RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 25 mm Inside Diameter, 42 mm Outside Diameter, 7 mm Thickness 226-3760

RS PRO 226-3760 Nitrile Rubber (NBR) Rotary Shaft Seal is engineered to provide effective sealing solutions in mechanical systems involving rotating shafts. This seal is manufactured with high-quality nitrile rubber material, which offers excellent resistance to common industrial fluids such as lubrication oils, hydraulic fluids, and grease. Its design ensures reliable performance in driveshafts, crankshafts, and hydraulic cylinders where oil or grease lubrication is essential.

The seal measures 25 mm in inside diameter, making it suitable for shafts of this size, and features a 42 mm outside diameter to fit standard housings. With a thickness of 7 mm, this seal balances durability and effective sealing capability to prevent contamination and fluid leakage in rotating machinery.

Operating efficiently within a temperature range of -20°C to 90°C, this seal is appropriate for diverse industrial environments. It exhibits a Shore A hardness of 70 ±5, tensile strength of 18.9 MPa, and a tear resistance of 58 N/mm, contributing to its mechanical resilience. Furthermore, it possesses an elongation at break of 438%, allowing it to maintain integrity under dynamic mechanical stress.

The RS PRO nitrile seal is unsuitable for use with brake oil, phosphoric ester, and ester base fluids, ensuring users select the proper seal for their specific applications. The seal is black in color, the typical characteristic of nitrile rubber seals.

This rotary shaft seal is integral for maintaining fluid containment and preventing ingress of contaminants in various industrial, automotive, and hydraulic applications. It contributes to equipment longevity, operational efficiency, and safety in fluid power systems.

The seal features a 25 mm inside diameter ensuring compatibility with shafts of corresponding size. Its 42 mm outside diameter fits housings designed for this standard dimension. The 7 mm seal thickness optimizes sealing effectiveness and durability.
