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 is the visual appearance of these sealing components?
A: The rubber lip is deep black with fine matte texture, and the metal shell has uniform reddish‑brown anti‑rust coating on outer surface.

Q: How is its compatibility with common mechanical lubricants?
A: NBR material delivers reliable oil resistance, keeps low‑swelling performance for gear oil and heavy‑duty bearing grease used for lifting equipment.

Q: What suggestions for warehouse storage of unopened seal kits?
A: Store in cool dry indoor zone. Avoid heavy stacking pressure, sharp scratches and long‑time exposure to ultraviolet rays.

Q: Can fitters reuse seal assemblies removed from shaft position?
A: Re‑installation is not recommended. Seals lose built‑in radial pre‑tension after disassembly and may trigger slow oil leakage under frequent lifting vibration.

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.
