Robot Linear Actuators for Robotics Applications

A linear actuator produces straight-line motion by converting rotary motor torque into linear displacement, typically through a timing belt, ball screw, or rack-and-pinion mechanism. In Yushin take-out robots, AC servo motors drive timing-belt linear actuators on each axis, delivering programmable speed, position, and force profiles for repeatable, high-speed part extraction from injection molding machines.

Yushin America offers four speed classifications: Standard (YD/YD2, CT/CT2, HOP Five), High-Speed (HST, SXB, LA Series), Super-High-Speed (HSA, TSXA, SXC family), and High-End Precision (FRA Series, RC-SE). Selection depends on cycle-time targets, part value, and molding machine tonnage. Super-high-speed models achieve verified take-out times as low as 0.27 seconds for thin-wall packaging and IML cells.

Yushin's portfolio spans 20 tf to over 2500 tf. Compact pickers (HOP Five, N-HOP, YD-0310) cover sub-150-ton presses; mid-range robots (YD, HST, HSA, SXB, SXC) serve 50–650-ton machines; large-tonnage robots (FRA, LA Series, MKA-2000S) handle 600–3000-ton IMMs. Contact Yushin America with your press tonnage for a specific model recommendation.

Yes. The SX-41 High-Speed Side-Entry Robot is ISO Class 6 certified (per ISO 14644-1) with sealed bearings, FDA-grade lubricants, and a minimal-particulate motion profile. It is configurable to ISO Class 7/8 environments and is widely used for medical disposables, pharma packaging, optical molding, and electronics micro-molding requiring strict particulate control.

In-mold labeling places a pre-printed label inside the mold cavity before injection so it fuses permanently to the part. IML requires very precise robot positioning and minimal mold-open dwell time. Yushin's HSA, TSXA, SXB, SXC-HSY, HST, RC-SE, and FRA Series all support IML with double-wing EOAT configurations and label-place I/O, making them suitable for thin-wall food containers, dairy tubs, and caps-and-closures programs.

Yushin's ECO Vacuum (Patent Pending on some models) uses intelligent vacuum circuit management to reduce compressed-air consumption by up to 78% on the RC-SE and 75% on the HSA and CT/CT2 Series versus earlier designs. Lower air draw reduces electricity costs for compressors, decreases wear on pneumatic components, and supports sustainability goals — resulting in measurable cost savings over the robot's service life.
