RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 40 mm ID 52 mm OD 7 mm 226-3813

RS PRO 226-3813 is a nitrile rubber (NBR) rotary shaft seal engineered for reliable sealing of rotary shafts in various mechanical assemblies. It measures 40 mm inside diameter (ID), 52 mm outside diameter (OD), and has a thickness of 7 mm, making it suitable for driveshafts, crankshafts, and hydraulic cylinders.

The seal's nitrile rubber construction provides excellent resistance to common lubricants such as oils, hydraulic fluids, and grease, enhancing its durability in demanding industrial environments. However, it is not suitable for exposure to brake fluids, phosphoric esters, or ester-based fluids.

Designed to operate within a temperature range of -20°C to 90°C, this seal withstands moderate thermal stresses. Its hardness of 70 ±5 Shore A ensures a tight seal without compromising flexibility, while its tensile strength of 18.9 MPa and elongation capability of 438% provide resilience against mechanical stresses.

Additional physical properties include a specific gravity of 1.25 ± 0.03 g/cm³, contributing to its consistent performance and durability, and a tear resistance of 58 N/mm for long-lasting service life. The black color finish is typical for industrial-grade seals.

This RS PRO nitrile rubber seal is crafted in India under new product condition standards, assuring quality and consistency for industrial, mechanical, hydraulic, and manufacturing applications. Its robust design makes it a reliable component for sealing rotating shafts, preventing contamination, and retaining lubricants.

Made from nitrile rubber (NBR) material offering effective resistance to lubrication oils, hydraulic fluids, and grease. Ideal for use in driveshafts, crankshafts, and hydraulic cylinders. Operates reliably in temperature ranges from -20°C to 90°C.

Features a hardness rating of 70 ±5 Shore A for durability. High tensile strength of 18.9 MPa and elongation of 438% for robust performance. Specific gravity of 1.25 ± 0.03 g/cm³ and tear resistance of 58 N/mm. Color is black to suit industrial applications.
