1309 K CMB self aligning ball bearing 45x100x25

Industrial applications

The 1309 K CMB self aligning ball bearing is designed for applications where shaft misalignment or deflection occurs during operation. It is widely used in conveyors, fans, agricultural machinery, and industrial drive systems.

Thanks to its 45x100x25 mm dimensions, this bearing is suitable for medium-duty mechanical systems requiring flexibility and reliability under varying operating conditions.

Construction and design

1309 K CMB is a double row self aligning ball bearing featuring a spherical outer raceway, allowing automatic alignment between the shaft and housing. This design compensates for angular misalignment and reduces stress on the bearing.

The tapered bore (K) enables mounting on adapter sleeves or tapered shafts, providing flexibility in installation. The CMB version indicates a matched bearing set, ensuring precise fit and stable operation.
