4. FAQ
Q: Can this oil seal work steadily on rotating shaft assemblies?
A: Yes, the specially designed sealing lip fits rotary shafts to block internal lubricant leakage.
Q: What color options do these sealing accessories have?
A: The main shaft seal is black rubber with dark grey metal shell, POM backup rings are off‑white, and matched O‑rings are deep black.
Q: What hydraulic oil specification fits these sealing elements well?
A: It adapts to general anti‑wear hydraulic oil commonly used for multi‑function material handler hydraulic circuits.
Q: Are external dust‑proof wiper seals included in this whole repair set?
A: Wiper seals are supplied, blocking scrap debris, fine dust and moisture from invading rotary joint clearance gaps.
Q: What field working factors will shorten the service life of these seal assemblies?
A: Intermittent frequent swing operation, contaminated hydraulic medium and uneven pressure fluctuation will accelerate seal wear.
Q: Is this oil seal kit compatible with rotary joints of other similar material handler versions?
A: It matches dedicated shaft and bore dimensions, please confirm dimension data before submitting your purchase order.
Q: What abnormal conditions indicate oil seals should be replaced?
A: Lubricant leaks out from conveyor drive shaft end, conveyor runs unevenly, periodic scraping noise occurs and drive housing produces obvious over‑heat during paving work.
Q: What risk will scratch damage bring to electrophoretic coated shell?
A: Once the coating layer is scratched off, bare steel will corrode gradually, which may lead to seal loosening and unexpected oil leakage.
Q: How well can this full sealing kit block mud, gravel dust and hot gear oil mist on muddy outdoor road job sites?
A: The multi-layer flexible rubber lip scrapes thick mud off the shaft surface, the fully enclosed plated metal shell blocks coarse dust particles, and inner auxiliary rubber layers isolate high-temperature oil mist to protect internal precision gears.
