Transmission efficiency range at 1-stage ≥ 94 %, 2-stage ≥ 90 % with life time 20,000 hours. Mounting brackets are ready to any servo motor, or customized by demand.

PUL Series

High Radial LoadThe PUL series of output shaft inline helical gearbox provide a wide range of performance levels to high positioning accuracy and motion control applications, particularly when high radial loading is required. The performance of this precision planetary gearbox is reinforced based on the PUA series. The maximum radial force is increased by an average of 155%. Frame sizes 60-220 mm with the best level of backlash < 1 arcmin. Taper roller bearings with maximum radial load capacity up to 27800N (PUL-220), and axial load capacity up to 16200N. The PUL is specially well suited to work with pinion and rack for linear operation. Commonly adapted in metal cutting machines, wood processing equipment, machine centers and highly dynamic motion control systems. Right angle configuration (PUR) is also available with max. frame size 220 mm.
