Nabtesco RD-C Series Gearbox

The RD-C provides a large center thru-hole with a main support bearing together in one complete gearhead. The large thru-hole (up to 5.78 inches) can accommodate cables, shafts, lasers, and etc. for the most efficient design possible with the off-center input providing larger ratio options which 1) reduce the need for a planetary pre-stage reducer and 2) allow for a greater design flexibility in the various output speeds the application requires. The main internal angular support bearings also provide large moment capacities and negate the need for external support devices – reducing design time and installation costs.
