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.

High precision:standard backlash is 3arc-min, ideal for higher levels of positional accuracy
High rigidity and torque: rigidity and torque capacity are achieved by using uncaged needle roller bearings
High load capacity: tapered roller bearings were added to the output section to increase radial and axial load ratings on most frame sizes
Adapter-bushing connection: enables a simple, effective attachment to most servo motors
No leakage through the seal; high viscosity, anti-separation grease does not liquefy and does not migrate away from the gears
Maintenance-free: no need to replace the grease for the life of the unit. The reducer can be positioned in any orientation
