Ball screw (* NEW *)

A Technological breakthrough..

Rolled Ball screw has larger end journal diameter using one piece of material !

Abssac is understood to be the first in the UK to supply a single piece, rolled ball screw that has a thread form right up to the end journal, which then has a diameter that is equal or greater than that of the screw thread diameter itself.

At first glance this innovation seems simple, but when you start to consider the limitations in thread rolling processes and take into account that previously it has been impossible to roll a thread on anything other than a single diameter bar stock, for the entire length of the screw, you start to see the great technological advance.

A rolled ball screw will always be more competitively priced than a ground screw equivalent and this has always caused the immiscible dilemma to the design engineer. Use a machined or ground screw to get the larger journal for greater axial thrust attachment security and available bearing choice or sacrifice the larger journal advantage for the less cost rolled screw.

The new SRT ball screw series, available from Abssac, are manufactured entirely from one piece of material and for the first time make the miscible supply.
By providing a high linear accuracy, the new ball screw series allows the customer to replace expensive ground ball screws with a rolled screw alternative at less cost and with operational confidence. As standard, two precision tolerances are available ; C7-20 (0.05mm/300mm, 20 microns axial play)  or  C10-50 (0.2mm/300mm, 50 microns axial play).

As standard the new series is available in  SCM415H hardened tool steel (HRC58/62) or 440C hardened Stainless Steel (HRC55+) . With all the ball screw sizes, a range of flanged, cylindrical and end threaded ball nut design mean that connection to any linear device is made simple.

Larger end journals also allow for much faster delivery due to unfinished end journal stock.
