HLD60 with Twin External Rail Harmonic Actuator is available in a standard commercial grade and a high precision grade. The HLD is comparable to a ball screw actuator in accuracy, but the HLD is available with zero backlash inherent gear reduction built in. Unlike conventional ball screw actuators, the HLD accuracy extends to travel lengths from 100mm to 3.3 meters as a standard product. The cost however, is far lower than commercial grade ball screws for travel in excess of 600 mm.
The HLD is commonly used instead of regular belt slides because it is a low cost system due to the elimination of expensive gear reduction. The HLD reduction is built in. The HLD includes the Animatics SmartMotor™ model SM2315DT as standard. Other Animatics SmartMotors in NEMA frame sizes 17 and 23 are available.
