SKF 2308 ETN9

SKF 2308 ETN9 Self-Aligning Ball Bearing Description The SKF 2308 ETN9 is a double-row self-aligning ball bearing, designed to accommodate misalignment of the shaft relative to the housing. It has very low friction, making it suitable for running at higher speeds than any other type of rolling bearing. This component is part of SKF’s Explorer class, featuring an optimized internal design for enhanced performance. Specifications Bore Diameter (d): 40 mm Outer Diameter (D): 90 mm Width (B): 33 mm Basic Dynamic Load Rating: 32.5 kN Basic Static Load Rating: 11.2 kN Limiting Speed: 9000 r/min Cage: Glass fibre reinforced PA66 (Polyamide) Bore Type: Cylindrical Label Info Manufacturer: SKF Model: 2308 ETN9 EAN: 7316576638251 Application Ideal for use in applications such as agricultural machinery, fans, industrial gearboxes, and food processing equipment where shaft deflection or mounting errors are expected. Country of Origin Made in Sweden. CO2 Impact Opting for this pre-owned component saves an estimated 1.9 kg of CO2 compared to manufacturing a new one, contributing to a more sustainable industrial process.

The ‘E’ indicates an optimized internal design for higher load-carrying capacity. The ‘TN9′ specifies that the bearing has a snap-type cage made of glass fibre reinforced polyamide 6,6, which is ball centred. This material offers a good balance of strength, elasticity, and thermal stability. Can this bearing be used in high-temperature environments? The polyamide cage (TN9) has a continuous operating temperature limit of up to 120 deg C (250 deg F). For applications with consistently higher temperatures, a bearing with a steel cage (e.g., suffix M) would be a more suitable choice. What is the maximum permissible angular misalignment for the 2308 ETN9? A self-aligning ball bearing like the 2308 ETN9 can typically accommodate static misalignment of approximately 2.5 to 3 degrees. However, the permissible dynamic misalignment under load will be smaller and depends on the specific operating conditions. Always consult the SKF engineering manual for precise limits based on your application’s load and speed.
