RS PRO Nitrile Rubber Rotary Shaft Seal, 35 mm ID, 72 mm OD, 10 mm Thickness 226-3804

RS PRO 226-3804 Rotary Shaft Seal delivers dependable sealing for rotating shafts, crankshafts, and hydraulic cylinders in industrial settings. Engineered from nitrile rubber (NBR), one of the most cost-effective and commonly-used sealing materials, it offers a strong combination of mechanical strength and oil resistance.

This seal is designed with a 35 mm inside diameter, a 72 mm outside diameter, and a 10 mm thickness, ensuring compatibility with a wide range of standard shaft assemblies. Its rotary shaft seal configuration makes it ideal for applications where a lubricated shaft requires protection from dust, oil, and other contaminants.

The NBR composition provides excellent resistance to lubrication oils, hydraulic fluids, and grease, making it suitable for oil-lubricated environments. The seal is not intended for use with brake oil, phosphoric ester, or ester-base fluids, ensuring safety and material integrity.

With an operating temperature range between -20°C and 90°C, the RS PRO 226-3804 can be used in both low and moderately high temperature applications. Mechanical characteristics such as a hardness of 70 ±5 Shore A, tensile strength of 18.9 MPa, elongation of 438%, specific gravity of 1.25 ±0.03 g/cm³, and tear resistance of 58 N/mm reinforce reliability and structural stability under mechanical loads.

Constructed from high-quality nitrile rubber (NBR) for durability and chemical resistance. 35 mm inside diameter and 72 mm outside diameter for standard shaft compatibility. 10 mm thickness enhances sealing performance. Rotary shaft seal design suitable for driveshafts, crankshafts, and hydraulic cylinders.

Temperature range from -20°C to 90°C ensures reliable operation in a variety of environments. Hardness rated at 70 ±5 Shore A, providing consistent elasticity and resilience. Excellent resistance to lubrication oils, hydraulic fluids, and grease for extended service life.

Tear resistance of 58 N/mm and tensile strength of 18.9 MPa contribute to mechanical strength. Black color and robust construction for easy identification and installation.

This RS PRO seal is particularly useful in mechanical power transmission, industrial machinery, fluid power systems, and manufacturing environments. It is also commonly employed in maintenance, repair, and operations for sealing shafts and preventing fluid leakage.
