Nook Industries Introduces Modular Actuator Calculator

★ By Danielle Collins Leave a Comment

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

★ By Danielle Collins 1 Comment

Inertia 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

★ By Danielle Collins

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, […]

When Do You Need a Gantry Robot?

★ By Danielle Collins 7 Comments

Festo-3d-Gantry

When you think of an industrial robot, what comes to mind? Probably something like this… Articulated robots like these are widely recognized, thanks to car company commercials and robot dance sequences. SCARA (Selective Compliance Articulated Robot Arm) robots are also well-recognized due to their adoption and proliferation in factories since the early 1980’s. Both of these – articulated […]

How to make your linear motion technology easy to maintain

★ By Danielle Collins 1 Comment

Adding linear motion to articulated robots adds flexibility and extends the work envelope of your system. The 7th axis tracks that enable this linear motion all provide the same functionality but differ in one significant design feature: the antifriction bearing system used to support and guide the tracks. Watch this video to learn how to select the […]

Inertia Matching: Why Perfect Isn’t Always Best

★ By Danielle Collins 9 Comments

Newton's Cradle

Inertia matching is one of the inexact sciences of motion system design. When a motor and a load are coupled together, the ratio of load inertia to motor inertia determines how well the motor can control the load during acceleration and deceleration. In theory, a “perfect” inertia match of 1:1 (load inertia equals motor inertia) should […]
