Let’s work together to reduce your scrap rates and supply leadscrew solutions that fit directly into your application, every time.  With a machining capability that is enjoyed by numerous ABSSAC customers the company provides an excellent journal concentricity product, regardless of diameter. ABSSAC can work directly from dimensional drawings or if they do not exist, they accept the physical sample for them to reverse engineer. Although all types of end machine detail can be employed ABSSAC offers a very competitive basic end journal machining that fits their range of support bearings

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 great to get involved with these types of projects where 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”

ABSSAC also supplies a full range of linear guides and rails which can provide the load support to a linear mechanism. Offering excellent rigidity and parallelism during operation the guides can be used in both vertical and horizontal planes. The whole program allows ABSSAC to supply a complete linear system, which they will assemble for you as well if required. Should you require further technical information, please do not hesitate to contact ABSSAC sales engineers who will be more than happy to help you with your selection.

ABSSAC is also constantly investigating ways in which linear solutions are made more affordable. One method has been to employ plastic moulding injection techniques for the lead screw nut bodies. Then instead of machining the lead screw form , they have utilised cold rolling precision methods. Both methods significantly reduce unit cost and as shown in the image has no detriment to form and function. The lead screw shown below is a cold rolled formed 7 start, Stainless Steel screw with a lead accuracy of  .25mm per 300mm of travel. (14TPI .250inch diameter .500inch lead).  If you currently use lead screw and nut combinations in your application why not set ABSSAC the challenge to prove their affordable solutions.
