Working with Linear Bushings Pt 3: Length, Load, and Surface Treatment

Simple linear movement could be achieved using simple parts but as designs evolved and demand increased so did mechanical parts.  Diving into linear bushings specifically, there are a variety of types to accommodate for different loads.  Bushing length and load ...

Working with Linear Bushings Pt. 2: Bushing Comparisons

Linear guiding devices are the most frequently used motion elements on automation equipment for palletizing, transferring, positioning and assembling. Here, linear bushing application tips will be explained along with comparisons of [1] Linear Bushings, [2] Linear Guides, and [3] Plain Bushings. Comparison ...

Working with Linear Bushings Pt 1: Linear Guide Mechanisms

Engineers have many options when it comes to designing for linear motion.  The need for compact and efficient designs evolved the variety of linear guide mechanisms.  Rails and sliders are the simplest form of linear guide mechanisms, which are a ...

Introduction to Working with Linear Bushings: Bushings vs. Bearings

Continuing with the Linear Motion theme, up next, bushings, bearings and other linear mechanisms are examined.  Beginning with an explanation of bushings versus bearings. Dynamic bearing systems are, at their most basic level simply an engineered hole/shaft interface that is ...

Mastering Ball Screws Pt. 4: Increase in Ball Screw Speeds

The need for speed! Increasing speed will increase accuracy and there are a variety of challenges to overcome to get that optimization.  To review, a ball screw is a mechanical element that converts motor’s rotary motion into linear motion.  Therefore, ...

Mastering Ball Screws Pt 3: Ball Screw Operating Performances

Friction is one factor in ball screw performance.  There are 2 different friction torques affecting screw operation performance.  Each friction torque is dependent on the type of feed screw. Feed screw is a mechanical element used to convert rotational motion ...

Mastering Ball Screws Pt. 2: Ball Screw Preloads

Preloading is used to increase the feed accuracy and rigidity of ball screws. Why is this necessary? In many applications utilizing ball screw actuation, position accuracy is of utmost importance. With many ball screw driven actuators, position accuracy can be achieved ...

Mastering Ball Screws Pt. 1: Steel Ball Recirculation System and Characteristics

Ball screws are one of the many components seen throughout factory automation applications. Using the same concept seen with a bolt and nut, this assembly uses the rotary motion of the screw to actuate the nut in a linear direction. ...

An Introduction to Aluminum Extrusion and Profiles

The aluminum extrusion (also known by ‘aluminum frames’) forming process is a bulk plastic deformation process. First, a billet of aluminum is preheated to a specified temperature that is still comfortably below the material melting point in order to facilitate ...
