STR 080E Frame

This versatile solution features programmable output motions with low-wear rolling contact. Larger inertia load transmission is achieved with internal cam ratio reduction while maintaining powerful torque with less motor horsepower. The STR’s unique no-backlash preloaded mechanism improves the overall dynamics to force output motions to a new level of rigidity and accurate servo controller performance. The compact design reduces footprint while offering high speed rotation with large bending moment capacity.
