The Next Generation

With the AMS Series gear drives, we have taken and built on the tried and true E-Gear.  Improving on things like overall size, materials and speed.  The 370:1 provides a 30% increase in speed over the comparable 4000 E-Gear model without sacrificing torque.  We created a one-piece housing to minimize potential for leaks and invested in casting it in die-cast aluminum.  The die-casting process allows for far greater precision tolerances for a better built drive.  The output shaft is coated for protection and the motor attaches using a flexible lovejoy style coupler.  The AMS Series has been in production since 2015 and is quickly becoming our flagship line.
