RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 18 mm ID 32 mm OD 7 mm Thickness 226-3730

RS PRO 226-3730 is a high-quality Nitrile Rubber (NBR) Rotary Shaft Seal designed with an 18 mm inside diameter and a 32 mm outside diameter, featuring a 7 mm thickness. This seal is specialized for use in rotating shafts requiring effective oil and grease retention, commonly applied in driveshafts, crankshafts, and hydraulic cylinders.

The seal material, Nitrile Rubber (NBR), provides excellent resistance to lubrication oils, hydraulic fluids, and grease, making it a cost-effective choice for industrial sealing applications. It is not suitable for brake oils, phosphoric ester, or ester-based fluids.

Designed for operating temperatures ranging from -20°C to 90°C, the RS PRO seal ensures reliable performance under variable thermal conditions. The material hardness is rated at 70 ±5 shore A, balancing flexibility and wear resistance to extend service life.

Key mechanical properties include a tensile strength of 18.9 MPa, elongation capability of 438%, a specific gravity of 1.25 ± 0.03 g/cm³, and tear resistance of 58 N/mm. These properties make the seal resistant to mechanical stresses and ensure sustained sealing integrity.

The RS PRO 226-3730 Nitrile Rubber Seal is ideal for industrial use in mechanical machinery and fluid power systems, including automotive and hydraulic equipment. Its design supports maintenance and repair tasks requiring dependable seal solutions.

Made from durable Nitrile Rubber (NBR) material resistant to oils, hydraulic fluids, and grease. Measures 18 mm inside diameter (ID) and 32 mm outside diameter (OD) for precise fit. Seal thickness is 7 mm, ensuring effective sealing performance.
