RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 20 mm ID, 30 mm OD, 7 mm Thickness 226-3737

RS PRO 226-3737 Nitrile Rubber (NBR) Rotary Shaft Seal with a 20 mm inside diameter, 30 mm outside diameter, and 7 mm thickness offers an effective sealing solution for industrial, mechanical, and hydraulic systems. The seal is made from nitrile rubber, widely recognized for excellent resistance to oils, hydraulic fluids, and grease, making it ideal for driveshafts, crankshafts, and hydraulic cylinders requiring lubrication management. It is engineered to provide tight sealing of rotating shafts where leakage prevention is critical.

This seal is designed to maintain integrity under operating temperatures ranging from -20°C to 90°C, ensuring reliability in various environmental conditions. Its hardness of 70 ±5 shore A delivers durability and longevity under mechanical stress. The tensile strength of 18.9 MPa combined with high elongation at 438% ensures the material's capacity to stretch and recover without failure.

At a specific gravity of 1.25 g/cm³ and tear resistance of 58 N/mm, the seal resists mechanical wear and tear for enhanced service life. However, it is important to note that this NBR seal is incompatible with brake oils, phosphoric ester, and ester-based fluids, aligning its application scope to non-aggressive lubricants.

The product is suited for use in Industrial, Mechanical, Hydraulic, and Fluid Power applications. It delivers oil and grease resistance essential for rotating shaft sealing needs. Material properties are optimized for strength, flexibility, and durability.

Commonly used in maintenance and repair of machinery to prevent fluid leakage. Stock No. 226-3737 aids easy identification for procurement and inventory. RS PRO offers this seal with quality assurance meeting professional requirements. For more efficient equipment operation, select RS PRO NBR Seals per system specifications.
