LINAK has launched a powerful new actuator, the LA33. The electric linear actuator is a mid-range powerhouse built upon 35 years of specialized knowledge accumulated at LINAK. The LA33 shares the same advantageous features of all the actuators in the LINAK family including the LINAK Integrated Controller, Hall sensors for relative and absolute feedback, proportional […]
Linear encoders for motion applications
Whether a linear system uses servo or stepper motors, adding a linear encoder can improve the performance of the machine and the quality of the process. In servo applications, the motor’s rotary encoder monitors its speed and direction, but a linear encoder monitors the load’s actual position. When stepper motors are used, position monitoring is especially important, […]
A user’s guide to sensors and switches
Users have an array of choices when it comes to choosing sensors for electromechanical actuators. Some actuator manufactures offer one or two varieties of sensors as standard options, depending on the construction of the actuator and its most common uses, while others leave the selection entirely to the user. Whether you’re choosing among the options […]
New economical linear slide from PHD
Built on the foundation of long-life products for industrial automation, PHD Optimax actuators are designed to meet machine builders’ performance requirements at a competitive prices. These economical, efficient, and reliable actuators provide an alternative choice to PHD’s standard “built-to-order” product line, delivering even more cost-effective solutions to meet industrial application needs. In a continuing effort […]
Nook Industries Introduces Modular Actuator Calculator
Nook Industries, a leading innovator of linear motion components and systems, has introduced an engineering calculator for modular actuators—one of the only of its kind in existence. The calculator works by simply choosing the desired product, entering its load definitions and allowing the tool to calculate the bearing stress and load to determine the bearing […]
The difference between inertia and momentum
The concepts of inertia and momentum are often confused — possibly due to the similarity of their definitions. Inertia is generally described as an object’s resistance to motion, with momentum being the tendency of an object to continue moving. Both have implications for linear motion applications, but while inertia is a fundamental sizing parameter, momentum […]
A selection guide for linear systems
Gone are the days when machine designers and builders had to choose between constructing their own linear system from scratch or settling for a limited range of pre-assembled systems that, in most cases, were an imperfect fit for their application. Manufacturers today offer systems based on a range of drive mechanisms—ball screws, belts, rack and pinions, linear motors, […]
ATEX rated explosion-proof linear actuators
Curtiss-Wright Corporation has expanded its Exlar® linear actuator line to include the EL120 explosion-proof linear actuators. The EL120 linear actuators meet ATEX requirements for use in potentially explosive atmospheres and are in conformity with the EU ATEX Directive 94/9/EC, as well as the IECEx scheme. Additionally, they are rated for Class I, Div 1, Groups B, […]
New video demonstrates how to synchronize multiple lifting columns
Thomson Industries, Inc., a leading manufacturer of mechanical motion control solutions, has released a new video to demonstrate how design engineers can synchronize multiple Thomson Lifting Columns quickly and easily. The compact design of Thomson Lifting Columns provides a favorable ratio between stroke and retracted length to improve operator ergonomics. Models are designed to handle moment loads […]
Hardened way slides provide durability for long-life operations
Gilman Precision explains the basics of a hardened way slide, including which applications they are good for and how to keep yours in great working condition. Predominantly used for high production, hardened way slides provide linear rigidity for heavy duty applications. “A hardened way slide is a linear positioning device that incorporates precision, ground rectangular […]
