The AEROQUIP 2.313x3.355x0.313 M/R NBR Oil Seal is engineered for rotating equipment requiring reliable sealing performance and long service life. It is widely used in industrial gearboxes, pumps, electric motors, compressors, speed reducers, agricultural machinery, and OEM rotating equipment where dependable lubricant retention is essential.

The M/R Profile consists of a reinforced metal outer case combined with a spring-loaded primary sealing lip. This proven industrial design provides excellent housing retention, dimensional stability, and consistent sealing performance throughout extended operating periods.

The integrated garter spring continuously maintains sealing pressure against the rotating shaft, minimizing lubricant leakage while protecting bearings, shafts, and other rotating components from premature wear. The precision-engineered sealing lip provides excellent contact with the shaft surface while reducing friction and extending service life.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this oil seal provides excellent resistance to:

• Mineral oils
• Hydraulic oils
• Gear oils
• Lubricating grease
• Petroleum-based lubricants

NBR offers excellent abrasion resistance, flexibility, and durability for general industrial applications. Typical operating capability is up to 0.5 Bar, with operating temperatures ranging from -40°C to +100°C, depending on shaft speed, lubrication, and operating conditions.

With dimensions of 2.313 × 3.355 × 0.313 inch, this oil seal is commonly installed in industrial gearboxes, pumps, electric motors, compressors, agricultural machinery, conveyor systems, power transmission equipment, and OEM machinery utilizing inch-size shaft systems.
