Technical information on deep groove ball bearings

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)
  • high demands are made on the sealing of the bearing, without increasing heat generation or limiting the speed (Generation C)
  • 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
  • axial loads in both directions and/or tilting moments must be supported in addition to radial loads
  • a high load carrying capacity is required and the design envelope available in a radial and axial direction is relatively small

Comparison of standard deep groove bearings with bearings of Generation C: running noise, frictional torque

C = bearings of Generation C

MR = frictional torque

nG = limiting speed
