Application

Brief introduction

The ELITE HFT2S two-speed gearboxes are mainly used in machine tool main spindle drives, test benches, and applications requiring high torque.

For example, the gearbox can be used in turning machines (horizontal B3/B5) and machining centers (vertical V1/V3) due to its variable installation positions (see page 10). It is also suitable for many systems where torque increase and/or speed reduction is required.
