RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 8 mm ID, 16 mm OD, 7 mm Thickness 226-3897

RS PRO 226-3897 Nitrile Rubber (NBR) Rotary Shaft Seal is engineered for high-performance sealing applications where reliable resistance to lubrication oils, hydraulic fluids, and grease is required. This seal, measuring 8 mm inside diameter, 16 mm outside diameter, and 7 mm thickness, is commonly used in driveshafts, crankshafts, and hydraulic cylinders that involve rotating shafts.

The nitrile rubber material provides excellent mechanical properties including a hardness of 70 ±5 Shore A, tensile strength of 18.9 MPa, and elongation at break of 438%, delivering resilience and long service life. The seal operates effectively within a temperature range of -20°C to 90°C, making it suitable for diverse industrial and mechanical environments.

With a specific gravity of 1.25 ± 0.03 g/cm³ and a tear resistance rating of 58 N/mm, this seal ensures reliable sealing performance to prevent fluid leakage and contamination. The black color conforms with standard oil seal appearances, facilitating installation and identification.
