CONSIDERATIONS WHEN EVALUATING HEAVY DUTY LINEAR ACTUATORS

For industrial and mobile applications, the performance of a system heavily depends on selecting the appropriate heavy-duty linear actuator. These actuators must be capable of withstanding tough operating conditions, generating substantial force, and offering reliable operation with low maintenance requirements. When evaluating technologies, many manufacturers specifically look for a low-maintenance actuator for continuous duty cycles to keep production running efficiently. We break down the top challenges and key factors to consider when making your selection.

TRADITIONAL ACTUATION TECHNOLOGIES: LIMITATIONS & ALTERNATIVES

Hydraulic Actuators

✅ Provide high force and durability

❌ Prone to leaks, high maintenance, and complex system integration

Electro-Mechanical Actuators (EMAs)

✅ Offer precision control

❌ Costly at high force levels and susceptible to damage from shock loads and metal-to-metal wear

KYNTRONICS’ HYBRID LINEAR ACTUATORS: A RELIABLE ALTERNATIVE

Kyntronics’ Hybrid Linear Actuators (SHA) combine hydraulic power with the precision of electric servo control, eliminating the drawbacks of traditional hydraulic and electro-mechanical systems.

Advantages of SHA Technology:

✅ Unmatched Robustness: Withstands shock loads and side forces without failure

✅ Low Maintenance: Fully sealed design prevents leaks and reduces upkeep—ideal for anyone needing a low maintenance actuator for continuous duty cycles

✅ Precision Control: Closed-loop servo control for exact position, speed, and force regulation

✅ Custom Configurations: Available in force ratings up to 150,000 lbs. and stroke lengths up to 120 inches

PROPER-ACTUATOR SIZING & SAFETY CONSIDERATIONS

Kyntronics engineers collaborate with customers to ensure optimal actuator sizing based on required force, speed, duty cycle, thermal management, and control integration. SHA systems include built-in safety features such as:

• Relief valves for overload protection
• Thermal sensors to monitor and prevent overheating
