With the range of technologies, designs, and options available for linear motion components, ploughing through the alternatives and making the best decision takes more time and resources than many designers and engineers are able to expend on any individual component. Looking back at the top 10 most-read Linear Motion Tips articles of 2015 confirms this situation. From primers on […]
What is a crossed roller slide?
As their name suggests, crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground. The term “crossed” refers to the fact that the rollers are arranged in a crisscross […]
How to pick dovetail slides for durable designs
Christopher J Hetzer, CEO, Gilman USA The geometry of dovetail slides improves the precision of in-line movements for some machines. Dovetail-slide assemblies go into applications that need accurate linear strokes even under complex loading or nonstandard mounting arrangements. Like other linear-motion devices, they have a stationary rail (the base) and a moving carriage (the saddle). […]
How Seals Extend the Life of Linear Systems
When selecting a linear system – ball screw, linear guide, or actuator – most of the focus is on application data such as load, speed, travel, and duty cycle. But there’s another factor that should be considered, especially for technically demanding applications or harsh environments. That factor is sealing. How are the bearings protected against […]
Whispah Linear Slide suitable for non-contaminating linear motion applications
LM76 (www.lm76.com), a world leader in self lubricating linear motion bearings, has unveiled a linear slide ideal for non-contaminating linear motion applications such as pharmaceutical, medical and food processing equipment — the Whispah Linear Slide. Offering smooth motion, the new linear slide is exceptionally quiet and is low cost. The Whispah Linear Slide has been […]
Del-Tron Crossed Roller Tables
Del-Tron’s aluminum and steel crossed roller tables are the perfect choice for applications requiring high accuracy and exceptional load carrying capabilities. Accuracies range from 0.0001” per inch of travel straight line accuracy on our aluminum tables to 0.00008” of parallelism on our steel crossed roller tables and are capable of carrying loads in excess of […]
Significant Lead Time Reduction for Selected Thomson Linear Slides
WOOD DALE, IL – Thomson has significantly reduced lead times for some of its most popular Thomson slides. Lead times for Thomson 2DA, 2CA, 2BA, IB Series, IC Series, ID Series and IV Series linear guides have been reduced to just 2 days. Lead times for Thomson 2DB, 2EB, MS, 2HB, 2HE, 2RB AND 2RE driven […]
