Precision ball screw life expectancy
Typically, our precision ball screws are rated for millions of millimetres of travel at the rated dynamic load. However, they will travel farther than this at lower stress limits. Interestingly the load-life relationship is an inverse cube relation. For example, by reducing the load by half can increase the life by eight times.

Simple Bidirectional lead screw devices
Take a left handed and right handed trapezoidal thread from and accurately join them together and you have a simple gripping or expanding device. Numerous customers have used this concept within their machines. By being able to utilise the large range of lead screw diameters, as well as pitches, opens up the products possibilities.

High Helix Lead Screws
If you need to move a load quickly for a low rotational input speed, then perhaps consider the high helix lead screw ranges which can offer leads of up to 6 x the diameter of the screw. This multi-start...

Self reversing screws
A traditional lead screw and nut combination requires the driven screw to change its direction of rotation to enable the nut to return to its original start position. However, in certain applications, it may be advantageous to maintain a single direction of rotation of the screw but still have the nut return to the start position.

Ultra finite thread leads with Satellite roller screws
A satellite roller screw can be designed to deliver incredibly small and accurate leads than ballscrew designs. The lead of roller screws (axial travel per revolution of the screw) can be very manufactured with finite tolerances and minute lead accuracy. Typically leads are limited to 1mm for small diameters of the standard RV satellite series...
