Motion Trends: Applications expand for versatile lead screws

March 22, 2019 By Miles Budimir Leave a Comment

lead screw

Improvements in lead screw designs have meant screws that are increasingly competitive with other types of drive screws, including ball screws. For instance, lead screws can offer shorter lead times and better performance, all at a lower cost than other screw technologies. Quite a few lead screw manufacturers offer a range of anti-backlash options, superior […]

New bearing from igus assists in quick, easy liner replacement

June 6, 2018 By Miles Budimir Leave a Comment

linear bearing

igus has introduced a new bearing, drylin W Exchange, for its drylin W linear system in which the liner can be replaced directly on the rail without dismantling the system. By using a practical assembly tool, users can push the old liner out of the housing, clip the new one on to the shaft and […]

Motion and control objectives for automated storage and retrieval systems

August 21, 2017 By Danielle Collins 1 Comment

Automated storage and retrieval

Automated storage and retrieval systems are a key enabler of the next-day delivery we’ve come to expect from online retailers. But like other types of automation, AS/RS equipment must meet the customer’s objectives for safety, footprint, and energy efficiency. It used to be that as you drove through industrial suburbs, just beyond cities such as […]

What is stick-slip?

December 1, 2016 By Danielle Collins 2 Comments

Stick-slip, also referred to as “stiction,” is the bane of engineers and machine builders who need smooth, precise motion. Simply put, it’s the jerkiness that can plague both plain and recirculating linear bearings when they transition from standstill to motion. Here’s why stick-slip happens… When two objects slide against each other, friction works against their motion. […]

Guide systems that turn corners

October 26, 2016 By Danielle Collins 1 Comment

curved guides

The shortest distance between two points may be a straight line, but some applications dictate moving in curved sections and around corners. When two or more axes are combined, as in a Cartesian or gantry system, a method of control called contouring can be used to create radii and round the corners of traditional rectilinear coordinates. […]

New curved linear guides for variable radii from igus

September 29, 2016 By Miles Budimir Leave a Comment

linear guides

Based on the proven line of drylin W linear plain bearings, igus has now introduced linear rails bent to custom radii, along with adaptable carriages that can self-align between straight linear runs and curves without binding. According to Matt Mowry, Product Manager for drylin linear and drive technology at igus Inc., this new addition to […]

A guide to plain bearing materials in linear motion applications

September 19, 2016 By Danielle Collins 2 Comments

plain bearing

One of the benefits of plain linear bearings is their simplicity. Especially when compared to recirculating bearings, plain bearings are easy to specify, install, maintain, and replace. But don’t let that simplicity fool you. Choosing the wrong bearing, or more specifically, the wrong bearing material, can result in poor performance, degradation of the bearing, or […]

Variable width and length linear axes

September 13, 2016 By Danielle Collins Leave a Comment

linear axes

Now configure toothed-belt linear axes in customizable sizes To simplify product selection of maintenance-free, self-lubricating linear guides, motion plastics specialist igus has developed a modular construction kit for belt-driven DryLin ZLW linear axes. With the new “ZLW toolkit,” customers can customize their own solutions, including rail widths, system length, etc., even for small installation spaces. […]
