The CR Oil Seal 2.625x4.002x0.4375 CRWH1 NBR (Part No. 26356) is designed for industrial applications where sealing reliability, equipment protection, and long service life are essential.

The CRWH1 Profile utilizes SKF's advanced Wave Lip sealing technology. Unlike conventional sealing lips, the Wave Lip geometry creates a hydrodynamic pumping effect that helps return lubricant toward the oil side of the seal. This innovative design improves sealing efficiency while reducing friction, heat generation, and shaft wear during operation.

The seal features a double steel case construction that provides superior rigidity, secure housing retention, and dimensional stability under heavy-duty operating conditions. A carbon steel garter spring maintains consistent sealing pressure throughout the service life of the seal.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR remains one of the most widely used sealing materials due to its excellent balance of oil resistance, durability, flexibility, and cost-effectiveness.

With dimensions of 2.625 x 4.002 x 0.4375 inch, this seal is commonly used in industrial gearboxes, pumps, electric motors, agricultural machinery, speed reducers, conveyor drives, and imported industrial equipment utilizing inch-size shaft systems.
