DESTACO now sells cost-effective OEM gripping setups … and the new T110 linear pneumatic table slides complement the G110 gripper series favored by OEMs. Together, they deliver improved speed and reliability versus comparable products on the market for high-speed machine part-transfer, pick-and-place operations, and machine tending applications. Engineered for better performance, lower maintenance and faster operation, […]
Gallery: Crossed-roller slide variations and uses
Precision rail guides known as crossed-roller guides (also called crossed roller slides, linear bearings, or ways) are linear-motion load supports that incorporate arrays of cylindrical roller bearings for the reduction of friction. These crossed-roller slides contain the rollers between solid twin guide bars (usually made of through-hardened tool steel) cut with V-shaped grooves that are […]
When to consider crossed roller slides
When an application requires a linear guide with high load capacity, high stiffness, and good travel accuracy, the range of suitable products is typically narrowed down to two designs: recirculating linear guides and crossed roller slides. Where recirculating linear guides use balls to support the load, crossed roller slides use rollers. The rollers ride in […]
Del-Tron Precision now has ISO 9001:2015 Certification
Linear-motion manufacturer Del-Tron Precision, Inc. has earned ISO 9001:2015 certification. The comprehensive system audits covered every aspect of operations. “Any company that has been through the certification process knows that achieving ISO 9001:2015 certification is demanding,” said Ralph McIntosh, President of Del-Tron Precision, Inc. “Each individual in our operation must be wholly dedicated to the […]
What are the differences between plain and rolling linear guides?
A linear guide (or linear bearing) is a mechanical element that allows relative motion between two surfaces, with one surface supporting the other, and minimum friction between the two. There are two basic types of linear guides: plain and rolling element. While their general function is the same, their design and performance differ significantly. Linear […]
The top 10 Linear Motion Tips articles of 2015
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 […]
