THE IMPORTANCE OF LINEAR ACTUATORS IN AUTOMATED MACHINERY

EXPLORING LINEAR ACTUATOR TYPES

1. Pneumatic Actuators: Pneumatic actuators are well-suited for simple, high-speed tasks like material transfer and pick-and-place robotics. They are cost-effective and easy to implement but lack the precision required for applications demanding precise control. Additionally, they require a continuous compressed air supply, which can increase operational costs.

2. Hydraulic Actuators: Hydraulic actuators are powerful and commonly used in heavy-duty applications such as clamping and pressing. While they provide high force output, they require regular maintenance and can suffer from hydraulic fluid leaks, reducing efficiency and increasing maintenance costs.

3. Electric Actuators (EMAs): Linear electric actuators, often referred to as electro-mechanical actuators (EMAs) are typically found in automated machinery due to their precise and programmable movement. They are electrically powered and utilize mechanical components such as screws, gears and belts to actuate and transmit force. These actuators provide accurate position control, are programmable, energy efficient and offer relative flexibility in stroke length and speed of movement. However, EMAs are highly susceptible to damage from shock loads, and their mechanical components can wear prematurely over time due to metal-to-metal wear. Electric actuators are also relatively expensive, particularly in higher force configurations and require regular lubrication maintenance to prolong their life.

• Leak-proof sealed system reducing maintenance needs.
• Superior shock load resistance compared to EMAs.
• Energy-efficient power-on-demand functionality.
• Extended durability and longevity.
• Smooth operation with precise control.

KEY CONSIDERATIONS WHEN SELECTING A LINEAR ACTUATOR

Choosing the right linear actuator depends on several factors:

• Load Capacity: Can the actuator provide the required force?
• Speed: Does it meet the speed requirements of the application?
• Precision Control: How accurately can it hold position, force and speed.
• Environmental Conditions: Will it reliably operate in the intended environments?
• Maintenance Requirements: How often does it require servicing?
• Energy Efficiency: Does it optimize energy consumption?
• Cost:  Considering one-time costs and ongoing operating costs. Operating costs are often several times higher over the life of the equipment than the upfront cost depending on the actuation technology chosen.

Kyntronics’ Hybrid Linear Actuators address all these factors, providing precision control, minimal maintenance, high durability, and energy efficiency across various industrial applications.
