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 features do these sealing components possess?
A: The rubber sealing elements are matte black, and the outer steel shell shows bright silver finish after galvanized anti‑corrosion treatment.

Q: Which key assembly of the machine does this seal kit match?
A: It fits slewing drive shaft assembly, preventing hydraulic oil leakage at rotating shaft joint of container handler slewing unit.

Q: Can these sealing assemblies adapt frequent rotating and heavy container loading cycles?
A: Yes, it can bear repeated pressure impact and continuous mechanical shake during cargo stacking and position adjustment work.

Q: Does this kit supply all sealing spare parts for one slewing drive shaft overhaul?
A: Yes, it includes matched oil seals, high‑elastic garter springs and anti‑extrusion backup rings for single unit overhaul service.

Q: What temperature range can these sealing assemblies maintain stable sealing performance?
A: It keeps reliable sealing effect from ‑18℃ up to 160℃ under open‑air port working conditions.

Q: What temperature range can these sealing components keep stable sealing performance?
A: It maintains reliable sealing capacity from ‑26℃ up to 132℃ under outdoor high‑temperature road construction environment.

Q: What field working situations will speed up seal wear and aging?
A: Long‑time travelling on unpaved site roads, degraded gear lubricant and continuous mechanical vibration will shorten seal service life.

Q: Is this oil seal kit suitable for wheel hubs of multiple motor grader variants?
A: It is designed for dedicated shaft and bore dimensions, please verify dimension data before you confirm purchase orders.

Q: Can this oil seal kit fit torque converter assemblies of multiple wheel loader series?
A: It is manufactured for fixed shaft and bore dimensions, please confirm dimension specifications before placing purchase orders.

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.
