RS PRO Nitrile Rubber Rotary Shaft Seal, 30 mm ID, 62 mm OD, 7 mm Thickness 226-3787

RS PRO 226-3787 Nitrile Rubber (NBR) Rotary Shaft Seal features a 30 mm inside diameter, 62 mm outside diameter, and 7 mm thickness, designed for efficient sealing in mechanical and fluid power applications. The seal material, Nitrile Rubber, is well-known for its resistance to oils, hydraulic fluids, and grease, making it suitable for use in driveshafts, crankshafts, and hydraulic cylinders that involve oil or grease lubrication.

This seal can operate reliably within a temperature range of -20°C to 90°C, ensuring performance across diverse environments. The 70 ± 5 Shore A hardness provides a balanced toughness and flexibility to withstand wear and tear.

Enhanced mechanical properties such as 18.9 MPa tensile strength and 438% elongation indicate the seal’s capability to endure mechanical stresses while maintaining elasticity. The material also exhibits a specific gravity of 1.25 ± 0.03 g/cm³ and tear resistance of 58 N/mm, signaling quality and durability during usage.

Due to these characteristics, this RS PRO 226-3787 seal is a preferred choice in industrial and mechanical setups requiring reliable rotary shaft sealing solutions. However, it is unsuitable for brake oil, phosphoric ester, and ester base fluids.

The seal material is Nitrile Rubber (NBR) which balances cost with performance. Seal dimensions provide compatibility with common shaft sizes for mechanical and hydraulic equipment. Operating temperature range supports applications in moderate thermal environments.

High tensile strength and elongation provide excellent mechanical endurance. Suitable for industrial, manufacturing, and fluid power sealing needs.
