Product Description

RS PRO 226-3806 is a rotary shaft seal crafted from nitrile rubber (NBR), highly effective in industrial sealing applications requiring oil resistance. Its detailed dimensions of 37 mm inside diameter, 52 mm outside diameter, and 8 mm thickness make it suitable for various mechanical systems such as driveshafts, crankshafts, and hydraulic cylinders.

The nitrile rubber (NBR) compound used in this seal offers excellent resistance to lubrication oils, hydraulic fluids, and grease, making it ideal for machinery components exposed to these substances. It features a hardness rating of 70 ±5 shore A for toughness and a tensile strength of 18.9 MPa, combined with an elongation of 438%, which provides the balance between flexibility and durability necessary for effective sealing.

This seal operates reliably within a temperature range of -20°C to 90°C, allowing use in a variety of industrial environments without degradation. Its tear resistance rating of 58 N/mm ensures resilience against mechanical wear and prolongs service life. The specific gravity value of 1.25 ± 0.03 g/cm³ confirms the material density optimized for sealing functions.

Typical applications include sealing of rotating shafts in hydraulic cylinders, driveshafts, and crankshafts where oil or grease is present, ensuring lubrication retention and prevention of contamination ingress. This seal is unsuitable for brake oil, phosphoric ester, and ester base fluids.

RS PRO brand is recognized for cost-effective and reliable industrial sealing solutions, ensuring operational efficiency and durability. This product is ideal for industries such as automotive, manufacturing, hydraulics, and general machinery maintenance requiring high performance rotary shaft seals.

The seal measures 37 mm ID and 52 mm OD. Thickness of 8 mm for strong sealing capability. Material: Nitrile Rubber (NBR) for oil-resistant applications. Operating temperature between -20°C and 90°C. Hardness rating of 70 ±5 shore A.

Tensile strength 18.9 MPa and elongation of 438%. Tear resistance: 58 N/mm for durability. Explore more RS PRO Sealing solutions and mechanical spare parts in the EnvMart Industrial Tools & Equipment category.
