These compact, light-weight, minimal backlash inline gear reducers have been at first created for encoder programs. They are also ideal for a lot of other generate methods. Encoder gear reducers have a really low second of inertia at the shaft input and are rated for enter speeds up to 3000 rpm. Two frame dimensions are accessible with equipment ratios from 4.96:1 to 3600:1. Our encoder gearbox sync pads are accessible from inventory.
