Actuators: Repair, Maintenance & Obsolescence

Actuators are vital to keeping automated systems moving. But when they fail, plant operations grind to a halt – costing time, resources, and profitability. Here at AH Group we deliver world-class actuator repair solutions backed by global capabilities, certified expertise, and a group of top-tier suppliers that ultimately provides maximum value for your facility’s maintenance, repair, and MRO strategy.

What is an Actuator?

The definition of an actuator is a mechanical device that converts energy (typically electrical, hydraulic, or pneumatic) into motion. In industrial applications, actuators are responsible for moving or controlling mechanisms, such as valves, dampers, or machine components, with precision and consistency.

There are several types of actuators, including:

• Electric actuators, which use motors to drive movement.
• Hydraulic actuators, which rely on pressurized fluid.
• Pneumatic actuators, powered by compressed air.

Actuators play a critical role in automation across all industries: manufacturing, oil and gas, food processing, utilities, and more. Because they’re constantly in motion, their durability and reliability directly affect production uptime and safety. 

Why Do Actuators Fail?

Actuator failure is a leading cause of unplanned downtime in automated environments. The causes are often preventable with the rightrepair partner and proactive maintenance plan. While it’s never ideal to plan for the worst, it’s imperative that you have a plan in place for when your actuators may malfunction.

Common causes of actuator failure include:

• Contamination: Dirt or debris can infiltrate seals and fluid systems, especially in hydraulic and pneumatic actuators.
• Corrosion: Exposure to moisture or corrosive environments can degrade internal components over time.
• Electrical faults: Wiring issues or circuit board failures can interrupt signals in electric actuators.
• Seal wear and leakage: Repeated use under pressure leads to worn seals, leaks, and reduced performance.
• Improper sizing or misalignment: An actuator not suited for its load or application can degrade prematurely.

Without expert intervention, many of these issues result in full component replacement-an approach that is costly, wasteful, and often unnecessary.

Actuator Repair: Why Choose AH Group?

AH Group is the global leader in MRO repair, helping facilities and organizations reclaim the full value of their industrial components – including actuators – through precision repair, warranty recovery, and more. 

Our approach includes:

• Comprehensive diagnostics: Our engineers and supply chain specialists conduct detailed root cause analyses to understand the reason behind each failure.
• Certified repair process: We restore actuators to OEM specifications-or better-using approved parts and rigorous testing protocols.
• Vendor neutrality: Unlike OEM-only solutions, our vendor-agnostic model taps into a global network of over 3,000 repair sources to drive down costs and turnaround times.
• Data. Intelligence. Results. Through advanced tracking systems and analytics, we give clients the intelligence to make better repair-vs-replace decisions and build smarter MRO strategies.

Whether your actuators are hydraulic, electric, or pneumatic, AH Group helps extend component life, reduce downtime, and reduce environmental waste.

Choose Repair Over Replacement

In today’s industrial landscape, replacement isn’t always the smartest choice. With increasing pressure on supply chains and sustainability goals, repair is both a financially and environmentally sound strategy. This is especially true if your specific actuator may be faced with obsolescence – making repair that much more crucial. 

Actuator repair through AH Group:

• Saves up to 50–70% compared to replacement.
• Keeps components out of landfills, supporting ESG initiatives.
• Minimizes downtime with shorter lead times and global sourcing.
• Provides full visibility into failure trends and repair history.
