CR 70x85x8 Metric Rotary Shaft Lip Seal | High-Performance NBR Industrial Oil Seal

The 70 X 85 X 8 metric rotary shaft seal (oil seal) is precision-engineered to provide robust protection against fluid leakage and external contaminants in industrial environments. Utilizing a resilient Nitrile Butadiene Rubber (NBR) sealing lip and a robust steel case insert, this seal is designed for demanding standard rotating applications where mineral oils, greases, or water-based emulsions are present. The precise 70mm inner diameter ensures a secure, pressure-fit sealing surface on the shaft, while the 85mm outer diameter provides stable housing retention, preventing rotational creep and ensuring maximal uptime. As a high-quality component within the CR product lineage, this 70x85x8 seal delivers reliable performance across a broad temperature range (-40°C to +100°C) and is characterized by excellent resistance to abrasion and common industrial media. Ideal for pumps, gearboxes, motors, and transmission systems, this component minimizes friction, lowers power consumption, and significantly extends the service life of internal machine components by maintaining optimal lubrication levels. This seal is a critical investment for preventative maintenance programs requiring dependable sealing integrity.

Key Features

• Precision NBR compound offers excellent compatibility with standard industrial lubricants and greases.
• Spring-loaded sealing lip ensures consistent radial load against the shaft, even under minor runout conditions.
• Integrated metal case provides structural rigidity and secure press-fit retention in the housing bore.
• Effective fluid retention and superior exclusion of dust, dirt, and splash water.
• Standard metric dimensions simplify replacement and ensure high compatibility with global industrial machinery standards.
