Product Description
RS PRO 226-3778 Nitrile Rubber (NBR) Rotary Shaft Seal features a 30 mm inside diameter, 47 mm outside diameter, and 8 mm thickness. It is crafted from nitrile rubber material known for its strong resistance to lubrication oils, hydraulic fluids, and grease, making it suitable for industrial, automotive, hydraulic, and fluid power applications.
This oil seal is extensively used in driveshafts, crankshafts, and hydraulic cylinders where oil or grease lubrication prevents wear on rotating shafts. Its operational temperature range spans from -20°C to 90°C ensuring robust performance under various environmental conditions.
The material hardness is rated at 70 ±5 Shore A, coupled with a tensile strength of 18.9 MPa and an elongation of 438%, highlighting its flexibility and mechanical endurance. Specific gravity is approximately 1.25 g/cm³, while tear resistance of 58 N/mm contributes to durability in demanding operational settings.
The nitrile oil seal should not be used with brake oil, phosphoric ester, or ester-based fluids because it lacks compatibility with these chemicals. Manufactured from cost-effective nitrile rubber material commonly used in rotary shaft sealing.
Designed for use in driveshafts, crankshafts, and hydraulic cylinders. Protects shafts by retaining lubrication oils and preventing contaminants ingress. Operating temperature range: -20°C to 90°C suitable for varied industrial environments.
Hardness of 70 ±5 Shore A ensures resilience and long service life. Tensile strength: 18.9 MPa provides mechanical robustness. High elongation: 438% offers flexibility during operation. Specific gravity: 1.25 g/cm³ reflects material density and stiffness.
Tear resistance: 58 N/mm resists mechanical damage and wear.
This rotary shaft seal is essential for applications in industrial machinery, automotive components, hydraulic systems, and fluid power equipment where oil and grease sealing is critical.
