RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 25 mm ID, 52 mm OD, 10 mm Thickness 226-3763

RS PRO 226-3763 Nitrile Rubber (NBR) Rotary Shaft Seal with 25 mm inside diameter, 52 mm outside diameter, and 10 mm thickness is a high-quality sealing solution for industrial and mechanical applications. This seal is engineered from nitrile rubber known for its excellent resistance to lubrication oils, hydraulic fluids, and grease, making it ideal for driveshafts, crankshafts, and hydraulic cylinders where rotating shafts require reliable lubrication containment.

The seal operates effectively within a temperature range of -20°C to 90°C, supporting a wide range of environmental conditions in industrial operations. Its material hardness of 70 ±5 Shore A provides mechanical toughness while maintaining flexibility with an elongation rate of 438%. The tensile strength of 18.9 MPa and tear resistance of 58 N/mm ensure durability and long service life under demanding conditions. The specific gravity of 1.25 ±0.03 g/cm³ defines the material density contributing to overall performance.

This NBR seal is not suitable for use with brake oil, phosphoric ester, or ester base fluids, but excels in most common lubrication environments found in power transmission and hydraulic systems. Its black color enhances detection and installation accuracy. The seal is an essential component for industrial, automotive, and manufacturing sectors requiring dependable shaft sealing for rotating machinery parts.

Constructed from nitrile rubber (NBR) for optimal oil and grease resistance. Designed for rotary shaft sealing applications with precise 25 mm ID and 52 mm OD. 10 mm thickness for secure and effective sealing against leaks.
