4. FAQ

Q: What materials compose this oil seal kit?
A: The sealing lip is XNBR carboxylated nitrile rubber for superior wear resistance, and outer shell is galvanized stamped‑steel equipped with high‑strength helical garter spring.

Q: What lip layout is adopted for this reach‑stacker seal kit?
A: It features triple‑lip integrated construction. Outer dust lip blocks port dust, container debris and salt‑containing water splashes under frequent heavy‑weight container stacking operations.

Q: What temperature range can this seal sustain for stable running?
A: It delivers reliable sealing performance from ‑33℃ up to 112℃ under high‑load, humid and salt‑fog port operating environment.

Q: Where is this oil seal kit installed on machinery?
A: It is fitted on drive‑axle rotating shaft assemblies of reach stacker port handling equipment.

Q: Does this repair kit include all supporting sealing spare parts for one‑set overhaul?
A: Yes, matched backup rings and assorted small auxiliary gaskets are included for complete drive‑axle system maintenance work.

Q: How will this sealing kit perform when exposed to different lubricants on site?
A: HNBR rubber owns outstanding heat‑aging resistance and maintains low‑swelling rate for axle gear oil and drive‑axle bearing grease.

Q: Can port maintenance technicians reuse these seal assemblies after disassembly?
A: Re‑installation is not recommended. Lip pre‑tightening stress will weaken after removal and may trigger slow lubricant leakage under humid port conditions.

Q: What practical working sign tells technicians to replace seals promptly?
A: Gradual grease seepage mixed with street sand and dust particles around brush‑drive housing indicates seal abrasion and gradual aging performance drop.
