5. FAQ

Q: What heavy‑duty construction machine does part number 707‑98‑22020 apply for cylinder maintenance?
A: Part number 707‑98‑22020 cylinder seal kit is designed for bulldozer lift cylinder assembly maintenance and full overhaul service.

Q: What sealing performance can part number 707‑98‑22020 deliver for bulldozer lift cylinder hydraulic circuit?
A: Part number 707‑98‑22020 cylinder seal kit maintains consistent hydraulic pressure during dozer blade lifting and lowering movements, minimizes internal pressure drop under heavy earth‑pushing load, and prevents abrasive soil and rock dust from entering cylinder chamber to abrade piston and rod mating surfaces.

Q: What raw materials are used for this lift cylinder seal kit?
A: Dynamic rod seals adopt wear‑resistant PU polyurethane, static O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE heavy‑load backup rings bear large lateral force and prevent seal squeeze damage under peak working pressure.

Q: What color can customers expect for these sealing components?
A: PU sealing parts are deep jet‑black, FKM rubber fittings are dark brown‑black, PTFE heavy‑load backup rings are light cream‑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.
