Screw machines are specialized automated metalworking lathes that were first developed in Switzerland during the late 1800s to produce large numbers of identical parts such as screws. At that time, ...

Here’s a little engineering quiz for you: If an app needs to move a 500 kN axial load along a 1,500 mm stroke, is it best to use a roller screw or ball screw? If you instinctively said roller screw, ...

Determining the service or useful life of screw actuators – lead (acme), ball, and roller screws is a fundamental problem that faces many motion-system designers. In a broad sense, a screw’s service ...

Ball screw mechanisms represent a critical class of precision drive components that convert rotational motion into linear motion by utilising recirculating ball bearings. This conversion is achieved ...

The Large Bearing Testing Machine has been developed and primarily used for commercial testing of large bearings. It is capable of applying 1,600 kips (7,117 kN) vertical load, and lateral ...
