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, ...

When it comes to CNC machines, your SureFine has screws on its axes, and the Bodgeport does too. A shopbot has an amazing rack gear system, but when you start to dig into the small CNC routers ...

Planetary roller screws provide significant benefits over other screw-type actuators in terms of performance, load capacity, duty cycle, and lifetime. Traditionally, however, those benefits have come ...

Ball screw drive systems are pivotal in modern machine tools, providing the precise conversion of rotary motion into linear movement. Their high stiffness and efficiency render them essential in ...

An age-old engineering problem: how do you precisely measure the forces that act between two components inside a machine or, for example, on the sail of a boat without drilling holes or sticking on a ...
