The advantage of large journal at rolled screw cost

The advantage of large journal at rolled screw cost
Abssac reckons it may be the first company in the UK to supply a single piece, rolled ball screw that has a thread form right up to the end journal and a diameter that is equal or greater than that of the screw thread diameter. In the past, this format of screw and larger journal has only been possible by using a machined or ground screw thread form or by bonding a section of screw to a separate journal which would inevitably increase the unit cost.

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 is manufactured entirely from one piece of material. 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 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.
