GCL Cycloidal with Pre-Stage for Easy Integration

Do you need a cycloidal gearbox with additional reduction or a right angle input?

GAM provides a complete gearbox, including the integrated pre-stage, ready to mount into your application. A single produt with a single part number simplifies ordering.

Pre-Stage options include:

  • Right angle turn with additional speed reduction using hypoid gearing for a compact configuration
  • Right angle turn in low ratios from 5:1 down to 1:1
  • Inline configuration with additional speed reduction

As with all GAM gearboxes, the GCL cycloidal with pre-stage comes with a motor adapter plate ready to mount your motor



The GCL cycloidal is well suited to high-end industrial robotics and motion control applications with its ability to withstand start-stop impact loads five times nominal torque.
