RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 20 mm ID, 40 mm OD, 7 mm Thickness 226-3744

RS PRO 226-3744 Nitrile Rubber (NBR) Rotary Shaft Seal with 20 mm inside diameter, 40 mm outside diameter, and 7 mm thickness provides reliable sealing solutions in industrial mechanical applications. The robust nitrile material offers excellent resistance to lubrication oils, hydraulic fluids, and grease, making it ideal for use in driveshafts, crankshafts, and hydraulic cylinders requiring efficient oil or grease lubrication.

This seal maintains operational integrity across a temperature range of -20°C to 90°C, supported by a hardness rating of 70 ±5 Shore A that balances durability and flexibility. The tensile strength of 18.9 MPa combined with elongation at 438% ensures the seal can withstand mechanical stress and deformation without failure.

The material's specific gravity of 1.25 ± 0.03 g/cm³ ensures consistent density, and the tear resistance value of 58 N/mm improves seal lifetime even in demanding industrial environments. The RS PRO Nitrile Rubber Seal is widely employed in industries such as manufacturing, automotive maintenance, hydraulic systems, and fluid power applications where reliable shaft sealing is critical.

Durable nitrile rubber construction for oil and grease resistance. Dimensions optimized for rotary shaft sealing tasks. Range of mechanical properties support longevity in industrial use. Temperature tolerant between -20°C and 90°C for diverse environments.
