5. FAQ
Q: What road construction machine does part number 707‑98‑25830 fit for cylinder maintenance work?
A: Part number 707‑98‑25830 cylinder seal kit is specially developed for motor grader articulation cylinder assembly maintenance and full overhaul service.
Q: What sealing result can part number 707‑98‑25830 achieve for articulation cylinder hydraulic circuit?
A: Part number 707‑98‑25830 cylinder seal kit holds steady hydraulic pressure while the grader front frame swings left and right, cuts down internal oil leakage under frame‑swing torsion load, and keeps road sand and muddy debris out of cylinder chamber to protect piston and rod sliding surfaces.
Q: What raw materials make up this articulation cylinder seal kit?
A: Dynamic rod seals adopt high‑tear‑strength PU polyurethane, static sealing O‑rings use ozone‑resistant HNBR hydrogenated nitrile rubber, and PTFE load‑bearing backup ring absorbs cross‑direction torsion force and prevents seal extrusion damage under frequent frame swing pressure changes.
Q: What raw materials make up this steering cylinder seal kit?
A: Dynamic rod seals adopt high‑flex PU polyurethane, static sealing O‑rings use oil‑resistant NBR nitrile rubber, and PTFE distortion‑resistant wear band withstands lateral deflection force and avoids seal squeeze damage under frequent steering pressure conversion.
Q: What color appearance do these sealing spare parts feature?
A: PU sealing elements are deep dark‑black, HNBR rubber fittings are glossy jet‑black, PTFE pressure‑resistant backup rings are light ivory‑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.
