Improved comfort for all types of comfort armchairs: The MICRODRIVE 3 single drive features a very compact design in a full-metal housing. The very small installation size of 105 millimetres plus the stroke (of +- 2 millimetres) provides manufacturers with great freedom during the design of their products. The gear clevis, which can be rotated 90 degrees and has a bore of 8/10 millimetres and a 5-millimetre slot, allows for very variable installation options.

The MICRODRIVE 3 adjusting drive – with its compressive force of 4,000 Newtons and a stroke length of max. 350 millimetres (+- 2 millimetres) – is ideally suited for a wide range of seating applications. Outstanding mechanical stability is ensured by the metallic grey full-metal housing enclosing the single drive, the stroke pipe made of aluminium and steel, and the aluminium guide profile. Reliable operations are ensured at all times, thanks to the maintenance-free DC motors in the adjusting drive.

The MICRODRIVE 3 also enables a fast adjustment speed of 35 millimetres per second. This permits seating furniture (such as comfort chairs) to be moved to their desired positions as quickly as possible. The adjusting drive is optionally available with a Hall sensor.
