Single-row ball bearings
Description
The geometry of the four point contact ball bearing track is that of a gothic arch where the track of each ring has two equal radii of curvature with different centres. Under axial, radial and moment-based loads, rolling elements experience different contact angles and the distribution depends on the external load and structural rigidness. As the diameter of the ball increases, the double row ball option increases in competitiveness. Both dynamic and static capacity are significantly improved as the contact angle increases. Single row ball bearings are used in applications such as construction machinery, blade and yaw bearings in wind turbines, water treatment, etc.Technical data sheet

Double-row ball bearings
Description
A 2-row ball bearing with 4 contact points (also called 8 contact point bearing) becomes the best option compared to a single row ball bearing as the required diameter of the ball increases to support higher loads. An angular tilting at torque load is lower with double-row balls than with 1. This technology is mainly used for blade bearings in wind turbines, but also in large construction cranes.Technical data sheet
