A: It includes piston seals, rod seals, buffer rings, PTFE backup rings, dust wiper seals and multi‑spec matched O‑rings for cylinder reassembly.
Q: Can the sealing combination stop internal leakage and external oil seepage effectively?
A: Multi-stage sealing structure greatly reduces the risk of hydraulic oil leakage.
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.
