Product Description

RS PRO 226-3756 Nitrile Rubber (NBR) Rotary Shaft Seal features a 25 mm inside diameter, 38 mm outside diameter, and 7 mm thickness, engineered to provide effective sealing solutions in mechanical and hydraulic systems.

Manufactured with high-quality nitrile rubber material, this seal offers excellent resistance to lubrication oils, hydraulic fluids, and grease, making it ideal for use in driveshafts, crankshafts, and hydraulic cylinders where reliable sealing of rotating shafts is crucial.

The operating temperature range from -20°C to 90°C allows for stable performance in diverse industrial conditions. The seal’s hardness is rated at 70 ±5 Shore A, balancing flexibility with wear resistance. It has a tensile strength of 18.9 MPa and elongation capability of 438%, ensuring durability and elasticity during operation.

With a specific gravity of 1.25 ± 0.03 g/cm³ and tear resistance of 58 N/mm, the seal performs reliably under mechanical stress. Its black color complies with common standards for sealing components.

The seal material is nitrile rubber (NBR) suitable for industrial rotary shaft sealing applications. Dimensions include 25 mm inside diameter, 38 mm outside diameter, and 7 mm thickness for precise fitment. Designed for use in mechanical, fluid power, and hydraulic systems requiring robust sealing performance.

Resistant to oil, grease, and hydraulic fluids but not compatible with brake oil or phosphoric ester fluids. Operating temperature range from -20°C to 90°C accommodates typical industrial environments. Hardness, tensile strength, elongation, specific gravity, and tear resistance values ensure long service life.

This product is ideal for industrial applications including construction machines, manufacturing equipment, automotive driveshafts, and agricultural machinery that require reliable sealing against fluid leakage.
