This article describes a series of tests that can be performed by the average user, with little experience, and without sophisticated measuring instruments, to quickly determine the most important performance characteristics of linear motion systems.
News From the Industry
A reader asks for clarification on last issue's Ask the Expert column about ball screw sizing.
Automated production of large objects such as auto body prototypes, boat hulls and surfboards traditionally requires computerized numerical control (CNC) systems costing nearly a million dollars. Thomson Cuts Costs and Production Time for Autoscale Inc.
In today's highly competitive world, the better someone understands the advantages and benefits of direct drive technology, then the more they will have an advantage in machine building, giving them an edge over their competition.

When the need arises for linear motion or positioning, there are many choices. One can use an Acme screw, ball screw, rack & pinion, or belts. The cost of a linear motor solution is generally greater than a mechanical linear product, but when one needs highly accurate, repeatable, high-speed motion, then the answer may be a linear motor.
Smart actuators bring big benefits to utility and other off-highway vehicles
How to select a guide wheel with the properties best-suited for a given application to create a system that reduces design costs and engineering changes, and lowers warranty, assembly, installation and mounting costs.
Increasing pressure on many fronts is compelling mine operators to thoroughly examine every phase of their operations. Fluctuating demand that whipsaws mineral prices, government-imposed environmental regulations and rising operating costs related to maintenance downtime all pose serious challenges for the mining sector. Add pressure from customers and stakeholders for more sustainable operations as well as union demands for higher wages, and you have a scenario that requires mine operators to exercise every possible option to achieve more efficient operations.
U.S. manufacturers, such as food processors, face an unprecedented competitive environment and must look for ways to be profitable without negatively affecting the quality of finished products.
A reader asks whether sleeve bearings can take the place of more expensive tilting pad bearings in a high-speed compressor application.
Rolling element or sleeve bearings often are required to operate under extreme conditions. In these instances, it is more important than ever to follow proper lubrication selection and maintenance procedures to maximize effective life and efficient performance.
Slow speed operation of fan systems within the air handling industry is generally performed due to two reasons: a coast down operation is required for hot (induced draft) fans to cool down before shutdown (often by using a turning gear), and operational efficiency improvements can be achieved during non-peak periods by slow speed operation using a VFD. In either case, when these fans are supported by hydrodynamic bearings, it is the oil film thickness developed from the bearing-shaft interaction that limits the minimum speed that can be maintained without causing premature wear and bearing failure. This paper will present a brief overview of lubrication theory and critical design parameters to achieve slow speed operation.
In 2017, there's more variety to be found under the hood of a car than ever. Electric, hybrid and internal combustion engines all sit next to a range of transmission types, creating an ever-increasingly complex evolutionary web of technology choices for what we put into our automobiles. But every evolutionary tree has a few dead end branches that ended up never going anywhere.
This Q&A session with various experts at Thomson Linear Systems covers linear slides & stages, clutches & brakes, bearings and actuators.
Ball screw assemblies are key to this patent-pending oilfield corrosion prevention solution.
