ST Series Variants
NIDEC-SHIMPO first developed its STH off-set hollow bore rotary gearbox for a variety of robotic handling applications that were commonly encountered within the semiconductor industry. When eventually released to general industry, this rotary stage gearbox design became extremely popular with many Custom Assembly and Test equipment builders. These OEM customers often wanted to apply the STH to a tooling fixture, end-effector, dial, etc., within their custom equipment. SHIMPO quickly expanded the variety of ratios supported for the series and the configurations available at the input side, in order to provide more flexibility and options for these turn-key projects.
SHIMPO has expanded its indexing product offering with the STR, to handle those applications that require larger overall torque carrying capacity with even finer levels of precision. To this day, we continue to look towards expanding this product category to better satisfy the needs of our loyal Custom Automation and Test OEM customers around the globe.
