RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 30 mm ID, 42 mm OD, 5.7 mm Thickness 226-3774

RS PRO 226-3774 Nitrile Rubber (NBR) Rotary Shaft Seal offers precise sealing solutions for industrial and mechanical applications requiring a 30 mm inside diameter and 42 mm outside diameter.

This seal is constructed from high-quality nitrile rubber, known for its excellent resistance to lubrication oils, hydraulic fluids, and grease, making it ideal for use in driveshafts, crankshafts, and hydraulic cylinders where rotating shafts are lubricated to prevent leakage.

The seal thickness of 5.7 mm complements its robustness, ensuring long service life while maintaining flexibility. It operates efficiently within a temperature range of -20°C to 90°C, suitable for diverse industrial environments.

With a hardness of 70 ±5 Shore A, this seal balances firmness and elasticity. It features a tensile strength of 18.9 MPa and an elongation capacity of 438%, which contribute to its resilience under mechanical stress. The specific gravity of 1.25 ± 0.03 g/cm³ reflects the material’s density, while its tear resistance of 58 N/mm offers additional mechanical durability.

The black color of the seal simplifies visual inspection and ensures compatibility with various machinery components. This rotary shaft seal is essential in fluid power, mechanical engineering, and manufacturing processes requiring reliable sealing of rotating shafts.

Use cases include industrial machinery, automotive driveshafts, hydraulic equipment, agricultural machines, and general mechanical assemblies requiring a cost-effective and reliable seal solution.
