RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 24 mm ID 40 mm OD 7 mm Thickness 226-3751

RS PRO 226-3751 Nitrile Rubber (NBR) Rotary Shaft Seal features a 24 mm inside diameter (ID), 40 mm outside diameter (OD), and 7 mm thickness, engineered for industrial and mechanical sealing needs.

This seal is constructed from nitrile rubber, the most cost-effective and widely used material for oil seals. It exhibits excellent resistance to lubrication oils, hydraulic fluids, and grease, making it ideal for applications such as driveshafts, crankshafts, and hydraulic cylinders with rotating shafts contacting oils or grease.

The seal operates reliably between temperatures of -20°C and 90°C and maintains a shore hardness of 70 ±5, providing a balance between flexibility and hardness. With a tensile strength of 18.9 MPa and elongation of 438%, the seal can withstand mechanical stresses and accommodate shaft motion effectively.

The specific gravity of approximately 1.25 g/cm³ ensures consistent density, while the tear resistance of 58 N/mm enhances its durability and lifespan under demanding operating conditions.

Its black color and rotary shaft seal design complement a broad array of mechanical systems requiring efficient sealing to prevent lubricant leakage and ingress of contaminants. Made from nitrile rubber (NBR) material for strong resistance to oils and greases.

Suitable for use on rotating shafts such as driveshafts, crankshafts, and hydraulic cylinders. Operating temperature range from -20°C to 90°C ensuring performance stability. Seal hardness of 70 ±5 shore A for durable and flexible sealing.

High tensile strength of 18.9 MPa providing mechanical robustness. Elongation capacity of 438% to accommodate shaft movement. Specific gravity approx. 1.25 g/cm³ contributing to consistent material density. Tear resistance rated at 58 N/mm for enhanced wear protection.

This seal is suitable for industrial equipment, fluid power systems, mechanical machinery, and hydraulic applications where reliable sealing is critical to system performance and longevity.
