Ride the wave of electrification: Off-highway designs with linear actuators

February 23, 2021 By Lisa Eitel Leave a Comment

The transition of mobile machinery and off-highway equipment away from fossil fuels may be a long-term goal, but electrification is already delivering real benefits in the sector. By Tarek Bugaighis • Ewellix Is the era of the internal combustion engine coming to end? Under pressure to reduce harmful emissions, the automotive industry is already gearing […]

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 […]

When should you use a bronze lead screw nut?

February 8, 2021 By Danielle Collins Leave a Comment

Lead screw manufacturers offer nuts in a wide array of materials, including various plastics and grades of bronze. And while plastics garner a lot of attention for their versatility and range of suitable applications, lead screw nuts made of bronze are especially well-suited for applications with high loads or extremely high (or low) temperatures. Plastic […]

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 […]

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, […]

The top 10 linear motion articles of 2020

December 28, 2020 By Danielle Collins Leave a Comment

linear motion articles

Suffice it to say, pretty much everything about 2020 has been out of the ordinary, and our recap of the top linear motion articles for this year is no exception. For the first time in recent history, only one (1!) of the top 10 articles is about ball or lead screw technologies — a topic that usually […]

Ball screw seals: Types, options, and applications

December 10, 2020 By Danielle Collins Leave a Comment

Ball screws are used in a wide range of applications, many of which expose the screw and nut assembly to harmful contamination in the form of dust, chips, or liquids. And like any bearing that uses metal balls (or rollers) on metal raceways, ball screws can experience abrasive wear when exposed to solid contaminants, while […]

What’s the difference between a ball screw spline and a traditional ball screw?

October 1, 2020 By Danielle Collins Leave a Comment

ball screw spline

A ball screw spline is a combination of two components — a ball screw and a rotary ball spline. By combining a driving element (the ball screw) and a guiding element (the rotary ball spline), a ball screw spline can provide both linear and rotary motion, as well as spiral motion, in a highly rigid, […]

Choosing the correct drive screw type is critical to getting the best actuator performance, accuracy, and repeatability Chris Maupin Program Manager and Engineer Hunt Valve Actuator Division Screw drivetrains are the most common types of electromechanical linear actuators. A screw drivetrain acts as a linear force generation system, converting a rotary torque input from a […]

How to protect ball screws in harsh environments

August 28, 2020 By Danielle Collins Leave a Comment

Harsh environments can wreak havoc on motion system components — especially rolling element systems such as linear guides and ball screws. And while protective devices such as rail covers, wipers, and scrapers are widely available for linear guides, protecting ball screws in harsh environments is a bit more tricky. But despite being more difficult to […]
