The REPCO 2.500x3.437x0.563 M/R NBR Oil Seal is engineered for rotating equipment operating under continuous industrial service where dependable sealing performance is critical. It is widely used in industrial pumps, gearboxes, electric motors, compressors, conveyor systems, agricultural machinery, mining equipment, construction equipment, and OEM rotating machinery.

The M/R Profile features a reinforced steel outer case combined with a spring-loaded primary sealing lip, providing excellent dimensional stability, secure housing retention, and consistent sealing force throughout the service life of the seal.

An integrated garter spring continuously maintains radial sealing pressure against the rotating shaft, effectively minimizing lubricant leakage while protecting bearings, shafts, and internal rotating components from dust, moisture, and premature wear.

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

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

NBR provides outstanding abrasion resistance, elasticity, and long-term 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 2.500 × 3.437 × 0.563 inch, this oil seal is commonly installed in industrial gearboxes, pumps, electric motors, compressors, mining equipment, agricultural machinery, conveyor systems, and OEM equipment utilizing inch-size shaft systems.
