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
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 has been […]
Miniature linear guides for mounting in tight spaces
IKO has expanded its LWL family of miniature guides with the addition of its newest LWLF2 linear motion rolling guide, which addresses the demand for device miniaturization with a compact, lightweight design that makes mounting easy in tight spaces. The new LWLF2 features the same ultra-small 2.5-mm height dimension as its predecessor, the LWL1. It’s […]
Ewellix launches intelligent SmartX platform for linear motion
Ewellix has launched an intelligent digital platform which will underpin a new and advanced generation of linear motion solutions. Called SmartX, the new digital platform has been designed to help engineers develop motion, robotic and automation systems that offer far greater levels of intelligence, connectivity and adaptability than are achievable from existing equipment. As a […]
Rod-style electric actuator designed to meet hygienic standards
A new RSH electric hygienic rod-style actuator from Tolomatic delivers clean, continuous control to automation machinery. RSH actuators are designed to help improve repeatability, enhance quality, reduce contamination potential and increase flexibility of hygienic machine designs, particularly for the food, beverage, medical, healthcare and pharmaceutical industries. “We designed the RSH for ‘mission critical’ hygienic applications,” […]
Linear rails from Rollon simplify design of high-performance automated systems
Rollon has upgraded its Telerace family of linear rails to help designers simplify projects and enhance the efficiency of automated systems. Two Telerace families of cold-drawn steel rails now feature induction hardened and ground raceways along with double-row ball bearings for greater load handling capability, longer life and reduced maintenance requirements. The newly enhanced rail […]
Rack and pinion drives: A new look at an old technology
Comparing rack and pinion drives with other linear drives such as belts and ball screws shows that sometimes simplicity can be the ultimate sophistication. YYC North America These days engineers have quite a few options for actuation in a linear motion system. From various screw drives to linear motors to hydraulic systems, each comes with […]
Renishaw’s on-machine tool measurement features expanded range, improved repeatability
Building on the success of the original NC4+ Blue, the latest evolution of the non-contact tool setter features an ultra-compact design and is now available in four sizes, with operating gaps ranging from 55 to 240 mm. Measurement repeatability has also been improved across the range, now down to +/- 0.5 micron on smaller separations. […]
Real-time special machining configuration added to online shaft selector tool
Thomson Industries, Inc. has added a real-time special machining configuration capability to its online shaft selector tool. The new functionality lets customers reduce the time spent in customizing round rail shafting for their application needs to mere minutes instead of hours or even days. Typically, a customer uses the Thomson shaft selector to specify materials, […]
New motor/actuator with integral controls from Curtiss-Wright
The newest motor/actuators with integral controls from Curtiss-Wright’s Actuation Division, the Exlar SA-R080 rotary and SA-L080 linear actuator, are the first 80-mm frame size in the harsh environment control and sense family of industrial electromechanical actuators from Curtiss-Wright. The SA series actuators offer force, precision, energy efficiency, and control while minimizing the additional cabling, external […]
