The AEROQUIP 48x62x8 SB NBR Oil Seal (Part No. C-289) is engineered for rotary shaft applications requiring dependable sealing performance and protection of critical machine components.

The SB Profile utilizes a metal outer case combined with a spring-loaded single sealing lip. This design provides secure housing retention, dimensional stability, and effective sealing performance while minimizing friction during operation. SB oil seals are commonly used in electric motors, gearboxes, pumps, speed reducers, and rotating industrial equipment.

The sealing lip is designed to maintain consistent contact with the shaft surface, preventing lubricant leakage while protecting internal components from dust, moisture, and environmental contamination. This helps improve equipment reliability and reduce maintenance requirements.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal provides excellent resistance to lubricating oils, hydraulic fluids, grease, and petroleum-based lubricants. NBR is one of the most widely used sealing materials because of its excellent oil resistance, flexibility, wear resistance, and cost-effective performance. Typical NBR oil seals can operate within approximately -40°C to +100°C depending on application conditions.

With dimensions of 48 x 62 x 8 mm, this oil seal is commonly used in electric motors, industrial pumps, gearboxes, agricultural machinery, conveyor systems, and imported industrial equipment requiring metric-size shaft seals. Similar 48x62x8 NBR oil seals are widely used in motors, gearboxes, transmissions, and industrial machinery.
