Technology trends in electric actuator design continue from years past, influencing manufacturers offerings to designers. For instance, electric actuators are easier to specify and install, with more application-specific models on offer. This tracks with other trends including the move to more integrated motion designs, opening up more and varied applications for electric actuators. Here’s what […]
Linear Actuators
U.S. Tsubaki debuts new Zip Chain Linear Actuator
U.S. Tsubaki has launched its new Zip Chain Actuator. The Tsubaki Zip Chain Actuator is a revolutionary electric linear actuator that provides high speeds and multi-point stopping in a compact footprint. The Tsubaki Zip Chain Actuator is a linear actuator that “zips” together specially segmented chain using a custom designed sprocket. This “zipping” action creates […]
Electric cylinder features zero cogging, high throughput
Moticont has added a non-commutated linear actuator to its DDLM series of low cost actuators. This new DDLM-019-070-01 Linear Actuator can develop 10.1 oz (2.8 N) of continuous force and 32.1 oz (8.9 N) of peak force at 10% duty cycle. Having a stroke of 0.960 in. (24.4 mm), this clean, fully enclosed linear actuator, […]
How to pick the right drive screw
Choosing the correct drive screw type is critical to getting the best actuator performance, accuracy, and repeatability Chris Maupin Program Manager and Engineer Hunt Valve Actuator Division Screw drivetrains are the most common types of electromechanical linear actuators. A screw drivetrain acts as a linear force generation system, converting a rotary torque input from a […]
Low-cost, high-performance alternative to rod actuators, pneumatic cylinders
Bell-Everman’s new ServoBelt RA is a high-performance, drop-in replacement actuator designed for applications that have traditionally used rod actuators, pneumatic cylinders or even linear motors. Unlike traditional rod actuators, ServoBelt RA is fully guided along the entirety of its stroke, making it more resistant to off-axis loads and more stable in on-axis moves. With linear […]
Tolomatic expands hydraulic-class electric actuator force range to 50,000 lbf
Tolomatic’s expanded extreme-force electric actuator family now includes the RSX128 actuator, rated up to 50,000 pounds of force (222.4 kN). Ideal for replacing hydraulic cylinders and designed for 100 percent duty cycle, the RSX actuator features Tolomatic’s precision-ground planetary roller screws for long, consistent operating life in challenging environments. Applications include assembly, metal fabrication (pressing, […]
Tolomatic develops open-source, low-cost ventilator actuation prototypes for COVID-19 patients
In an effort to support the global need for medical ventilators, Tolomatic has dedicated a team of engineers to the development of highly efficient emergency ventilator concept systems using electric linear actuators. Tolomatic’s solution is a new type of ventilator that operates using an electric linear actuator. These prototypes automate a non-invasive, positive-pressure resuscitator (also self-inflating […]
Out with the oil, in with the screw
A new generation of electromechanical actuators is replacing hydraulic cylinders in demanding applications. Increasingly, that choice is being driven as much by cost advantages as by performance. Tarek Bugaighis Ewellix Traditionally, when engineers wanted to produce large forces or move heavy loads their first choice would be hydraulic actuation. Today, however, hydraulic systems have a […]
High load capacity actuator from NB Corporation
This compact single axis actuator from NB Corporation features a unique “U” shaped integrated slide guide and ball screw. The BG actuator’s highly rigid structure may be one-end supported. The 4 ball circuits contained in its slide block deliver high load capacity, accuracy and rigidity. The product catalog supplies all dimensions, drawings and ratings necessary […]
New IoT-ready electro-mechanical actuators from Ewellix
Ewellix, formerly SKF Motion Technologies, has developed new actuators which deliver forces up to 82 kN and speeds of 1 m/sec, to provide real-time, accurate information that improves machine productivity. With the newly designed Ewellix actuators, production line upgrades are now possible without major modification of existing machine layouts. The new CASM-100 and LEMC actuators […]
