RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 22 mm Inside Diameter, 40 mm Outside Diameter, 7 mm Thickness 226-3749

RS PRO 226-3749 Nitrile Rubber (NBR) Rotary Shaft Seal is engineered with precision for industrial sealing applications requiring oil and grease resistance. Featuring a 22 mm inside diameter, 40 mm outside diameter, and 7 mm thickness, this seal is optimal for use in driveshafts, crankshafts, and hydraulic cylinders where rotating shafts require lubrication containment.

The nitrile rubber compound is cost-effective and widely used due to its excellent resistance to lubrication oils, hydraulic fluids, and grease, although it is not suited for brake oil, phosphoric ester, or ester base fluids. The seal operates efficiently within a temperature range of -20°C to 90°C, making it suitable for diverse environmental conditions.

This rotary shaft seal offers a hardness of 70 ±5 Shore A, tensile strength of 18.9 MPa, and impressive elongation capability of 438%, ensuring mechanical durability and flexibility. Its tear resistance of 58 N/mm further supports longevity in heavy-duty industrial use. The black color and specific gravity of 1.25 ± 0.03 g/cm³ confirm consistent manufacturing standards.

This product is ideal for applications in mechanical, fluid power systems, construction machinery, manufacturing equipment, and automotive sectors where reliable sealing is critical. Its robust design helps prevent leakage, protect bearings, and maintain equipment efficiency.
