Product Description
RS PRO 226-3875 Nitrile Rubber (NBR) Rotary Shaft Seal is engineered for industrial and mechanical applications requiring reliable sealing solutions. With a precise inside diameter of 60 mm, outside diameter of 85 mm, and thickness of 8 mm, this seal ensures tight sealing around rotating shafts such as driveshafts, crankshafts, and hydraulic cylinders where lubrication oils or greases are used.
The NBR material is the most cost-effective choice for oil seals due to its excellent resistance to oils, hydraulic fluids, and grease, making it widely suitable across fluid power and mechanical engineering industries. It is not recommended for brake oil, phosphoric ester, or ester base fluids.
The seal’s physical properties include a Shore A hardness of 70 ±5 for optimal flexibility and durability, tensile strength of 18.9 MPa for mechanical integrity, and remarkable elongation capacity of 438% that allows apt deformation without failure. The black coloration follows common industrial standards for oil and rotary shaft seals.
Operating temperature ranges from -20°C to 90°C allow use in a variety of environments with non-extreme thermal requirements. The specific gravity of 1.25 ± 0.03 g/cm³ provides insight into material density and behavior. Tear resistance at 58 N/mm contributes to the durability of this seal under mechanical stresses.
Durable Nitrile Rubber material provides oil and grease resistance. Rotary shaft design fits common industrial rotating machinery components. Temperature range suitable for typical industrial environments. Physical properties ensure mechanical strength and flexibility.
Black color standard for industrial oil seals. Used in mechanical, hydraulic, and fluid power applications.
This RS PRO seal is supplied as a new product meeting standard quality requirements and is ideal for maintenance and repair operations. For more options in Seals and industrial components, explore our extensive RS PRO product line on EnvMart.
