Lead screw (Precision)
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 2009. 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.
Precision Thread Rolling Service
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.

Lead screw (precision) MRH-A,B
The nuts are manufactured using a Polyamide type resin with excellent coefficient of friction properties. Ensuring a backlash free operation is made possible using a split nut and integral spring design. Please note that this product can be used without addtional lubircation as a lubricating agent is incorporated in the nut material.
Lead screw (precision) MRH-BP2
The nuts are manufactured using a Polyamide type resin with excellent coefficient of friction properties. Ensuring a backlash free operation is made possible using a split nut and integral spring design. The preload amount can be adjusted by changing spring specifications.
Lead screw (precision) R-MSS(Y)
Corresponding to a wide range of environment and having corrosion resistance, heat resistance. High Lead types (3times as diameter) are available.

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 diagrams below)
