Design Engineer’s Guide - Selecting a Lubricant for Ball Screws
Whether the design engineer selects a rolled ball screw or a precision ground ball screw, the lubricant should also be carefully considered. A properly selected lubricant minimizes friction, reduces torque, increases the screw’s efficiency, and extends life. Lubricants maintain the low friction advantage of ball screw assemblies by minimizing the rolling resistance between balls and grooves and sliding friction between adjacent balls.

Ball Screws and Lead Screws – The Real World Difference
There is a general distinction between the applications for a ball and lead screw. Lead screws are applied in OEM applications where a “just right” solution is required. Lead screws can be easily tailored to provide the required performance for the right applications at the lowest cost. This sometimes requires life cycle testing in the design phase but for an OEM, the extra up front work is well worth the product cost savings.

Steer-by-Wire Systems with Integrated Torque Feedback Improve Steering Performance and Reduce Cost
Hydraulic steering systems have long dominated the industrial utility vehicle market because of their familiarity both to vehicle designers and operators. More recently, a trend has been seen towards the use of electronic steer-by-wire systems that provide greater design flexibility by enabling software to customize the connection between the steering wheel and steering mechanism.
