How to convert high-force linear actuators from hydraulic to electric

Part 2 of 2

Things are changing in industrial automation. Many linear motion applications are getting more sophisticated with increased demand for control of process variables like velocity, thrust, acceleration/ deceleration and more.

It’s common for new applications that require high thrust from a linear actuator to use electric motion systems. Moreover, machine designers are converting existing hydraulic motion systems to electric.

High force linear actuators: how to convert from hydraulic to electric

Part 1 of 2

Electric linear actuators have come a long way – especially in the area of high force.  Once upon a time when an application required high force, the usual linear motion solution was a hydraulic cylinder. However, as industrial automation gets more sophisticated and the need for precise control of speed, force and other variables grows, more engineers are considering electric high force linear actuators.

Integrated servo motor and controller ensures actuator precision, versatility

Powder-filling applications require precision and versatility.  Precision to fill containers to the exact weight or volume.  Versatility to accommodate changes.

Machine designers depend on electric linear actuators to deliver precision and versatility. And they’re finding that an integrated servo motor and controller coupled with a reliable electric actuator can do just that.

Hush! Minimizing noise in electric linear motion systems

Under most circumstances electric linear motion systems are quiet.  They certainly don’t create the hissing and bang-bang noises associated with pneumatic systems. However, there’s another type of noise that comes with electric systems of all types – electrical noise or interference.

This is a common occurrence caused by random fluctuations in electrical signals. If the amplitude gets high enough, electrical noise can disrupt the operation of devices like electric linear actuators.  The results can be anything from erratic movements to complete system failure.

Electric high speed linear actuator reduces conveyor’s TCO

Higher production speeds usually translate into higher output volumes – a good thing in manufacturing. At least it’s good if product quality stays high and operating costs remain in line.  Machine designers are on the look-out for high speed linear actuators and other devices that can streamline processes.  But those high-speed solutions need to be reasonably priced and efficient to use.

Electric rod actuators add accuracy and repeatability to PCB manufacturing

Some manufacturing processes require high precision -- printed circuit boards (PCB) production, for example.  In these instances, the capabilities of each component in a production system are critical. Although machine designers know pneumatic cylinders well, these cylinders struggle to deliver the accuracy and repeatability demanded by high precision processes. Many design engineers now turn to electric rod actuators for accuracy and repeatability and for better operating efficiency.

Electric cylinders essential to advanced conveyor system [Case Study]

Conveying systems are common in manufacturing. They can be straight-forward systems that take packages from point A to point B or complex ones for sorting and diverting.  Systems used in food processing also must handle washdowns, a common practice in the industry.

As critical components, linear actuators must withstand the challenges of the application including environmental ones.  Pneumatic cylinders have been used extensively in conveying. However, electric cylinder use is growing, fueled by demand for programmability and better accuracy.

Electric rod actuator cleans up after hydraulics

Hydraulic cylinders are well-known linear motion workhorses in industrial machinery.   They’re reliable, familiar, capable of high force, and affordable, but they’re not without disadvantages. The leading ones are fluid leaks, large footprint (with hydraulic power unit or HPU), cumbersome changeovers due to lack of programmability, and high maintenance costs.

The introduction of electric high force linear actuators means machine designers now have a choice. An electric rod actuator can replace a hydraulic cylinder and eliminate the need to clean up leaks.

Solid-bearing, belt-driven linear actuator handles harsh environment

Many applications call for the carrying action of a rodless electromechanical actuator. And many of these need the high speed and long stroke capabilities of a belt-driven linear actuator. But what do you do when your application is in a dusty, harsh environment? Many rodless electromechanical actuators can’t handle these conditions. Their roller bearings get clogged with dust and stop working. Could a solid bearing be the solution?
