The LP+/LPB+ value line of gearheads from alpha gear Inc. offer efficiency with low torsional backlash for less demanding applications. According to the company's press release, the gearheads are maintenance-free for their entire service life due to a unique lubrication concept. 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. The company says the gear reducers achieve a 95% efficiency at full load. The two-stage reducer restricts torsional backlash to 10 arc-minutes while the single-stage version operates at less than eight arc minutes.
