PHS Series Gearboxes

The PHS Series is a robust line of single-stage parallel horizontal gearboxes designed for applications demanding high thermal and mechanical efficiency. It is available in two configurations: a standard version with a monoblock housing and splash lubrication, and a heavy-duty version featuring a split-plane housing with a dedicated pressure lubrication system.

With power ratings up to 12 MW and nominal torques up to 185 kNm, the PHS Series is ideal for high-speed, high-load environments. Designed with precision helical gears in line with standards, it ensures smooth operation, excellent load transmission, and long service life. This series is well-suited for industrial operations requiring reliable, high-capacity power transmission in a compact footprint.
