High Thrust Electric Cylinders convert servo-motor rotation into powerful linear force using a planetary roller screw or heavy-duty ball screw inside a sealed housing. They replace hydraulic cylinders for press-fitting, stamping, and clamping tasks, offering programmable force control, position feedback, and clean, fluid-free operation with high thrust density in a compact footprint.

High Thrust Electric Cylinders Complete Factory Acceptance Testing

TallMan Robotics has completed factory acceptance testing on a new high-thrust electric cylinder built for heavy press automation. This article covers the testing process, functional performance, and deployment readiness of this electric cylinder actuator from a technical perspective.

Project Overview of these High Thrust Electric Cylinders

The engineering team designed this high force electric actuator around a planetary roller screw core for maximum thrust density. Consequently, the unit reached its target output while keeping the housing diameter compact for tight machine layouts. The testing phase followed a structured qualification plan before the cylinder moved toward production release. This approach confirms the unit performs reliably before it reaches a customer floor.

Functional Highlights of the High-Thrust Electric Cylinder

A servo electric cylinder of this class pairs a high-torque servo motor with a planetary gearbox for torque multiplication. The gearbox then drives a roller screw electric cylinder core, unlike a standard ball screw electric cylinder of equal size. This screw type carries higher load density in the same housing footprint. Meanwhile, integrated guide bushings keep the output rod aligned under off-axis load. An optional load cell also reports real-time force feedback during operation. As a result, this heavy-duty electric cylinder suits tasks that need high thrust and precise force control together.

Testing and Validation Process

Technicians first mounted the cylinder on a dedicated test rig built for repeated cycling under full load. Next, the team ran a staged thrust profile that ramped output from light load to rated capacity. Throughout each stage, engineers logged rod position, force output, and motor current to confirm consistent behavior. The unit also completed an extended endurance run to verify screw wear stayed within the design limit. Finally, the team checked positioning repeatability across the full stroke using a calibrated displacement sensor. This linear thrust actuator held its target accuracy through every stage of testing.

Application Readiness of these High Thrust Electric Cylinders

An electromechanical actuator built for this thrust class fits press-fitting and stamping tasks. It also suits heavy clamping work across automotive and metal forming lines. For example, a stamping cell can use this cylinder during a forming stroke. The design applies controlled force without hydraulic fluid on the shop floor. Similarly, a press-fitting station benefits from programmable force limits that protect delicate mating parts. Consequently, this high-capacity linear actuator gives integrators a cleaner alternative to hydraulic cylinders for high-force tasks.

Test Results Summary

The cylinder completed the qualification program with rated thrust of 30kN. It also held a repeatability of plus or minus 0.02mm across 12,000 continuous cycles. Screw wear stayed within the design tolerance through the full endurance run, and thermal performance remained stable under continuous duty. This case follows ISO 230-2 positioning test methods. It confirms the high-thrust electric cylinder meets its target specification ahead of shipment.
