Precision recirculating ball screw range
The low friction within ball screw designs means that a high mechanical efficiency is delivered compared to that of lead screw designs. A typical ball screw may be 90 percent efficient, versus 30 percent efficiency of a lead screw of equal size. Ball screw specification is often a result of an applications requirement to have smooth...

POWER LEAD SCREWS @abssac
Lead screw and nut combinations are often chosen from standard ranges to convert the rotary motion of the screw into a linear movement. However sometimes the nut design can be adapted to deliver more than one advantage. One big advantage is that nuts can be manufactured in just about any machineable material including bronze...

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.
