Product Description

RS PRO 226-3880 nitrile rubber (NBR) rotary shaft seal is engineered for industrial applications requiring effective sealing solutions. With a 65 mm inside diameter, 80 mm outside diameter, and 8 mm thickness, this seal is suitable for driveshafts, crankshafts, and hydraulic cylinders lubricated by oil or grease.

The nitrile rubber material offers excellent resistance to lubrication oils, hydraulic fluids, and grease, making it ideal for automotive, manufacturing, and fluid power industries. However, this seal is not recommended for use with brake oil or phosphoric ester fluids.

This seal operates reliably within the temperature range of -20°C to 90°C, accommodating a wide spectrum of industrial environments. It has a hardness rating of 70 ±5 shore A, providing the strength needed to resist wear and deformation.

Key mechanical properties include a tensile strength of 18.9 MPa and tear resistance of 58 N/mm, ensuring durability under mechanical stress. The material’s elongation of 438% supports flexibility and a tight seal during shaft rotation.

The black-colored nitrile construction ensures easy compatibility and visibility in mechanical assemblies. Its specific gravity of approximately 1.25 g/cm³ confirms material consistency for optimal performance.

Made from nitrile rubber (NBR) for oil and hydraulic fluid resistance. Suitable for rotary shaft sealing applications in heavy-duty machinery. Operates effectively within -20°C to 90°C temperature range. Hardness of 70 ±5 shore A for robust wear resistance.

Tensile strength and tear resistance for long service life. High elongation for flexibility and effective sealing. Black coloration for industrial use and easy identification.

This RS PRO seal is essential for maintenance and repair in fluid power systems, automotive components, and machine assemblies. It supports efficient lubrication retention and contamination exclusion.
