Product Description
RS PRO 226-3842 is a high-quality nitrile rubber (NBR) rotary shaft seal with 48 mm inside diameter, 62 mm outside diameter, and 8 mm thickness. It is engineered for industrial applications requiring reliable sealing against lubrication oils, hydraulic fluids, and grease to protect rotating shafts such as driveshafts, crankshafts, and hydraulic cylinders.
The NBR material provides excellent resistance to lubrication oils, hydraulic fluids, and grease while maintaining high durability and tear resistance of 58 N/mm. It has a hardness of 70 ± 5 Shore A, tensile strength of 18.9 MPa, and elongation capacity of 438%, making it suitable for dynamic sealing applications.
The recommended operating temperature range is from -20°C to 90°C, ensuring performance under various environmental conditions. The seal features a black color for ease of use in industrial settings.
This seal is not recommended for brake oils, phosphoric ester, or ester-based fluids to prevent material degradation and failure.
Manufactured in India, this RS PRO seal is ideal for mechanical, fluid power, and hydraulic applications across industrial, construction, manufacturing, and automotive sectors that require effective rotary shaft sealing solutions.
The seal's nitrile rubber composition offers cost-effective, dependable sealing against common industrial lubricants. Its dimensions provide compatibility with shafts requiring 48 mm ID and 62 mm OD sealing. The 8 mm thickness balances durability and flexibility for dynamic shaft operation.
Hardness and tensile strength values ensure mechanical robustness under operational stresses. Operating temperature tolerance enables use in diverse climates and machinery environments. Industry applications include driveshaft, crankshaft, and hydraulic cylinder sealing.
The seal promotes leakage prevention and prolongs machinery life through efficient lubrication retention. Explore more RS PRO seals and industrial Sealing solutions on EnvMart for premium quality and engineered reliability in your mechanical and hydraulic projects.
