Features & Benefits
Dual lip construction delivers primary oil retention and secondary dust & mud exclusion for harsh rotary shaft working environments.
Integrated garter spring maintains stable radial contact pressure on the sealing lip during continuous shaft rotation.
Brown NBR nitrile rubber offers excellent wear resistance and good compatibility with mineral engine oil and gear lubricants.
The special stepped height profile 8/9.8mm matches vehicle housings requiring two-stage stepped installation geometry.
Metal outer casing provides rigid support for secure press-fit installation inside housing bore.
This seal is an aftermarket replacement part; verify shaft, bore dimensions and working condition before placing your order.
Material & Specification
- Sealing lip：NBR nitrile butadiene rubber, brown
