5.2.1 Brake Centering
The brake can be centered on the mounting surface to an external frame via the outer
diameter of the magnet (OD centering) or to a bearing centered on the shaft via the inner
diameter of the magnet (ID centering). The magnet includes a retaining ring groove for ID
centering. See the KEB Catalog for dimensions for bearings and frames.

5.3 Air Gap Settings
All COMBINORM brakes feature an air gap between the magnet and armature. This is
required for proper functioning of the brake. Shaft-mounted brakes include a pre-
configured air gap but flange-mounted brakes require the air gap to be set during
installation. The correct air gap width X for each size of brake is listed below. Reference
this table when installing any flange-mounted COMBINORM brake.
