The PHF series of flange type 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 42-255 mm with the best level of backlash ≦ 1 arcmin. Taper roller bearings with bending moment load capacity up to 6080 N.m, and axial load capacity up to 21850 N. The PHF 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 is also available with max. frame size 255 mm.
