Deep groove ball bearing

characteristics of deep groove ball bearings

The best known type of rolling bearing, is the deep groove ball bearing, it is designed to absorb mainly radial forces. This bearing can also support small axial forces. The axial load capacity is approximately 10% to 20% of the radial load capacity.

Deep groove ball bearings are available in single row and double row as well as open and sealed. For manufacturing reasons, open bearings can have recesses on the outer ring for sealing or cover washers.

The higher the radial deep groove ball bearing is loaded at increasing speeds, the more the service life is reduced with a simultaneous increase in friction and bearing operating temperature. About the values for the load capacity of the bearing, our service team will be happy to provide information.

The full complement design of radial deep groove ball bearings represents a special design, which due to the higher number of rolling elements offers a higher radial load capacity compared to cage guided radial deep groove ball bearings.

Loads

For the minimum radial load of radial deep groove ball bearings, a ratio of Fr/Cr>0.01 is recommended for continuous operation. The values for the dynamic load rating Cr can be found in our product data sheets.

Accuracies

The dimensional and running tolerances of radial deep groove ball bearings normally correspond to the tolerance class P0 according to DIN 620-2.

Bearing Clearance

The deep groove ball bearings are designed in the standard with the bearing clearance class CN according to DIN 620-4.

Sealing

Deep groove ball bearings are usually designed with dust covers or RSR-Sealing discs designed. Depending on the installation space, Sealing systems are also possible.

Cages

Deep groove ball bearings can be supplied with plastic or metal cages to be equipped.

Materials

The deep groove ball bearings are made in your standard version from the material 1.3505 (100Cr6) and manufactured with a minimum hardness of 58 HRC. On request, corrosion protected versions are available.
