PBC Linear has recently released a low profile linear guide system, the Compact Series. This addition to the Mechantronics Enabled initiative is designed to provide smooth, accurate, and repeatable linear motion in tight spaces. Boasting a 23 mm standard height, and with the flexibility to be configured to adapt to the demands of a given […]
Ball + leadscrew driven
A selection guide for linear systems
Gone are the days when machine designers and builders had to choose between constructing their own linear system from scratch or settling for a limited range of pre-assembled systems that, in most cases, were an imperfect fit for their application. Manufacturers today offer systems based on a range of drive mechanisms—ball screws, belts, rack and pinions, linear motors, […]
Compact Stages for Scanning and Indexing
The Velmex XSlide assembly is a compact positioning stage highly suitable for high performance incrementing and scanning of smaller loads. Its compact design makes it ideal for limited space applications. Constructed with hard-coat anodized aluminum dovetail ways and smooth motion PTFE bearings, XSlide assemblies deliver higher rigidity for longer life and more precise movement when […]
How to avoid ball screw buckling
Imagine two columns—one short and wide and the other long and narrow. As you begin to put weight on them, the long, narrow column gradually begins to bend, to the point that it becomes permanently deformed and eventually breaks, while the short, wide column handles the weight with ease. In the same way the long, […]
Low cost, high precision vertical lift stage
The AT10-120 motorized vertical stage from Optimal Engineering Systems, Inc. (OES) is a high resolution, low profile, high load vertical lift stage that can be easily integrated into almost any application. The large 220 x 140 mm (8.7 x 5.5 in.) drilled and tapped platform has a vertical travel of 110 mm (4.3 in.). The […]
Programmable actuators available with ball screws or Acme screws, and servo or stepper-drive systems.
Nook Industries’ line of Series 500 programmable actuators are designed for continuous duty and long service life. The Series 500 uses a direct or toothed-belt drive for better mechanical efficiency, while also allowing quieter running performance. Ball screw-driven programmable actuators are available in parallel and in-line models with either a servo motor or stepper motor. […]
ATEX rated explosion-proof linear actuators
Curtiss-Wright Corporation has expanded its Exlar® linear actuator line to include the EL120 explosion-proof linear actuators. The EL120 linear actuators meet ATEX requirements for use in potentially explosive atmospheres and are in conformity with the EU ATEX Directive 94/9/EC, as well as the IECEx scheme. Additionally, they are rated for Class I, Div 1, Groups B, […]
New video demonstrates how to synchronize multiple lifting columns
Thomson Industries, Inc., a leading manufacturer of mechanical motion control solutions, has released a new video to demonstrate how design engineers can synchronize multiple Thomson Lifting Columns quickly and easily. The compact design of Thomson Lifting Columns provides a favorable ratio between stroke and retracted length to improve operator ergonomics. Models are designed to handle moment loads […]
Top ballscrew trends: More capacity and miniaturization
Ballscrews are a mainstay in motion applications, partly because their performance is so predictable, and they’re relatively easy to design into machinery. Over the last few years, advances in manufacturing and materials have improved ballscrew performance so OEMs today can get better linear motion with them at lower cost. For starters, the latest generation of […]
Micro Series lead screws now available from Haydon Kerk Express web store
Haydon Kerk Motion Solutions has added Kerk® Micro Series lead screws to the Haydon Kerk Express web store with three different leads available for 24-hour shipment. Standard and prototype-style nuts also are available. Haydon Kerk has applied its extensive knowledge and experience in precision thread rolling to a new range of micro-sized lead screws. Its […]
