The CR 1.688x2.690x0.500 CRW1 NBR Oil Seal (Part No. 16842) is engineered for industrial rotating equipment requiring reliable lubricant retention and protection against external contaminants. As one of the most recognized sealing solutions from CR (Chicago Rawhide), the CRW1 profile has become an industry standard for industrial machinery, gearboxes, pumps, and rotating equipment worldwide.

The CRW1 Profile features a reinforced metal outer case combined with a spring-loaded primary sealing lip and an auxiliary dust lip. The primary sealing lip is energized by a garter spring that maintains consistent radial pressure against the shaft surface, ensuring reliable sealing performance throughout the operating life of the seal.

The auxiliary dust lip provides additional protection by preventing dust, dirt, moisture, and abrasive particles from entering the equipment. This dual-lip construction significantly improves bearing protection and extends equipment life in contaminated operating environments.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this seal provides excellent resistance to mineral oils, gear oils, lubricating greases, hydraulic fluids, and petroleum-based lubricants. NBR is widely used in industrial sealing applications because of its excellent oil resistance, flexibility, abrasion resistance, and cost-effective performance.

The metal case construction ensures secure housing retention and dimensional stability, while the dual-lip sealing arrangement reduces lubricant leakage and protects internal components from contamination. This makes the CRW1 design particularly suitable for industrial gearboxes, pumps, electric motors, agricultural machinery, compressors, and continuous-duty rotating equipment.

With dimensions of 1.688 x 2.690 x 0.500 inch, this seal is commonly used in industrial maintenance, OEM machinery, power transmission equipment, conveyor systems, and heavy-duty industrial applications requiring inch-size shaft seals.
