The NATIONAL 2.375x3.616x0.290 200E NBR Oil Seal is engineered for rotary shaft applications requiring reliable sealing without the use of a garter spring. It is widely installed in automotive transmissions, differential assemblies, industrial gearboxes, pumps, electric motors, compressors, and OEM rotating equipment.

The 200E Profile features a precision metal case combined with a specially engineered springless elastomer sealing lip. Unlike conventional oil seals, this design does not utilize a garter spring. Instead, the sealing lip is precisely molded to generate the required radial sealing force through the elasticity of the NBR material itself.

This springless construction reduces friction between the sealing lip and shaft, resulting in smoother operation, reduced wear, simplified construction, and improved reliability in applications where spring-assisted sealing is unnecessary.

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

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

NBR provides excellent abrasion resistance, flexibility, and long-term durability for automotive and general industrial service. 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 2.375 × 3.616 × 0.290 inch, this oil seal is commonly used in automotive transmissions, industrial gearboxes, pumps, electric motors, compressors, agricultural machinery, and OEM rotating equipment utilizing inch-size shaft systems.
