SKF angular contact ball bearings introduce free combination pairing

Arbitrary matching bearings are specially manufactured so that when they are arranged and mounted together a certain internal clearance or preload and/or uniform load distribution can be obtained without the use of gaskets or similar devices. Any pair of bearings has a type suffix to indicate internal clearance (CA, CB, CC) or preload (GA, GB, GC).

When ordering, specify the number of individual bearings required, not the number of bearing sets. When the bearing capacity of a single row of bearings is not enough, it is installed in pairs (tandem configuration); Or when the load is a composite load or an axial load acts in two directions, pairing is used (back-to-back and face to face pairing). When the load lines are configured in series, the radial and axial loads are evenly shared by the bearings. However, the bearing assembly can only withstand axial loads acting in one direction. If the axial load acts in the opposite direction, or if there is a compound load, a third bearing adjusted relative to the series-paired bearing must be added.

The load lines of the back-to-back paired bearings are separated onto the bearing shaft. It can withstand axial loads in two directions, but the load in each direction can only be borne by one bearing. The back-to-back mounted bearings provide a relatively rigid bearing configuration that can withstand the flip moment. The load line facing the paired bearing converges towards the bearing shaft. It can withstand axial loads in two directions, but the load in each direction can only be borne by one bearing. This configuration is not as rigid as back-to-back pairing and is not suited to withstand a flip moment. Universal matching bearings also have advantages when used in combination with a single bearing. Most bearings are SKF Explorer series, so they have higher accuracy, load capacity and higher speed.
