Single ball row bearings

Bearings ball radial-stop with four-dot contact - perceive thrust loads in both directions or the combined radial load at simultaneous action axial.

Ball bearings with the four-point contact represent single radial-stop ball row bearings, with the swing paths expected perception of the thrust loads operating in both directions. The perceived radial loads can make only part of thrust load. Bearings of this type occupy much less the place in axial spaces, than double-row bearings.
