4-Axis Cartesian Robots Guide

A 3-axis robot moves along X, Y, and Z linear axes only, suitable for straightforward part extraction. A 4-axis robot adds a rotational wrist (servo wrist unit), enabling part reorientation after extraction. This fourth axis allows downstream placement, part flipping, and integration with conveyors or assembly stations without additional handling equipment.

Cartesian robot pricing varies widely based on payload capacity, stroke length, axes configuration, and controller features. Entry-level sprue pickers start lower, while high-end traverse take-out robots for large-tonnage IMMs command premium pricing. Yushin America provides all pricing on request — contact the team via the quote form for configuration-specific pricing tailored to your application.

Yushin's Cartesian robot lineup spans payloads from under 2 kg for sprue/runner pickers, 2–15 kg for light-duty take-out, 15–50 kg for medium-duty applications, up to 65 kg for LA Series large-part robots, and 80+ kg for the MKA-2000S ultra-heavy-duty configuration. Choose the model matched to your part weight and IMM tonnage.

Yushin's Cartesian robots cover the full IMM tonnage spectrum: sprue pickers suit 30–300 ton machines, mid-range take-out robots handle 150–650 ton IMMs, FRA Series covers ~400–1,500 ton cells, LA Series targets 600–1,500 ton machines, and the MKA-2000S serves ultra-large 800–3,000 ton injection molding machines.

Yes. The SX-41 High-Speed Side-Entry Robot is specifically designed for ISO Class 6 clean room compliance per ISO 14644-1, featuring sealed bearings, FDA-grade lubricants, and minimal-particulate motion profiles. It is configurable to ISO Class 7/8 environments and is widely used in medical disposables, pharmaceutical packaging, and optical component molding.

Yushin Cartesian robots integrate seamlessly with downstream gate-cutters, sprue cutters, vision inspection stations, conveyor systems, and the PA Series compact palletizing robot. The PA Series supports up to 420 boxes/hour and pairs directly with take-out robots for full lights-out part-to-pallet automation. EtherCAT, EtherNet/IP, and DeviceNet protocols ensure broad compatibility.
