RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 20 mm Inside Diameter, 35 mm Outside Diameter, 6 mm Thickness 226-3739

RS PRO 226-3739 Nitrile Rubber (NBR) Rotary Shaft Seal delivers dependable sealing performance with precise dimensions of 20 mm inside diameter, 35 mm outside diameter, and 6 mm thickness. Manufactured from high-quality nitrile rubber, this seal is well-suited for industrial, mechanical, and fluid power applications requiring resistance to oils and greases.

Commonly used in driveshafts, crankshafts, and hydraulic cylinders, this rotary shaft seal effectively prevents lubricant leakage and contamination ingress, helping maintain the longevity and efficiency of rotating equipment components. The nitrile material offers excellent resistance against lubrication oils, hydraulic fluids, and grease while being unsuitable for brake oils and phosphoric ester based fluids.

Operating reliably within a temperature range from -20°C to 90°C, this seal's material hardness of 70 ±5 Shore A balances flexibility with wear resistance for demanding industrial environments. It has a tensile strength of 18.9 MPa and an elongation capability of 438%, providing robust mechanical properties and resilience during dynamic operation.

The seal's specific gravity of 1.25 ±0.03 g/cm³ indicates consistent material density, contributing to its performance stability. Additionally, a tear resistance of 58 N/mm ensures durability against mechanical stresses and wear over time.

Ideal for usage in automotive, manufacturing, hydraulic, and fluid power industries, this RS PRO nitrile rubber seal ensures efficient sealing to prevent fluid leakage and protect moving parts from contaminants. This item is supplied new and ready for immediate installation.
