Nidec Graessner Planetary Gearbox for Power and Precision

Nidec Graessner PowerGearHS – The HighSpeed bevel gearbox

VRT Robot Flange Range

The VRT series sets the new standard in applications requiring extremely high torque density and rigidity.

Its compact design and robotic industry ISO flange is ideal for equipment requiring high speed, high precision indexing movement and streamlined installation.

The remarkable torsional stiffness and ultra-low backlash combine to provide outstanding positioning accuracy. This product comes standard with <3 arc-min backlash, but is also available with reduced options down to <1 arc-min.

The VRT is the most robust planetary solution in the marketplace and is used across a numerous range of applications, including 7th axis robot shuttles, dial tables, end of arm tooling and any other axis where installation space, reduced assembly time and torque density play an important role.
