RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 45mm ID, 85mm OD, 10mm Thickness 226-3841

RS PRO 226-3841 Nitrile Rubber Rotary Shaft Seal is engineered for high-performance sealing in mechanical and fluid power systems. Featuring a 45 mm inside diameter, 85 mm outside diameter, and 10 mm thickness, this seal is specifically designed for rotary shaft applications in machinery and equipment.

The high-quality Nitrile Rubber (NBR) material provides excellent resistance to lubrication oils, hydraulic fluids, and grease, making it an effective and versatile choice for driveshafts, crankshafts, and hydraulic cylinders where rotating shafts require reliable lubrication maintenance and protection from oil contamination.

Manufactured from high-quality Nitrile Rubber (NBR) for durability and resistance to oils, hydraulic fluids, and greases. 45 mm inner diameter and 85 mm outer diameter ensures excellent fitment for rotary shaft applications.

10 mm thickness provides robust sealing performance and longevity in industrial environments. Designed as a rotary shaft seal ideal for driveshafts, crankshafts, and hydraulic cylinders. Operating temperature range from -20°C to 90°C for versatile use in demanding conditions.

Hardness rating of 70 ±5 Shore A enhances mechanical stability and wear resistance. Tensile strength of 18.9 MPa ensures reliability under mechanical stress. Specific gravity of 1.25 ± 0.03 g/cm³ for precise material consistency.

Elongation of 438% and tear resistance of 58 N/mm indicate high resilience and durability. Black color seal with a professional finish suitable for multiple industrial sealing applications.

Thanks to its excellent physical properties, including a hardness rating of 70 ±5 Shore A and tensile strength of 18.9 MPa, the seal maintains integrity under demanding mechanical conditions. Its elongation of 438% and tear resistance of 58 N/mm allow for sustained resilience during installation and operation.

This seal operates efficiently within a temperature range of -20°C to 90°C, supporting a wide array of industrial, construction, and fluid management applications. It is not recommended for use with brake oil, phosphoric ester, or ester base fluids. The black finish ensures visually identifiable installation and professional appearance.

Industrial applications include hydraulic cylinder sealing, driveshaft protection, crankshaft oil retention, manufacturing machinery maintenance, and fluid power systems. It is especially useful in environments requiring long-term reliability for rotating parts and machinery.
