Whether it is a simple lead screw or acme thread, Abssac has one of the largest linear product ranges to choose from. Combine this with a fast turnaround machine shop that can supply end journals that are ready to fit directly into your application, which ultimately reduces your scrap rate. Abssac is ready to help you find the right product for the right price.
Employing a traditional hands on approach to business, Abssac has expanded its lead screw ranges further by adding more diameters and leads per product range in 2014. We now supply miniature diameters from 2mm up to the power screw ranges that start at 12mm and go up to a maximum of 200mm in diameter . We supply both metric and imperial leads per diameter in both right and left hand formats. Supplying, cold rolled, whirled, machined or ground style lead screw formats in stainless steel, low carbon steel and exotic materials if required, means that we have the linear device to suit all applications.
If our standard thread styles and forms do not quite fit what you are looking for, we can provide a thread form to your exact specification. We also stock a wide variety of thread forms and sizes. The engineering department welcome inquiries for special and exotic thread forms and places us in the unique position to research and develop custom thread forms and provide first article inspection if required.
Quick delivery, competitive pricing and a knowledgeable sales team add to the whole product package.
Abssac supplies both machined and rolled thread formats. Lead screws that are cold rolled formed have the immediate advantage of a work hardened surface on which the load bearing nut will travel. Starting with a pre-ground bar stock, the thread form is gradually rolled into the material with increasing pressure ensuring precise material deformation along the thread form as it is worked. By repeating this process the screw stock work hardens into a smooth, polished like finish with the desired diameter and lead as the finished product.
The smooth acme screw provides a high efficiency, drag reducing surface which is ideal for the range of associated plastic and bronze nuts. In particular, the revolutionary active cam nut which handles loads above the normal ratings of a normal plastic nut without loss of it’s antibacklash features works exceptionally well with this product. Supplied in stainless steel to a precision lead accuracy or as it is sometimes termed, pitch error, of 0.05mm per 300mm of linear travel means that the leadscrews can be reliably used within high accuracy linear applications. Primarily supplying acme or trapezoidal thread formats via this process the Abssac precision lead screw product is winning business through its high efficiency product finish and competitive pricing structure.

End Journal machining
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 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 offer a very cost effective basic end journal machining that fits our range of support bearings (see example diagram below)
