Every ZHR actuator undergoes rigorous factory testing before shipment. Documented procedures, calibrated equipment, and traceable results for every serial number.
Our factory is equipped with calibrated test rigs for comprehensive actuator validation. All equipment is traceable to national metrology standards.

Knowing exact backlash, efficiency, and thermal performance lets you model your robot's dynamics accurately—no surprises during commissioning.
Every serial number is traceable to its individual test report. If an issue arises in the field, we can追溯 the factory data to diagnose root cause.
Incoming inspection teams can rely on our documented test data rather than re-testing every unit—saving time and cost in your production workflow.
Request individual test reports, custom test procedures, or witness testing at our factory for your critical applications.
