RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal 36 mm ID, 52 mm OD, 7 mm Thickness 226-3805

RS PRO 226-3805 is a high-quality Nitrile Rubber (NBR) Rotary Shaft Seal designed to provide reliable sealing performance in industrial mechanical applications. This seal features a 36 mm inside diameter, 52 mm outside diameter, and a 7 mm thickness, making it suitable for driveshafts, crankshafts, and hydraulic cylinders where rotating shafts require lubrication sealing.

Manufactured from nitrile rubber material, this seal ensures compatibility with common lubricants such as oils, hydraulic fluids, and grease, providing excellent resistance except for brake oil, phosphoric ester, and ester base applications. The seal's hardness is set at 70 ±5 Shore A, delivering a good balance between flexibility and durability.

The temperature operating range of the seal spans from -20°C to 90°C, allowing use in a wide range of environmental conditions. Mechanical properties include a tensile strength of 18.9 MPa and elongation of 438%, assuring flexibility and strength under operational stress. The specific gravity is approximately 1.25 g/cm³ and tear resistance at 58 N/mm further contribute to a robust seal life.

Typical industrial applications for this RS PRO seal include uses in hydraulic systems, automotive machinery, heavy equipment, and other fluid power tools requiring dependable shaft sealing to prevent leaks and contamination. Its black color and standard dimensions allow easy integration into existing assemblies.

This seal is part of RS PRO’s extensive range of cost-effective, highly reliable seals made to withstand industrial mechanical wear and chemical exposure. Perfect for maintenance and production operations in manufacturing, automotive repair, and industrial machinery sectors.

Constructed from durable nitrile rubber resistant to oil, grease, and hydraulic fluids. Seal dimensions of 36 mm ID, 52 mm OD, and 7 mm thickness ensure proper fitment for rotary shafts. Hardness of 70 ±5 Shore A supports reliable sealing under pressure and movement.

Operates reliably between -20°C and 90°C temperature extremes. High tensile strength and elongation provide robustness against mechanical stress. Tear resistance enhances lifespan in demanding seal environments. Ideal for industrial, automotive, hydraulic, and fluid power sealing applications.
