684-2Z , 684-2RS Single Row Deep Groove Ball Bearing
Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
Single-row deep groove ball bearings are also subdivided into other types, ranging from 3 mm to 400 mm bore sizes, suitable for almost any application.
