A positioning device (index) is an indispensable item as a key component of automated equipment. It is used in various equipment as a power source for machines, such as "rotate and stop" a table and "repeatedly perform back-and-forth, left-right reciprocating movements". In this article, we will explain why we particularly recommend cam-type index
Cam technology that realizes repetitive positioning with high-precision
For example, it is highly effective for FA equipment under the following conditions
・ High-precision, fast repetitive motion (requires high-accuracy for repetitive positioning)
・ High inertia (load) is applied to the motion
・ Durability required
Ueno (Thailand) has been handling cam-type indexes of Sankyo in Thailand for over 20 years. We compared the following two types of positioning devices with other similar mechanisms.
Roller gear cam (cam type index)
Main features
・ High rigidity with no backlash during stop (tough)
・ High-speed operation is possible and positioning is accurate (fast, repetitive positioning with high-precision)
・ Excellent durability (long-lasting)

▲ Mechanism image
Roller drive (cam type positioning unit)
Main features
・ Unique preload mechanism allows positioning at any angle with no backlash during rotation / stop
・ A high-speed operation is possible and positioning is accurate (fast, repetitive positioning with high-precision)
・ Excellent rigidity and durability (tough)
▲ Characteristics comparison diagram of "Roller drive", "Worm gear" and "DD motor"
▲ Usage example
Sankyo's cam-type index and positioning unit, which is indispensable for high-precision, long-life automation equipment
In the unlikely event that something goes wrong or is damaged, the equipment cannot be remade, so durability and safety are extremely important. Many of our customers have replaced indexes made by Sankyo, which are highly durable, with indexes made by a reasonably priced overseas manufacturer that failed within a short period of time.
✓ High-precision (accurate positioning as per the catalog)
✓ Long service life (almost no defects in the history of sales at Ueno (Thailand))
✓ Highly safe design
We are confident in our recommending these indexes because we ask our customers what kind of equipment they intend to use and guide them to the optimum indexes with a high safety factor calculated prior to sales.
In addition, we have been handling Sankyo's cam-type indexes in Thailand for many years, and our Japanese as well as Thai staff have extensive expertise and experience in these products. It would not be an exaggeration to say that we are the most knowledgeable and experienced trading company in Thailand in handling indexes. In this respect, we have a system in place that allows both Japanese and Thai staff to respond flexibly to customer inquiries.
