Self Aligning Ball Bearings 1220 K

Self Aligning Ball Bearings 1220 K

The 1220 K is a self-aligning ball bearing with a 100mm bore and 180mm outer diameter, crafted from sturdy chrome steel. Its double-row design helps manage radial loads up to 15502 lbf, with a maximum speed of 4800 RPM.

The open seal type allows for easy lubrication, while the nylon cage reduces friction for smoother operation. It performs reliably in temperatures ranging from -30°C to 110°C.

This bearing is interchangeable with SKF models, offering a practical replacement option. Suitable for machinery where misalignment or heavy radial loads are expected, such as conveyor systems.

Weighing 3.6kg, it’s a robust yet manageable size. Compliant with RoHS and REACH standards for environmental safety.
