Airtangent 2002 Linear-Tracking
Air-Bearing Tonearm

The massive main housing is actually in two parts. One half is stationary and bolted to the armboard. The other is free to move vertically and acts as a central coupling point for all the components comprising the tonearm. A miniature rack-and-pinion gear assembly is provided to move the two pieces with respect to each other. The two pieces are accurately linked by a vertically aligned linear ball bearing, and can be moved with respect to each other with the help of the rack-and-pinion providing a fine-pitched, rock-solid, smooth and continuous VTA adjustment system.
