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 can we observe for these sealing spare parts?
A: Rubber components are matte black, and metal shells show silver‑grey finish after anti‑rust treatment.

Q: Which core mechanical position is this seal kit designed for installation?
A: It is mainly assembled on gearbox rotating shaft assemblies of combine harvester agricultural machinery.

Q: Does this complete overhaul kit contain matched backup rings and small auxiliary gaskets?
A: Yes, supporting backup rings and assorted gaskets are included for full gearbox maintenance operation.

Q: How will this sealing set perform while contacting gear oil and agricultural machinery lubricating grease?
A: Nitrile rubber keeps stable dimension performance and shows low swelling for common mineral‑based lubricants.

A: Keep in cool dry storage zone, avoid sharp impact, heavy pressure and continuous light exposure.

Q: Can maintenance workers reuse these seal components once removed from the shaft assembly?
