Motion system applications: Better ballscrews, more applications
Ballscrews suit applications needing light, smooth motion, applications requiring precise positioning, and when heavy loads must be moved. Examples include machine tools, assembly devices, X-Y motion and robotics. Factors such as lead accuracy, axial play and preload, and life-to-load relationship are most commonly used to classify ballscrews. Lead accuracy is the degree to which the shaft’s […]
When do you need a ball screw?
The gap is narrowing between applications that require ball screws and those that are suitable for lead screws, and it’s becoming more difficult for engineers and designers to determine which technology is best for their machine. Advances in lead screw designs and materials have given them higher load capacities and better positioning accuracy, making them a sound choice […]

How to shrink the size of a linear actuator
Linear actuators come in a wide range of sizes, and over the past several yeas, manufacturers have been emphasizing more and more compact footprints. But no matter how small the actuator, the addition of a motor can make the overall size of the complete system too large for space-constrained applications. Some manufacturers are addressing this issue […]
Can stack linear actuator provides exceptional performance

These 20 mm linear stepper motors offer an optimized design ideal for applications demanding high linear force. The new 20DBM features an optimized magnetic circuit which provides improved performance over existing designs The 7.5 degree step angle provides finer incremental […]
Exposing the myth of zero-maintenance ball screws
Surface degradation due to friction typically arises from lubrication problems. Linear-motion designs that address this problem are realistic, effective, and affordable. By Bruce Gretz, Executive V.P. | Steinmeyer Inc. Maximizing uptime and avoiding downtime for unscheduled maintenance are key to productivity. Mechanical wear of moving parts, particularly the positioning systems, is the most common reason […]
Precision ground ball screw options for linear motion applications
by John Feitl, Senior Application Engineer and Larie Butler, Marketing Communications Specialist, NSK Americas Ball screws have an efficiency that makes them suitable for use in actuators that drive industrial and automotive applications, including robotics, machine tool axes, and semiconductor wafer-transport systems. Here we review the different ball screw subtypes and where each one excels. […]
