HDA Component Sets

HDA Heavy Duty Pancake Type (with hubs)

The HDA is a heavy-duty pancake design that has the same capacities as the HDR, utilizing a double bearing wave generator and wider splines; it also includes an extended wave generator hub for mounting bearings. The wave generator features a large through bore as well. The HDA is commonly used in differential applications where shock loads are present, such as corrugated machinery and printing presses cutters. The HDA offers low backlash and standard ratios from 80:1 to 200:1 with torque capacities up to 2000 Nm. Custom drives are available upon request.
