SKF Self-Aligning Ball Bearing 30 mm Inside Diameter 72 mm Outside Diameter 19 mm Race Width Non-Metallic Cage 1306 ETN9/C3

The SKF 1306 ETN9/C3 self-aligning ball bearing is designed with two rows of steel balls housed within a non-metallic cage. It features a 30 mm inside diameter and a 72 mm outside diameter, with a race width of 19 mm. This bearing type has an open end design, facilitating inspection and maintenance of the bearing in industrial applications.

Engineered to accommodate angular misalignment, this self-aligning bearing includes a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. This construction allows the bearing to function efficiently in conditions where shaft deflection or slight misalignments may occur, making it ideal for use in machinery subject to shaft bending or mounting errors.

The C3 internal clearance provides additional space inside the bearing, which compensates for thermal expansion during operation, thus improving service life and reliability in high-speed or high-temperature environments. Its limiting speed rating of 13000 rpm allows it to be used in applications requiring high rotational speeds.

Typical uses include industrial machinery, manufacturing equipment, and fluid power systems where robust load capacity and precision in rotation are critical. The steel balls ensure high static load rating of 6.8 kN and dynamic load rating of 22.5 kN, lending to durability and performance in demanding environments.

The bearing’s parallel bore and cylindrical design make it suitable for installation on shafts requiring precise fit. Non-metallic cage reduces weight and prevents corrosion, enhancing the bearing’s operational life. Self-aligning feature protects machinery from damage due to misalignment or shaft flexing.

Manufactured to SKF’s strict quality control standards in Malaysia, ensuring reliability and consistent performance. Ideal for various sectors including industrial automation, manufacturing, HVAC systems, and mechanical power transmission.
