RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 45 mm Inside Diameter, 75 mm Outside Diameter, 10 mm Thickness 226-3839

RS PRO 226-3839 Nitrile Rubber (NBR) rotary shaft seal is engineered for sealing rotating shafts in mechanical and fluid power applications. It features a 45 mm inside diameter, 75 mm outside diameter, and 10 mm thickness, making it compatible with a wide range of equipment such as driveshafts, crankshafts, and hydraulic cylinders where oil or grease lubrication is involved.

The seal material is nitrile rubber (NBR), valued for its resistance to lubrication oils, hydraulic fluids, and grease, which makes it suitable for industrial machinery maintenance and repair. It is not recommended for brake oils or phosphoric ester fluids.

Operating temperature ranges from -20°C to 90°C allow the seal to function effectively in typical industrial environments. The material hardness of 70 ±5 Shore A provides a good balance of flexibility and durability.

With a tensile strength of 18.9 MPa and elongation of 438%, the seal offers excellent mechanical resistance and elasticity. Its specific gravity of 1.25 g/cm³ reflects a dense, durable compound, while tear resistance of 58 N/mm ensures reliability under mechanical stress.

This seal is ideal for use in industrial sectors including manufacturing, automotive maintenance, hydraulics, and fluid power systems, enhancing equipment longevity and performance by preventing fluid leaks and contamination.

The seal is made from cost-effective nitrile rubber (NBR) material providing excellent resistance to oils and grease. It features a rotary shaft design suitable for driveshafts, crankshafts, and hydraulic cylinders. Operating temperature ranges from -20°C up to 90°C, ideal for various industrial environments.

Hardness measured at 70 ±5 Shore A ensures durability and effective sealing performance. High tensile strength of 18.9 MPa with elongation up to 438% guarantees material flexibility. Specific gravity is approximately 1.25 ± 0.03 g/cm³, indicating robust material density.

Tear resistance at 58 N/mm helps withstand mechanical stress and wear. Reliable sealing solutions like the RS PRO 226-3839 ensure reduced equipment downtime and maintenance costs in mechanical, fluid power, automotive, and hydraulic industries.
