The SCHNEIDER 2.375x3.254x0.313 M/R NBR Oil Seal is engineered for industrial rotating equipment requiring reliable lubricant retention, contamination protection, and long service life. This seal is suitable for a wide range of industrial and OEM applications where continuous operation and dependable sealing performance are essential.

The M/R Profile is a traditional industrial rotary shaft seal design featuring a reinforced metal outer case and a spring-loaded sealing lip. The metal case provides dimensional stability and secure housing retention, while the garter spring maintains consistent radial pressure against the shaft surface to ensure effective sealing throughout the service life of the seal.

The sealing lip is specifically designed to retain lubricating oil and grease within the equipment while preventing dust, dirt, moisture, and abrasive contaminants from entering the system. This protection helps extend the life of bearings, shafts, gears, and other rotating components while reducing maintenance costs and equipment downtime.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this seal offers excellent resistance to mineral oils, hydraulic fluids, gear oils, lubricating greases, and petroleum-based lubricants. NBR is widely recognized for its excellent oil resistance, wear resistance, flexibility, and cost-effective performance in industrial environments.

The spring-loaded lip design compensates for minor shaft wear and eccentricity, helping maintain sealing efficiency during extended operating periods. This makes the seal particularly suitable for industrial pumps, gearboxes, reducers, compressors, agricultural machinery, and heavy-duty rotating equipment.

With dimensions of 2.375 x 3.254 x 0.313 inch, this oil seal is commonly used in industrial pumps, gearboxes, electric motors, conveyor systems, agricultural machinery, and OEM equipment utilizing inch-size shaft systems.
