New technologies for linear motion: Forgiving linear encoders and more
From nanometer resolution to high-force actuation, components for linear motion systems are changing with the times. Linear motion components such as encoders and actuators are evolving to meet the demands of new applications and industries. New demand in areas like medical devices, for instance, calls for more nimble, smaller components adaptable to new environments and […]
New video helps engineers service the Thomson Motorized Lead Screw
Thomson Industries, Inc. has released a new educational video to help design engineers correctly service the Thomson Motorized Lead Screw in the field. The precision-engineered units combine a hybrid stepper motor and lead screw in one compact envelope to provide clear advantages with a solution that is smaller, stronger, and more efficient than alternate technologies. […]
Don’t rule out leadscrews
by Robert Lipsett, Site Leader and Engineering Manager, Thomson Industries Here we explain where leadscrews excel in linear-motion applications. Then we explain how to apply them. Ballscrews are often the first choice for linear-motion applications because the use of recirculating ball bearings provides high efficiency, load capacity and positioning accuracy. However, with careful attention to […]

Compact Series from PBC Linear offers low profile linear motion solutions
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 […]
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 […]
