PUR Series

High Radial Load Capacity

The PUR series of output shaft right angle helical gearbox provide a wide range of performance levels to high positioning accuracy and motion control applications, particularly when high precision and high torsional rigidity are required. Frame sizes 60-220 mm with the best level of backlash ≦ 2 arcmin. Taper roller bearings with maximum radial load capacity up to 27800 N, and axial load capacity up to 16200 N. The PUR 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. Inline configuration (PUL series) is also available with max. frame size 220 mm.
