PHFR Series

PHFR Series

The PHFR Precision Round mounting flange, caged precision class helical planetary speed reducer in a right-angle housing through sizes 255. ISO-9409 flange output, high torque capacity, quiet operaon with backlash as low as <2 arcmin. This gearbox provide a wide range of performance levels to high positioning accuracy and motion control applications, parcularly when high precision and high torsional rigidity are required. Taper roller bearings with bending moment load capacity up to 6500 N.m, and axial load capacity up to 21850 N. The PHFR 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 moon control systems. Inline configuration (PHF series) is also available with max. frame size 255 mm.
