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...

The new “ABFT” nut design is for lighter load OEM applications where smooth movement and low drag torque for axial loads up to  4.5kg are required. The main body of the nut utilises the latest technology in injection moulding techniques to produce the structural strength.

The first patent for a roller screw was recorded in 1949 by the inventor Mr Bruno Standgren Carl, which was an adaptation of a frictionless bearing design patented back in 1939 by Mr Oscar and Stewart  McCurdy.

Abssac’s standard and precision http://www.abssac.co.uk/c/Linear+Products/1/ can be supplied in Stainless Steel and low Carbon Steel with lead accuracies of 0-20 Microns over 300mm. Our precision ball screws have operational tolerances comparable to more expensive ground ball screw assemblies, but at much less cost.

Abssac is well known for its quality power screws ranging from about 16mm up to 200mm in diameter, but an often little known side of the company is its capability to supply precision miniature cold rolled formed lead screws and nuts.

Are you looking for a lead screw supplier that can produce exactly what you want ? Or perhaps you have an old acme screw that needs replacing but have no technical drawing specifications to work from.  Abssac can help.
