Product Description
RS PRO 226-3732 is a high-quality Nitrile Rubber (NBR) rotary shaft seal engineered for effective sealing of rotating shafts with an inside diameter of 19 mm, outside diameter of 30 mm, and thickness of 7 mm. This seal is optimized for industrial, automotive, and hydraulic applications where resistance to lubrication oils, hydraulic fluids, and grease is critical.
The seal's robust nitrile material provides excellent resistance to oil and grease, making it ideal for use in driveshafts, crankshafts, and hydraulic cylinders. Its temperature tolerance from -20°C to 90°C enables reliable performance across a variety of working conditions.
The black color indicates standard nitrile composition with a hardness rating of 70 ± 5 shore A, combining durability with flexibility. The material features a tensile strength of 18.9 MPa and an elongation capacity of 438%, ensuring resilience under mechanical stress.
Other technical attributes include a specific gravity of approximately 1.25 g/cm³ and a tear resistance measuring 58 N/mm, supporting the seal's durability and operational longevity.
However, it should be noted this seal type is unsuitable for brake oil, phosphoric ester, and ester base fluids, which require different seal materials. Durable Nitrile Rubber (NBR) composition resists oil and grease degradation.
Rotary shaft seal designed for mechanical and hydraulic shafts. Operating temperature range from -20°C to 90°C. Hardness rating of 70 ± 5 shore A balances flexibility and strength. High tensile strength and elongation improve mechanical resilience.
Appropriate for automotive, industrial machinery, and hydraulic systems. Not suitable for brake oil or ester-based fluids.
This RS PRO seal complements a broad range of mechanical sealing solutions in industrial, automotive, and fluid power applications. Choosing the correct seal material and dimensions like the 19 mm ID and 30 mm OD ensures optimal machine performance and longevity.
