RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 28 mm Inside Diameter, 47 mm Outside Diameter, 7 mm Thickness 226-3772

RS PRO 226-3772 Nitrile Rubber (NBR) Rotary Shaft Seal is engineered for industrial, mechanical, and fluid power applications, providing an effective sealing solution for rotating shafts such as driveshafts, crankshafts, and hydraulic cylinders that operate with lubricating oils or grease.

Constructed from cost-effective nitrile rubber (NBR), this seal offers excellent resistance to lubrication oils, hydraulic fluids, and grease, ensuring prolonged service life in demanding environments. It features an inside diameter of 28 mm, outside diameter of 47 mm, and thickness of 7 mm to fit precise shaft specifications.

The seal maintains its integrity under operating temperatures ranging from -20°C to 90°C. Its hardness rating of 70 ±5 Shore A provides robustness and durability against mechanical wear. The seal exhibits a tensile strength of 18.9 MPa and elongation at break of 438%, offering a balance of strength and flexibility, while a specific gravity close to 1.25 g/cm³ and tear resistance of 58 N/mm highlight its resilience.

While effective against common oils and greases, this nitrile seal is unsuitable for use with brake oil, phosphoric ester, or ester base fluids. The black seal color simplifies identification in industrial settings.

Made from high-quality nitrile rubber (NBR) for strong, oil-resistant sealing. Designed specifically for rotating shaft applications such as driveshafts and hydraulic cylinders. Dimensioned precisely to 28 mm ID, 47 mm OD, and 7 mm thickness.

Operates effectively within -20°C to 90°C temperature range. Balances hardness and flexibility with 70 ±5 Shore A hardness and 438% elongation.

Suitable for industrial, manufacturing, mechanical maintenance, automotive, and hydraulic equipment applications. Enhance your equipment reliability with RS PRO Seals, available through EnvMart's extensive industrial tools category.
