RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 58 mm ID, 72 mm OD, 8 mm Thickness 226-3869

RS PRO 226-3869 Nitrile Rubber (NBR) Rotary Shaft Seal features an inside diameter of 58 mm, outside diameter of 72 mm, and thickness of 8 mm. This seal material is widely used in industrial environments for reliable sealing of rotating shafts. The nitrile rubber composition offers excellent resistance against lubrication oils, hydraulic fluids, and grease, making it suitable for driveshafts, crankshafts, and hydraulic cylinder applications where effective fluid containment and dust exclusion are critical.

The seal operates efficiently within a temperature range of -20°C to 90°C, ensuring consistent performance in moderate industrial conditions. The seal's hardness of 70 ±5 Shore A and tensile strength of 18.9 MPa provide mechanical robustness, while its elongation of 438% allows for flexibility and adaptability to shaft movements. With a specific gravity near 1.25 g/cm³ and tear resistance of 58 N/mm, this product promises durability and long service life in demanding environments.

Designed for industrial, mechanical, fluid power, and construction machinery applications, RS PRO 226-3869 ensures precise sealing, reducing leakage and contamination risks. The seal is black in color, optimized for standard rotary shaft configurations and is not recommended for exposure to brake oil, phosphoric ester, or ester base fluids.

The seal is made from durable nitrile rubber (NBR) material providing resistance to lubrication oils and hydraulic fluids. Seal thickness is 8 mm ensuring proper fit and sealing performance. Suitable for use in driveshafts, crankshafts, and hydraulic cylinders requiring oil or grease lubrication.

Operating temperature range is from -20°C to 90°C for versatile industrial applications. Hardness of the seal is 70 ±5 Shore A with tensile strength of 18.9 MPa ensuring durability and strength. Elongation at break is 438% providing flexibility during operation.

Specific gravity approximately 1.25 g/cm³ contributing to optimal seal weight and performance. Tear resistance is 58 N/mm making the seal resistant to mechanical wear.

This seal is a cost-effective solution for industrial fluid sealing needs and widely used in environments requiring reliability and resistance to common lubricants. Explore more sealing solutions in the Mechanical Machinery & Spares category on EnvMart for your industrial requirements.
