RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 48 mm ID, 72 mm OD, 10 mm Thickness 226-3845

RS PRO 226-3845 Nitrile Rubber (NBR) Rotary Shaft Seal provides precise sealing solutions for industrial, mechanical, and hydraulic applications. Designed for shafts requiring oil or grease lubrication, this seal features a 48 mm inside diameter, 72 mm outside diameter, and 10 mm thickness to fit standardized assemblies.

The nitrile rubber material offers excellent resistance against oils, hydraulic fluids, and grease, making it widely used in driveshafts, crankshafts, and hydraulic cylinders. The operating temperature ranges from -20°C to 90°C, supporting use in diverse industrial and manufacturing environments.

With a shore hardness of 70 ±5 shore A, tensile strength of 18.9 MPa, and elongation of 438%, this seal delivers both toughness and flexibility. The specific gravity is approximately 1.25 g/cm³, and tear resistance stands at 58 N/mm, ensuring durability under mechanical stress.

This rotary shaft seal is not suitable for brake oil or ester-based fluids but excels in many other industrial sealing applications involving lubrication oils and hydraulic fluids.

Industries including automotive, manufacturing, construction, and fluid power systems rely on NBR seals like this RS PRO model for maintaining leak-free operation and equipment longevity.
