When it comes to specifying an electric linear actuator, selecting the right lead screw* (sometimes referred to as the leadscrew) for the application is critical. That’s because the screw is the major drive component in most electric actuators. After all, if it’s not a belt-driven actuator, then there’s a lead screw involved.

Linear actuators used in sawmills are often subjected to dusty and wet conditions. If the right electric linear actuator isn’t specified, the component may fail and cause expensive downtime. Given the pressure to keep production costs down and output up, it’s essential to match the actuator to the manufacturing environment.
A good way to do this is to refer to a rating system. We use the IP (Ingress or International Protection) system because it evaluates ingress of both dry particles and moisture. An application where there is both dust and water spray needs electric linear actuators rated IP67 for a high degree of protection.

Linear actuators are important pieces of industrial automation equipment. Without them parts wouldn’t move into place for the next production step, finished goods wouldn’t get to the right palate, and tools might not reach the spot they need to be in to do their work.
A lot rides on these automation components, so engineers need to know as much about them as they can. At Tolomatic linear motion is our core expertise. We watch what’s written in key trade publications. Here’s a round-up of recent articles that will help you learn more about linear motion.

Production cost and efficiency are important considerations in all manufacturing, but these factors take on critical status in some segments. Small-engine production is one of these. Using the right linear actuator can boost efficiency and reduce cost.

Conveying equipment manufacturers know that fast and efficient systems are critical to manufacturing success. Conveying system buyers are demanding better positioning accuracy, energy efficiency, and lower cost of ownership to ensure their ongoing success. Plus, some are eliminating compressed air systems and asking for electric linear actuators, including electric cylinders, instead of pneumatic solutions. Since they often produce several product models in the same plant, buyers need actuators that are easily programmable to several positioning set-ups.

Saving money is on everyone’s mind these days, especially when it comes to industrial automation. Automation is recognized as an important way to boost quality and productivity; however, the cost of adding automated systems can be daunting.
To keep costs in line, machine designers are often tasked with finding money-saving solutions. This doesn’t mean using the cheapest components, though. If a component has a low purchase price but is expensive to operate and maintain, it’s not a bargain. Smart engineers look at the total cost of ownership (TCO) of components they’re considering, including linear actuators.

Reducing manufacturing costs and improving product quality are driving forces in automotive manufacturing. Automation plays a key role in achieving these goals, and robots, especially welding robots, are an important part of the automation picture.
Resistance spot welding is used extensively in auto frame and body construction, and robotic welding lines are familiar sights in many plants. This type of welding requires speed, exact placement of welds, and precise pressure on weld tips. Most resistance spot welding robots rely on servo welding actuators to control cycle timing and pressure on weld tips.

Food processing is a tough environment for most automation equipment. There may be washdowns with high-pressure, high-temperature water. Caustic cleaning agents might be used. There also may be strict food safety standards to adhere to, like the USDA’s regulations for the meat, poultry and dairy industries. As automation components, all linear actuators, like electric rod actuators, need to stand up to the rigors of the food processing environment.

An electric linear actuator can outperform a pneumatic model with superior control of speed, position, and force as well as provide better accuracy and repeatability. But that superior performance comes with complexity. Pneumatic cylinders commonly are simple, easy-to-understand components, while electric linear actuators are systems comprised of a motor, controller, cables, and actuator. Plus attaching a motor to an actuator usually requires some kind of adaptor or housing.

Precision is integral to the aerospace and defense industries. Even a seemingly insignificant element of a device may be mission-critical, requiring the tightest manufacturing tolerances. That’s why when a rocket manufacturer contacted us about electric linear actuators that could hold their fuselage components in place for welding, we knew precise positioning would be a requirement.
