Product Description

RS PRO 226-3758 is a high-quality nitrile rubber (NBR) rotary shaft seal engineered for efficient sealing of rotating shafts in various industrial applications. This seal measures 25 mm inside diameter, 40 mm outside diameter, and 5 mm thickness, ensuring an accurate and reliable fit for sealing oil or grease around rotating components.

The nitrile rubber material used in this seal is highly resistant to many types of lubrication oils, hydraulic fluids, and grease, making it suitable for use in driveshafts, crankshafts, and hydraulic cylinders where reliable sealing is critical. Due to its material properties, this seal is not suitable for brake oils or phosphoric ester fluids.

Operating reliably across a temperature range of -20°C to 90°C, the seal features a hardness rating of 70 ±5 Shore A, tensile strength of 18.9 MPa, and elongation capacity of 438%, providing durability and flexibility required in demanding industrial environments. Its tear resistance of 58 N/mm adds to its robust construction.
