RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 50 mm Inside Diameter, 80 mm Outside Diameter, 10 mm Thickness 226-3854

RS PRO 226-3854 Nitrile Rubber (NBR) Rotary Shaft Seal is a precision-engineered seal designed for mechanical and fluid power applications requiring effective sealing on rotating shafts. This seal features an inside diameter of 50 mm, an outside diameter of 80 mm, and a thickness of 10 mm, providing a secure fit for shafts and housings in various industrial equipment.

Constructed from nitrile rubber, the seal offers excellent resistance against lubrication oils, hydraulic fluids, and greases commonly found in driveshafts, crankshafts, and hydraulic cylinder environments. The black nitrile compound balances durability with flexibility, achieving a shore hardness of 70 ±5 Shore A. This allows the seal to maintain its shape and seal integrity during operation.

Designed to operate within a temperature range of -20°C to 90°C, this seal is suitable for a wide array of applications including automotive, hydraulic systems, and industrial machinery where rotating shaft sealing is crucial. With a tensile strength of 18.9 MPa and an elongation at break of 438%, it delivers high mechanical resilience and longevity under dynamic conditions.

The seal’s specific gravity of 1.25 ± 0.03 g/cm³ indicates consistent material density, while its tear resistance value of 58 N/mm ensures durability against mechanical wear and stresses. It is important to note that this seal is not compatible with brake oils, phosphoric ester, and ester-based fluids due to material limitations.
