altThe LP+/LPB+ Value Line series of gear-heads from alpha gear drives (Bartlett, IL) offer a lubrication concept that makes them maintenance-free. The LPB+ offers the option of adding an integrated geared pulley drive system. The belt pulley eliminates the need for a right-angle gearbox, couplings, and/or additional bearings. At full load, the gear reducers achieve more than 95% efficiency; the two-stage reducer restricts torsional backlash to less that 10 arcminutes, while the single-stage version operates at under 8 arcminutes.
