The CR Oil Seal CR-19915 2.000x2.884x0.438 M/R NBR is a precision-engineered rotary shaft seal developed for industrial applications where reliable lubricant retention and equipment protection are essential.

The M/R (Metal Reinforced) construction combines a rigid steel outer case with a high-quality NBR sealing element, ensuring dimensional stability, secure housing retention, and excellent sealing performance. This design is particularly suitable for machinery exposed to vibration, continuous operation, and varying loads.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing lip offers excellent resistance to mineral oils, grease, hydraulic fluids, and common industrial lubricants. The material remains one of the most widely used sealing compounds due to its balance of durability, flexibility, and cost efficiency.

The 2.000 x 2.884 x 0.438 inch size is commonly used in industrial gearboxes, pumps, conveyors, compressors, agricultural machinery, and imported rotating equipment requiring dependable shaft sealing.
