The CR 5.000x6.750x0.500 CRWH1 NBR Oil Seal (Part No. 50168) is engineered for industrial rotating equipment requiring advanced sealing performance and extended service life.

The CRWH1 Profile incorporates a double steel case construction, SKF WAVE lip design, and carbon steel garter spring. The WAVE lip technology creates a higher pumping rate while reducing friction and operating temperature at the sealing contact area, helping improve seal longevity and equipment reliability.

Unlike conventional straight-lip seals, the SKF WAVE lip geometry generates lower heat buildup and improved lubricant control. This reduces shaft wear and supports longer operating intervals between maintenance cycles.

The double steel case provides superior rigidity, dimensional stability, and secure retention in the housing bore, making the seal suitable for heavy-duty industrial machinery exposed to vibration, shock loads, and continuous-duty operation.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing lip offers excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants while maintaining flexibility and wear resistance.

With dimensions of 5.000 x 6.750 x 0.500 inch, this seal is commonly used in industrial gearboxes, pumps, conveyor drives, electric motors, mining equipment, and OEM rotating machinery utilizing inch-size shaft systems.
