The AEROQUIP 2.750x3.484x0.469 M/R NBR Oil Seal is engineered for heavy-duty rotating equipment requiring reliable sealing performance and extended service life. It is widely used in industrial gearboxes, hydraulic pumps, compressors, electric motors, agricultural machinery, construction equipment, mining equipment, and OEM rotating machinery.

The M/R Profile features a reinforced steel outer case together with a precision spring-loaded primary sealing lip. This proven industrial construction provides excellent housing retention, dimensional stability, and consistent sealing performance under continuous operation.

The integrated garter spring maintains constant radial pressure against the rotating shaft, minimizing lubricant leakage while protecting bearings, shafts, and internal rotating components from premature wear. The reinforced steel case provides excellent resistance to vibration, mechanical loads, and harsh industrial operating conditions.

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 long service life, making it ideal for industrial rotating equipment. 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 2.750 × 3.484 × 0.469 inch, this oil seal is commonly installed in industrial gearboxes, hydraulic pumps, compressors, electric motors, mining equipment, agricultural machinery, conveyor systems, construction machinery, and OEM equipment utilizing inch-size shaft systems.
