ST Series Rotary Index Tables from Nidec Shimpo

Nidec Shimpo ST Series Rotary Index Tables
The STH is an excellent fit for mid-range index table applications that require high accuracy, flexible mounting and a large hollow shaft. This product sets the standard for rotary positioning performance of large inertia loads at an exceptional value. The STH comes with backlash as low as 2 arc-min and indexing accuracy down to +- 60 arc-sec. With a large cross roller bearing, the STH can achieve a max tilting moment load capacity of 200Nm and a maximum radial load of 5000N—a perfect match for mid-size steel or aluminum tables as well as end of arm tooling.

The STR series is Nidec Shimpo's ultra-high precision solution that 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.
