Single Row Deep Groove Ball Bearings With Filling Slots 306

Single Row Deep Groove Ball Bearings With Filling Slots 306

The 306 is a single-row deep groove ball bearing with a 30mm bore and 72mm outer diameter, crafted from sturdy chrome steel. It manages radial loads up to 6677 lbf and can spin at speeds reaching 11000 RPM.

Its open design with filling slots allows for easy lubrication, while the nylon cage reduces friction for smoother operation. The bearing performs reliably in temperatures ranging from -30°C to 120°C.

This model is interchangeable with SKF bearings, offering a practical replacement option. It’s well-suited for applications like electric motors or pumps where radial loads are common.

Weighing 0.37kg, it’s a balanced choice for its size, meeting RoHS and REACH standards for safety and environmental compliance.
