The AEROQUIP 1.813x2.540x0.703 NBR Oil Seal (Part No. C-938) is designed for rotating equipment that requires reliable oil sealing, protection against contamination, and long service life. It is suitable for OEM machinery as well as maintenance and overhaul applications across various industrial sectors.

This oil seal utilizes a spring-loaded sealing lip that continuously applies radial pressure to the shaft surface through an integrated garter spring. This ensures consistent sealing performance while minimizing lubricant leakage during continuous operation.

The reinforced metal case provides dimensional stability and secure retention within the housing, while the sealing lip effectively retains lubricants and prevents contaminants such as dust, dirt, moisture, and abrasive particles from entering the equipment. General-purpose rotary shaft oil seals of this type are commonly designed for low-pressure applications up to approximately 0.5 Bar, depending on operating conditions.

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

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

NBR provides excellent abrasion resistance, flexibility, and cost-effective sealing performance, making it the preferred material for most industrial rotary shaft sealing applications. Typical operating temperatures range from -40°C to +100°C, depending on lubricant compatibility and operating conditions.

With dimensions of 1.813 × 2.540 × 0.703 inch, this oil seal is commonly used in industrial pumps, speed reducers, gearboxes, compressors, agricultural machinery, conveyor drives, and OEM rotating equipment utilizing inch-size shaft systems.
