Product Description

RS PRO 226-3741 rotary shaft seal is a precision-engineered component made from nitrile rubber (NBR), widely regarded as a cost-effective and reliable material for sealing solutions. The seal is designed with a 20 mm inside diameter, 38 mm outside diameter, and an 8 mm thickness optimized for rotating shafts and applications requiring effective sealing against lubrication oils, hydraulic fluids, and grease.

This seal finds applications in industrial machinery including driveshafts, crankshafts, and hydraulic cylinders. The material's resistance properties make it unsuitable for brake oils, phosphoric ester, and ester base fluids; however, its compatibility with common lubrication environments is highly valued.

The operating temperature range of -20°C to 90°C allows use across diverse industrial environments without compromising performance. The seal's hardness is rated at 70 ±5 shore A, ensuring it maintains structural integrity under mechanical stress. Its tensile strength of 18.9 MPa combined with an elongation at break of 438% provides a flexible yet strong sealing solution.

Specific density approximates 1.25 g/cm³, indicative of the dense, durable nature of the nitrile rubber compound. Tear resistance measured at 58 N/mm guarantees durability against mechanical wear in demanding applications. The seal is finished in black color, standard for oil Seals for easy identification and compatibility.

The seal material is nitrile rubber, offering resistance to lubrication oils, hydraulic fluids, and grease. Designed for use in driveshafts, crankshafts, and hydraulic cylinders. Operating temperature range: -20°C to 90°C.

Hardness of 70 ±5 shore A. Tensile strength: 18.9 MPa and elongation: 438%. Specific gravity approximately 1.25 g/cm³. Tear resistance: 58 N/mm.
