Right-Angle Planetary Geared Lean Motors

An extremely precise right-angle planetary gear unit for small installation spaces – combined with an encoder, IE5-classified Lean motor.

The PKX gear unit series features impressive high precision, high-quality helical gearing, and strong backlash stability.

Right-angle planetary geared Lean motors: Round the corner with high efficiency.

When combined with a Lean motor, the result is a very compact, cost-effective drive unit – without any offset and ideal for tight installation spaces.
