Radial Shaft Sealing Ring BS3
Its engineered sealing lip ensures consistent pressure against the rotating shaft, maintaining long-lasting sealing effectiveness even under continuous vibration, heat, and heavy load conditions. Made from a robust elastomer compound with a reinforced metal outer shell, it delivers excellent resistance to oil, dust, water, and temperature fluctuations. This ensures stable hub performance and extended bearing life in demanding commercial operations.
By maintaining a clean and well-lubricated hub environment, the sealing ring supports smooth wheel rotation, reduces wear, and enhances overall vehicle reliability.
Key Features
- High-quality radial shaft seal for BS3 rear axle systems
- Prevents oil leakage and blocks dust, mud, and moisture
- Elastomer lip with reinforced metal casing for durability
- Resistant to heat, wear, and chemical exposure
- Enhances bearing life and axle performance

FAQ
What does the BS3 sealing ring do?
It keeps lubricant inside the hub while preventing external contaminants from damaging bearings.
When should it be replaced?
Replace when oil leaks appear, contamination is present, or during a hub overhaul.
