RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 25 mm ID, 62 mm OD, 10 mm Thickness 226-3766

RS PRO 226-3766 is a nitrile rubber (NBR) rotary shaft seal designed to provide efficient sealing for rotating shafts with a 25 mm inside diameter, 62 mm outside diameter, and 10 mm thickness. This seal is engineered specifically for use in industrial and mechanical applications such as driveshafts, crankshafts, and hydraulic cylinders where lubrication oils or grease are present.

The nitrile rubber material is the cost-effective and commonly preferred choice for oil seals, offering high resistance to oils, hydraulic fluids, and grease, ensuring a long service life. It maintains sealing effectiveness in operational temperatures ranging from -20°C to 90°C.

Technical properties include a hardness rating of 70 ±5 shore A, tensile strength of 18.9 MPa, elongation at break at 438%, specific gravity of 1.25 ± 0.03 g/cm³, and a tear resistance of 58 N/mm. The black-colored seal is resilient and flexible to withstand mechanical stresses inherent to rotary shaft operation.

This NBR rotary shaft seal is not recommended for brake fluids or ester-based fluids such as phosphoric esters. Proper selection ensures reliable performance in standard industrial environments, including manufacturing, automotive repairs, and fluid power systems.

Constructed from nitrile rubber for oil and hydraulic fluid resistance. Designed for rotary shaft sealing with 25 mm ID and 62 mm OD dimensions. Works effectively within a temperature range from -20°C to 90°C. Hardness of 70 ±5 shore A ensures durability and flexibility.

High tear resistance and tensile strength deliver long service life. Set your operations for success with this high-quality RS PRO rotary shaft seal, ideal for fluid power and mechanical system maintenance.
