Sourcing linear motion solutions from NSK’s global manufacturing sites

February 25, 2021 By Kelsey Zebrowski Leave a Comment

High-precision linear guides are an important product group for NSK’s Linear Motion Technology (Seiki) management unit. As a specialist in this field, the company meets the requirements of many demanding market sectors, including the machine tool industry. Many of the linear guides supplied to European customers operating in high-precision, high-quality sectors are application-specific or adaptations […]

Rails, screw assemblies boast 20,000 km travel without relubrication

February 12, 2021 By Miles Budimir Leave a Comment

ball rails ball screws

The BSHP ball rail systems and BASA ball screw assemblies from Bosch Rexroth now achieve lubrication intervals that are up to four times longer. In more and more applications, they can even be used maintenance-free over the entire service life of a component. As a result, low-maintenance or maintenance-free linear motion technology minimizes operating costs […]

What are low outgassing materials for linear motion components in vacuum applications

February 1, 2021 By Danielle Collins Leave a Comment

Outgassing — the release of gas or vapor from a material through desorption, sublimation (the transition of a material from solid directly to gas), or evaporation — is a critical parameter for materials used in vacuum environments. These gasses and vapors can affect the pressure (or level of vacuum) in the vacuum chamber, and outgassed compounds […]

New SureMotion LAHP Series linear actuators and slides from AutomationDirect

January 28, 2021 By Miles Budimir Leave a Comment

linear actuators

The SureMotion LAHP series linear actuators, slides, and accessories are XYZ gantry components that allow creation of a motion system with up to three axes of movement. These motor-ready linear actuators and sliding components have travel lengths of up to 910 mm. They turn rotary motion into linear motion and provide a variety of X-Y […]

Gothic arches, tracks, and roller bearings in the context of linear motion

January 27, 2021 By Lisa Eitel Leave a Comment

Industry terminology used to describe linear guides and other linear components widely varies. Here we explain three linear-guide phrases and words having multiple meanings — and differentiate how they relate to track-roller linear guides and profiled-rail linear guides. Let’s start by reviewing the multiple linear-motion meanings for Gothic-arch linear bearing. Gothic arches originate from civil […]

Functional safety (and IIoT connectivity) from linear brakes

January 27, 2021 By Lisa Eitel Leave a Comment

In a recent Design World feature, we covered the basics of how functional safety is quantified … and what constitutes a servo-brake option with functional-safety certification. Here we share more details on the construction of safety brakes for linear axes and the intersection of brake safety and IIoT capabilities. Machine safety is core to nearly […]

How to make linear motion systems cleanroom compatible

January 22, 2021 By Danielle Collins Leave a Comment

linear motion cleanroom

While we often talk about the importance of keeping contamination out of linear motion components such as linear guides and screws, when these systems are used in a cleanroom, the goal is just the opposite — to keep these components from introducing contamination into the environment. What exactly is a cleanroom? According to ISO 14644-1:2015, […]

Anti-friction miniature linear guides from PM B.V. now come with a variety of cage options

January 15, 2021 By Lisa Eitel Leave a Comment

When building miniature linear-motion systems, design engineers can choose between ball and crossed-roller linear guides.  When applied to precision systems, most all of these linear guides have cages to prevent shifting of the anti-friction rolling elements during operation … especially when these linear guides are applied in exacting microscopy, manipulator, and image-scanner applications — for […]

How do miniature profiled rail guides compare to their full-size counterparts?

January 14, 2021 By Danielle Collins Leave a Comment

The basic distinction between “standard” and “miniature” profiled rail guides is the width of the guide rail: profiled rails with a width of 15 mm or less — and the carriages that fit on them — are generally considered “miniature” by bearing manufacturers. (However, some manufacturers also produce 15 mm rail guides in standard versions, as we’ll […]

Precise miniature slide guides from NB Corporation

January 4, 2021 By Miles Budimir Leave a Comment

slide guides

SEBS-B type slide guides from NB Corporation feature standard radial clearances that are twice as accurate. The guides are available in both retained-ball (whose elements allow for easier handling because the guide block may be removed from rail without ball loss) or low-cost non-retained ball lines. Available sizes are from 2 mm with friction-free travels […]
