5. FAQ
Q: What construction machinery does part number 707‑98‑22890 apply for cylinder repair work?
A: Part number 707‑98‑22890 cylinder seal kit is specially developed for mini excavator boom swing cylinder assembly maintenance and full overhaul service.
Q: What sealing effect can part number 707‑98‑22890 bring to boom swing cylinder hydraulic circuit?
A: Part number 707‑98‑22890 cylinder seal kit maintains stable hydraulic pressure during boom swing left‑and‑right rotation, reduces internal bypass loss under offset digging load, and prevents site dust and fine gravel from entering cylinder interior to damage piston and rod sliding surfaces.
Q: What raw materials compose this boom swing cylinder seal kit?
A: Dynamic rod seals adopt high‑resilience PU polyurethane, static sealing O‑rings use oil‑resistant NBR nitrile rubber, and PTFE wear‑resistant wear band bears side thrust and prevents seal extrusion under frequent swing pressure fluctuation.
Q: What color features do these sealing spare parts have?
A: PU sealing elements are bright jet‑black, NBR rubber fittings are deep matte black, PTFE wear‑resistant wear band is light milky‑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.
