Radial Shaft Sealing Ring BS4/6
Engineered with a precision sealing lip and reinforced metal outer structure, the seal maintains consistent sealing pressure even under high rotational speeds, heavy axle loads, and extreme temperature variations. Its elastomer compound resists wear, oil breakdown, and deformation, ensuring long-term sealing efficiency. The seal is specially designed to support the advanced emission and thermal requirements of BS4/BS6 axle systems.
By protecting the hub from dust, moisture, and debris, the sealing ring enhances bearing life, reduces maintenance costs, and ensures smoother, more reliable axle operation. It plays a crucial role in maintaining drivetrain health and overall vehicle performance.
Key Features
- High-performance radial seal for BS4 & BS6 axle systems
- Prevents oil leakage and contaminant ingress
- Reinforced metal case for secure mounting and durability
- Heat, wear, and chemical-resistant elastomer construction
- Ensures long-lasting sealing and protects rear axle bearings
