The PGR PSH series combines helical and worm gear stages with a 90° angle between input and output shafts. It is aimed in particular at driving and positioning transport platforms.

The series covers 0.2–15 kW, 3–3600 Nm and output speeds of 0.2–330 rpm. The rigid housing, available in foot-mounted and housing-mounted versions, is designed for good heat dissipation. Options include motor-coupled, IEC, PAM, W and servo motor inputs; solid shaft, hollow shaft or shrink disc outputs; and B5 flange, B14 flange and torque arm accessories.

Housings are made of ductile iron (GGG 40-50) or grey cast iron (GG 20-25). Helical gears are forged 21NiCrMo2, worms are 16MnCr5 case-hardening steel and wheels are CuSn12Ni2-C bronze.
