Product Description
RS PRO 226-3746 is a high-quality nitrile rubber (NBR) rotary shaft seal designed to provide reliable sealing solutions in mechanical systems. This seal features a 20 mm inside diameter and a 47 mm outside diameter with a 7 mm thickness, making it ideal for sealing rotating shafts in hydraulic cylinders, driveshafts, and crankshafts lubricated by oil or grease.
Constructed from nitrile rubber, known for its cost-effectiveness and wide availability, this seal offers excellent resistance to oils, hydraulic fluids, and grease, but is not suitable for brake oil or phosphoric ester-based fluids. The operating temperature range spans from -20°C to 90°C, allowing for versatile performance across industrial and automotive applications.
The seal exhibits a hardness rating of 70 ±5 Shore A, combined with a tensile strength of 18.9 MPa and a high elongation rate of 438%, ensuring both durability and flexibility to maintain a secure fit under mechanical stress. With a tear resistance of 58 N/mm and a specific gravity of 1.25 ±0.03 g/cm³, this product stands up to demanding operating conditions.
Applications include use in mechanical assemblies where rotary shaft seals are critical to prevent leakage of lubricants and contaminants, enhancing equipment reliability in industrial machinery, automotive, and hydraulic systems.
Durable nitrile rubber (NBR) construction for oil and grease resistance. Precision dimensions: 20 mm ID, 47 mm OD, and 7 mm thickness. Suitable for rotary shafts in driveshafts and hydraulic cylinders. Robust tensile strength and elongation for mechanical resilience.
