description

Rubber seal ring is main sealing component for final drive and wheel hub. It relies on rubber elasticity to fit mating surface, retain gear oil inside and block mud and sewage to protect precision gears and bearings. Aging, cracking, bulging and permanent deformation of rubber will lead to oil leakage. Muddy water ingress will cause rapid rust and wear of gears and bearings.

FAQ 

Q：Can I keep using the seal if it leaks slightly?
A：Long-term use is not recommended. Once rubber ages, leakage will worsen, and muddy water will damage internal drive parts.

Q：What happens if the seal lip is installed backwards?
A：It cannot retain gear oil and will leak rapidly, the seal fails immediately.

Q：Will a new seal work if the shaft has fine scratches?
A：Scratches will cut the seal lip repeatedly and cause re-leakage. Repair or replace the shaft first.

Q：Can I replace it with another rubber seal model?
A：Not recommended. Different dimension, lip design and oil resistance formula lead to short service life.
