Product description
The Self-Aligning Unit (SAU) EZ-8046 is a spherical air bearing that enables friction-free alignment for mounting, assembly, or pressing operations. It allows self-alignment in the joning plane (± 1° tilt) and provides precise and repeatable alignment in any angular position. The pressing operation must be performed at the working point to ensure parallelism better than 2 µm. To lock the set position, simply switch off the air supply. The mover (upper part of the bearing) remains magnetically fixed until the SAU is reactivated with air. Installation is possible in both upright and suspended orientations.

Alignment procedure
Step 1
Air Supply Activated
The tool moves down-ward. Pressure is transmitted from the workpiece holder to the mover (up-per part of the SAU). The air supply is active.
Step 2
Air Supply Activated
The alignment is carried out as the mover adjusts to the target position. The air supply remains active. The workpiece is aligned within a maximum tilt angle of ±1°.
Step 3
Magnetic Preload
Once the alignment is complete, the air supply is switched off. The mover is secured to the base by magnetic preload forces, holding it firmly in the aligned position.
Step 4
Magnetic Preload
The tool retracts. The workpiece remains securely fixed in the aligned position and is held for further processing until the air supply is reactivated.
