TIMKEN 309KG BEARING

Description:

The Timken 309KG is a single-row deep groove radial ball bearing from the Timken Fafnir® 300 Series. Featuring an open design, this bearing is engineered to support primarily radial loads along with moderate axial loads in both directions while delivering smooth, low-friction operation at high speeds. It is commonly used in electric motors, pumps, gearboxes, conveyors, fans, compressors, agricultural equipment, and general industrial machinery requiring reliable rotational performance.

Applications:

The Timken 309KG deep groove ball bearing is designed for industrial applications requiring high-speed operation, low friction, and long service life. Its Conrad deep-groove design enables it to handle radial loads and moderate thrust loads from either direction, making it suitable for electric motors, industrial pumps, conveyors, machine tools, fans, compressors, and power transmission equipment.
