Low-backlash planetary gearboxes, PG28 to PG62.
Straight and helical series with hardened steel gears and a one-piece planet carrier for high torque density in a small footprint. Standard backlash of 7 arcmin, precision classes down to 3 arcmin.
Series overview
PG28 series
Compact stage for handheld devices, camera gimbals and small laboratory automation. 1–2 stage, ratios 3.6:1 to 36:1.
PG36 series
The workhorse for 3D printers, pumps and valve actuators. 1–3 stage, ratios 3.6:1 to 100:1.
PG42 series
Most-requested frame for AGV wheel drives and robotics joints. Precision class available with hardened helical stage.
PG52 series
Higher-torque stage for packaging, labelling and textile machinery. Reinforced output bearing for radial load.
PG62 series
Heavy-duty stage for CNC, laser cutting and solar tracking slew drives. High-rigidity carrier and oversized bearings.
