The Arm series page gathers the arm-type heart of the Yamaha Cartesian catalogue: PXYx for economy two-axis work at 4.5 kg, FXYx and FXYBx for mid-range strokes, SXYx and SXYBx for three- and four-axis cells up to 3050 mm of X travel, and MXYx where the moving arm must carry 30 kg. Gantry, moving-arm and pole variations extend the same axis platform into different cell layouts.

What stays constant across the ladder?

The motion discipline: 1200 mm/s maximum speeds on the moving-arm types, orthogonal slide-axis construction from two to six actuators, and strokes ordered in catalogue steps rather than custom weldments - with special orders accepted for strokes and payloads beyond the standard line. A plant can start at PXYx economy tier and climb through SXYx into MXYx without changing the programming culture.

Where do the NXY and HXY types fit?

The NXY hollow-servo long-stroke family and the HXYx and HXYLx heavy frames up to 40 kg and 50 kg sit beside the Arm series as the dedicated long-distance and high-load tiers - the NXY even takes double-arm configurations. For buyers, the Yamaha argument is one catalogue covering everything from postcard-sized pick-and-place to line-length transfer, with controllers and spares shared across the whole Cartesian range.
