Deep groove ball bearings are available in single row and double row designs.

Single row bearings are particularly suitable where:

• high and very high speeds are required
• the bearing arrangement must be operated with very low friction
• very low running noise is required, without reducing the speed, load carrying capacity and operating life of the bearing (Generation C) ➤ link
• high demands are made on the sealing of the bearing, without increasing heat generation or limiting the speed (Generation C) ➤ section
• the bearing position is to be designed particularly economically

Double row bearings can be considered for bearing arrangements where:

• the load carrying capacity of single row deep groove ball bearings is no longer sufficient ➤ link
• axial loads in both directions and/or tilting moments must be supported in addition to radial loads ➤ link
• a high load carrying capacity is required and the design envelope available in a radial and axial direction is relatively small
