Deep groove ball bearing

Single-row deep-groove ball bearings are highly versatile, with low friction, optimized to reduce noise and vibration, allowing for higher rotating speeds. They can withstand radial loads and bidirectional axial loads, are easy to install, and require much less maintenance than many other bearing types.
