Single-row deep groove ball bearings with seals or shields on one or both sides are particularly versatile, offering low friction and optimized performance for low noise, low vibration, and high rotational speeds. They can accommodate both radial and axial loads in both directions, making them suitable for a wide range of applications. These bearings are easy to mount and require less maintenance than many other types. The integral sealing system significantly prolongs bearing service life by keeping lubricant within the bearing and keeping out dust.

With flanges bearings, it is easier to fix them to the bearing holes. If you use bearings without flanges, installed into the bearing hole, but also need to be fixed left and right so as not to slip out of the bearing hole; and edge bearing, because one side of the edge, do not need to worry about sliding out of the problem, if you install the wheels, the wheels themselves play a role in jamming left and right, left and right do not need to worry about sliding out of the problem.
