Hydraulic & Pneumatic Actuator Repair Services
Actuator problems can affect far more than one component. Loss of pressure, inconsistent movement, leaks or weak clamping can interrupt production, reduce repeatability and create safety concerns. NNG Industries provides inspection, repair, rebuilding, exchange and replacement support for hydraulic and pneumatic actuators used in CNC workholding systems and other industrial equipment. The goal is not simply to replace seals and return the unit. NNG evaluates wear, internal damage, pressure loss, leakage and related operating conditions so the recommended service path reflects the condition of the actuator and the requirements of the system.

Technical Support Built Around Reliable Actuation
Actuator problems are not always caused by one failed seal or visible leak. Wear, contamination, pressure loss and internal damage may all affect performance. NNG evaluates the actuator, application and available service options so customers can make a more informed decision about repair, rebuilding, exchange or replacement.

ACTUATOR REPAIR QUESTIONS
What Customers Need to Know
Answers to common questions about actuator repair, rebuilding, pressure testing and what to send with a service request.
What information should I provide?
Send the machine manufacturer and model, actuator manufacturer and model, serial number, pressure type, symptoms, photos and required timing.
What actuator problems can NNG evaluate?
NNG may evaluate leaks, pressure loss, inconsistent movement, weak clamping, slow operation, internal wear and visible component damage.
Can NNG repair both hydraulic and pneumatic actuators?
NNG may support both hydraulic and pneumatic actuator systems, depending on the manufacturer, model, condition and parts availability.
What testing is performed after repair?
Testing may include leak testing, pressure testing, actuation testing, dimensional verification and functional operation appropriate to the completed work.
Are exchange actuators available?
Exchange availability depends on the manufacturer, model, configuration and current inventory.
Can NNG support obsolete actuators?
Support may be possible when repairable components, technical information, seals or suitable replacement options remain available.
Need Hydraulic or Pneumatic Actuator Service?
Send the machine information, actuator details, pressure type, symptoms, photos and required timing. NNG will review the information and help identify the most practical repair, exchange or replacement path.
