Belt-driven linear actuators feature greater load capacity

April 22, 2022 By Miles Budimir Leave a Comment

linear actuator

Rollon has updated its SMART SYSTEM lineup of belt-driven linear actuators with a rugged new design that supports heavy loads and ensures low maintenance operation in automated manufacturing, packaging machines and food and beverage equipment. The actuators have a self-sustaining anodized aluminum frame and a steel reinforced driving belt, and are engineered to provide stiffness […]

What is a high helix (high lead) screw?

April 14, 2022 By Danielle Collins Leave a Comment

Ball and lead screws are specified by the diameter of the screw shaft and the lead (or, in some cases, pitch) of the screw thread. The lead, which specifies how far the nut travels for each revolution of the screw, is created by the thread, or helix, that wraps around the screw shaft. If the […]

How to calculate duty cycle and what it means for machine life

April 4, 2022 By Danielle Collins Leave a Comment

linear rails

Determining the life of a linear system that uses balls or rollers is relatively straightforward, thanks to the L10 bearing life equation, which gives life in meters of travel (for linear bearings) or revolutions (for screws). And for plain bearings and lead screws, manufacturers typically use the bearing’s PV value and operating conditions to provide an […]

Screw drives see new uses in robotics, other applications

April 1, 2022 By Miles Budimir Leave a Comment

ball screws

Some of the surest, time-tested methods of linear actuation are screw drives. Whether lead- or ball- or roller screws, screw actuation remains a large part of the linear actuation equation, thanks to their reliability, accuracy, and relative simplicity of operation. Recently screw drive developments have included advances in materials as well as manufacturing methods leading […]

Pandemic impacts linear motion component manufacturing, applications

March 31, 2022 By Miles Budimir Leave a Comment

automation

Linear motion components include everything from various types of linear actuators to linear guides, slides and ways, and a host of components in between. One thing they all have in common is that their development and production are influenced by both technological trends as well as broader market forces. One of those forces is has […]

Comparing micropositioning and nanopositioning stages

March 29, 2022 By Danielle Collins Leave a Comment

ASML Lithography Machine

Linear stage designs can range from long-stroke, high-load gantries to micropositioning and nanopositioning stages with light payloads. Although all linear stages are designed and constructed to provide high positioning accuracy and repeatability and to minimize angular and planar errors, stages for micropositioning and nanopositioning applications require additional considerations in component selection and design to achieve these […]

Part 2 of 2: Electric actuators as an alternative to hydraulic cylinders

March 16, 2022 By Lisa Eitel Leave a Comment

Here we offer some tips for converting a fluid-power-driven axis to electrical actuation. By Ryan Klemetson • Business Development Manager | Tolomatic, Inc. As explained in Part 1 of this article series on motioncontroltips.com, hydraulic systems offer long service life, but they’re not as efficient as electric systems. Electric systems also provide precise position, velocity, […]

What is an inverted roller screw and how does it work?

March 14, 2022 By Danielle Collins Leave a Comment

inverted roller screw

Roller screws are often thought of as the standard planetary design, but several variations exist, including differential, recirculating, and inverted versions. Each design offers unique benefits in performance capabilities — load capacity, torque, and positioning — but the inverted roller screw’s primary strength is its ability to be easily integrated into actuators and other subassemblies. Recall that […]
