Timken 313KDD Radial Deep Groove Ball Bearing 65MM Bore 140MM OD

Description:

The Timken 313KDD is a single-row deep groove radial ball bearing from the Timken Fafnir® 300 Series. Featuring double metal shields (KDD), this bearing is designed to support primarily radial loads with moderate axial loads in both directions while protecting the rolling elements from contaminants and retaining lubricant. With a 65 mm bore and 140 mm outside diameter, it is commonly used in electric motors, pumps, conveyors, gearboxes, fans, compressors, agricultural equipment, and other industrial rotating machinery requiring reliable, low-friction operation.

Applications:

The Timken 313KDD deep groove ball bearing is engineered for high-performance industrial applications requiring smooth operation, low noise, and long service life. Its double-shielded design helps retain factory lubrication while preventing the entry of dust and debris, making it suitable for electric motors, industrial pumps, conveyor systems, fans, blowers, machine tools, compressors, and general power transmission equipment.
