Expertise design based on German National Standards. High efficiency, high strength, and low noise. For ratio from 20:1 to 60:1, three-stage configuration improves the strength of gears and the service factor. Customer's choice of either IEC or NEMA motor flange. The first stage gear shaft (input pinion) is supported by two bearings. Whole gear carbonized. Using gray cast iron (FC20) on housing, flange, and output end cap allows high impact resistance. Come with lubricant to save your cost and time. Mounting and shaft dimensions are comparable with most USA and European models.
