A distance plate is required if you want to attach incremental measuring heads directly to the bearing outer ring. M4 threads are already present in the bearing outer ring at a distance of 51mm. These are suitable for absolute measuring heads as well as for adapting a distance plate, which can be used for incremental measuring heads via the M3 thread at a distance of 16mm. In order for an incremental measuring head to be able to measure at the correct position, the two distances DP-L and DP-H must be adapted using such a distance plate, for example.<\/p>\n<\/div>
