Electric Linear Servo Actuators Explained

Servo-driven robots offer programmable motion profiles, higher repeatability, faster cycle times, and significantly lower energy consumption compared to pneumatic systems. They allow Auto Tuning of ejector delays, support predictive maintenance via torque monitoring, and can be precisely matched to mold opening windows — capabilities pneumatic systems cannot replicate.

Yushin's lineup covers a very wide range. The YD-0310 Servo Picker suits sub-150-ton small presses; the YD/YD2 series handles 50–850 ton; HSA super-high-speed robots target 100–650 ton packaging cells; the RC-SE high-end robot scales from 30 tf to 1,300 tf clamping force. Side-entry SXC/TSXA families span approximately 50–800 ton.

The HSA Super-High-Speed and the side-entry SXC/TSXA series are the primary IML choices. Both support double-wing EOAT for simultaneous label-place and part-extract. The RC-SE is recommended for premium IML cells requiring tight label-registration tolerances. All three offer sub-5-second cycle compatibility and dedicated IML I/O support.

The Smart ECO Vacuum circuit reduces air consumption by up to 78% versus traditional systems. Long Life Mode on the RC-SE reduces power consumption by 5% while extending guide shaft and timing belt service life. The HSA's ECO Vacuum suction circuit cuts air use by 75% compared to prior models, directly reducing compressor load and operating costs.

Yes. The YD/YD2 series is specifically designed as the anchor robot for lights-out cells, pairing with sprue separators, runner grinders, inline vision systems, and downstream conveyors. The E-touch II controller supports USB/Ethernet I/O, recipe memory, and the YC Email Notification Module, enabling fully unattended overnight or weekend production runs.

Payload ranges vary by model: the YD-0310 Servo Picker handles 1–3 kg; the HSA and side-entry robots target 3–8 kg light-duty; the YD/YD2 standard series covers 5–50+ kg; the RC-SE high-end robot supports variants from 5 kg up to 50 kg, making it suitable for heavy automotive or insert-molding applications requiring large EOAT assemblies.
