RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 20 mm Inside Diameter, 28 mm Outside Diameter, 6 mm Thickness 226-3734

RS PRO 226-3734 is a premium Nitrile Rubber (NBR) Rotary Shaft Seal engineered for industrial use, comprising a 20 mm inside diameter, 28 mm outside diameter, and 6 mm thickness. This seal is ideal for applications including driveshafts, crankshafts, and hydraulic cylinders where reliable sealing against lubrication oils, hydraulic fluids, and grease is critical.

The NBR material delivers cost efficiency while maintaining excellent mechanical properties such as a hardness rating of 70 ±5 Shore A, a tensile strength of 18.9 MPa, and 438% elongation. The seal performs optimally in operating temperatures ranging from -20°C to 90°C, ensuring versatility across diverse industrial environments.

Not recommended for use with brake oil, phosphoric ester, or ester-based fluids; however, its compatibility with common lubricants enhances its suitability for hydraulic and automotive machinery. The seal's specific gravity of 1.25 g/cm³ balances density for functional performance, while its tear resistance of 58 N/mm guarantees robust protection against mechanical wear.

This RS PRO rotary shaft seal is suitable for manufacturing, maintenance, automotive repair, and hydraulic systems in industrial, construction, and mechanical fluid power sectors. It contributes to efficient sealing solutions that prevent fluid leakage and contamination, thus improving equipment reliability and lifespan.

Constructed from nitrile rubber (NBR), a widely used oil-resistant elastomer. Designed for rotary shaft sealing applications requiring oil and grease resistance. Dimensions provide compatibility with shafts requiring 20 mm ID and 28 mm OD seals.

Operates reliably within a broad temperature range of -20°C to 90°C. Exhibits mechanical durability with high tensile strength and elongation properties. Offers tear resistance for durability under dynamic shaft motion. Ideal for applications in automotive, industrial machinery, and hydraulic equipment.
