Harmonic linear drive needs no brake

The harmonic linear drive (HLD) is a linear-belt-drive solution providing high accuracy and low cost without the need for a gearhead or brake. The HLD uses a recirculating belt, folded back upon itself and routed over different diameter pulleys yielding gear reduction by way of the harmonic drive principle, without the cost or backlash of a separate gearhead. The system has a low price-to-performance ratio. It is available in standard stroke lengths from 100 to 3200 mm and equivalent pitch ratios from 2.5 to 12.5 mm/rev.
