Product Description:

The AA3123-42H0-0000 is an electric cylinder produced by Beckhoff within the A Electric Cylinders series. As a linear actuator, it translates rotary servo motion into precise thrust for pick-and-place modules, format adjustments, and other positioning duties on automated machinery. The integrated anti-twist guide keeps the rod from rotating under load, which helps attached tooling stay aligned during extension and retraction. Its OCT multi-turn encoder supplies absolute position data to Beckhoff or third-party motion controllers for closed-loop operation, so the axis can resume accurate movement without a separate external measuring device.

During continuous operation, the cylinder draws 8.1 A and delivers a sustained thrust of 650 N. Its nominal mechanical output is rated at 0.3 kW. A supply of up to 48 V DC energizes the internal drive coils, allowing direct connection to low-voltage motion modules. Acceleration capability reaches 20 m/s², so short strokes can be executed quickly when cycle times are critical. The spindle lead is 10 mm, which balances force output with linear travel speed, and the cylinder reaches a top velocity of 0.56 m/s under suitable operating conditions. Total travel is limited to 150 mm, making the unit suitable for compact assembly stations, transfer devices, and end-of-arm tooling where installation space is restricted.

For brief dynamic events, the winding current may surge to 32 A, producing a peak thrust of 2650 N to overcome breakaway forces or support firm seating movements. Once positioned, repeatability is aided by a positioning clearance of ±0.015 mm, which helps maintain consistent stop points in repetitive motion sequences. Combined static and dynamic load ratings of 19 kN and 9 kN indicate the allowable axial stresses that the housing, spindle, and bearing set can withstand throughout service life. These load limits are important when the actuator is exposed to pressing forces, payload inertia, or frequent reversing motion.
