Our machining capability gives you a high journal concentricity product and can be applied to all screws regardless of diameter.
Lets work together to reduce your scrap rates and supply ball and leadscrew solutions that fit your application every time. We can work directly from your dimensional drawings or if they do not exist, why not supply us with a physical sample for us to copy. Although all types of end machine detail can be supplied we also offer a very cost effective basic end journal machining that fits our range of support bearings
Interestingly, a quick turnaround by Abssac has recently aided the restoration of two pre WW11 machine tools being restored to their former glory in a local woollen mills maintenance workshop. Despite the customer being without the original dimensional drawings for the ball screws and the fact that they were very much damaged, meant that Abssac had to rely on its extensive ball screw knowledge to satisfy the customer. First a careful measurement of the last remaining ball screw was undertaken. It was found that the ball screw was imperially sized, with a 1.00 inch diameter by 0.250 inch lead, Gothic arch ball screw format.
Abssac was able to utilise a cold rolled formed ball screw format, which were cut to a length and then machined at the ends to allow them to fit a thrust bearing to the whole assembly. The traditional square section nuts that were used by the old machines were replaced by adapted standard product range nuts and were chosen specifically for authenticity due to their single ball return design. The whole assembly was then low temperature black Chrome plated, which gave a corrosion resistant and exceptionally smooth and scratch resistant surface finish, hopefully giving the machine at least another 50 years of service.
Mr Phil Jones of Abssac says, “We have had great success in reverse engineering original designs of lead and ball screws where no formal drawing exists. Customers have shipped the parts for us to dimensionally check and copy into a new physical part. It is particularly nice to get involved with these types of project were we are part of a restoration. Abssac has a huge range of linear products, so nine times out of ten we can help with these more unusual requirements”
Linear guides and rails
If you are interested in the using the ball screw ranges, do not forget that we also supply the full range of linear guides and rails which can provide the load support in your linear mechanism. Offering excellent rigidity and parallelism during operation the guides can be used in both vertical and horizontal planes.

If you require further technical information, please do not hesitate to contact our sales engineers who will be more than happy to help you with your selection.
Greases and Lubricants
We provide a full range of quality, low cost lubricants for all our linear products including low vapour pressure greases for clean room and vacuum applications. For example the new Trigel line is specifically formulated to offer a lubrication solution for a wide range of linear motion applications. Please ask for further details. Grease features include, Temperature range -30°C to 150°C, Revolutionary multi-complex soap technology, Greatly extended lubrication intervals typically 3 times longer than conventional soap thickened greases. Good corrosion resistance. Some greases are supplied blue in colour for high visibility.
