These bearings are used in low-power electric motors, centrifugal fans, centrifugal pumps, small compressors and light transmission equipment. In Argentine industry they appear in packaging lines, machine tools, air conditioning equipment and internal transport. Their sealed or open construction allows them to be adapted to dusty or humid environments, depending on the required protection.

To select the bearing, consider the radial and axial load, the rotation speed and the working environment. If there is dust or liquids, choose a variant with seals or shield plates. Mounting must be done with suitable tools, without striking the rings, and verifying the alignment of the shaft and the housing. Correct lubrication and precise fitting extend the bearing's service life.

Deep groove ball bearings are interchangeable between brands if the main dimensions and the type of protection match.
