What’s the use of a force versus linear velocity chart?
Force versus linear velocity charts are mainly a tool for engineers specifying screw-based linear actuators. In short, the charts help engineers pick the actuator screw resolution after settling on a given actuator frame size. Much like references that describe the capabilities of rotary motors alone, there are similar metrics that describe the capabilities of linear […]
Thomson FSI style Metric Precision Ball Screws now have faster delivery times
Thomson Industries, Inc., has further enhanced its customer offerings in North America by utilizing its domestic manufacturing facilities to deliver high-quality, German-engineered metric ball screws with shorter lead times. As only two percent of all metric ball screws sold in North America are manufactured domestically, customers typically are forced to wait up to 10 weeks […]
How to choose end fixity conditions for screw applications
Ball and lead screw assemblies consist of three main components: the screw shaft, the ball nut, and the end support bearings. More than just an accessory, end support bearings have a significant influence on the rigidity, maximum speed and buckling load of screw assemblies. There are two primary types of support that can be implemented for […]
How to calculate motor drive torque for ball screws
When sizing a motor, one of the most important factors is the required torque. In general, motor torque-speed curves outline two primary areas of permissible torque: continuous and intermittent. Intermittent motor torque is allowed only for a short time (specified by the manufacturer) and in most cases is the torque required during acceleration. A motor’s […]
New 24V integrated electric actuators rated to 100 N thrust
Servo2Go.com has just added new additions to its broad range of cost-effective 24V electric linear actuators from Dyadic Systems. The SCN5 series actuators are compact yet powerful integrated mechatronic cylinders that feature a motor, encoder, drive and actuator in one integral package. Dyadic Systems has developed the linear actuator drive mechanism such that the screw and […]

Tolomatic ERD all-stainless hygienic electric actuators with new roller screw choice are designed for 100 percent duty cycle and can be deployed in the most demanding of applications, including food and beverage processing. The Tolomatic ERD hygienic all-stainless-steel electric cylinder features a new roller screw option that increases the maximum thrust to 7868 lbf (35.6 kN) for expanded cylinder […]
As the screw turns: What are pros and cons of different linear screw-drive actuators?
Travis Schneider, Product Manager, Automation Group, Parker Hannifin Understanding the pros and cons of different linear screw drive actuators helps you make the best choice for your application. Screw drivetrains are among the most common types of electric linear actuation used in industry today. However, given the range of options available, finding the best solution […]
Tips for preventing linear bearing corrosion
Corrosive environments can include anything from detergents and chemicals for washdown (the high-pressure cleaning of equipment), to acid baths and their related vapors, to chemicals in food processing. Because profiled linear rails, round shafts, and ball screws are made primarily from steel components, they’re highly susceptible to corrosive agents, which can quickly cause rust, pitting, […]
What are the main types of linear actuators?
Updated August 2017 || Linear actuators come in myriad configurations to suit almost any application, environment or industry. They’re primarily categorized by their drive mechanism; then manufacturers use other features such as the type of guide and housing to further differentiate them. Below is an explanation of the most common linear actuator categories. Belt-driven and […]
