Lead screw (Precision)

Whether it is a simple lead screw, acme thread, ball screw or a complicated satellite roller screw, Abssac have one of the largest linear product ranges on the market. Combine this with a fast turnaround machine shop that can supply end journals that are ready to fit directly into your application. Abssac is ready to help you find the right product for the right price.

Employing a traditional hands on approach to business, Abssac has long been associated with linear technology and in 2008 is expanding its range further by adding more diameters and lead per product. Abssac offers a vast range of lead screw sizes range from a miniature 4mm diameter up to 200mm with a wide range of both metric and imperial leads per diameter. Supplying, cold rolled, whirled, machined or ground style lead screw formats in stainless steel, low carbon steel and exotic materials if required.

If you require multi-start, high helix for high linear traversing speeds or ultra fine Vee thread format screw for positional accuracy Abssac can supply all of your linear requirements.

All our antibacklash nut designs compliment the complete range of lead screws and in some cases can be tapped to run on ball screw threads. Primarily Abssac uses Delrin as the base material for the plastic nuts. Delrin is an acetal resin engineering plastic and is often used as a metal substitute. Delrin is lightweight, has a low coefficient of friction, is extremely wear-resistant and capable of operating in temperatures in excess of 90 degrees Celsius (approx 200 degrees Fahrenheit). Other plastic materials we use are: polyoxymethylene (POM), acetal resin, polytrioxane and polyformaldehyde. Bronze nuts are normally machined from SAE660 bronze but also employed aluminium bronze hybrids for certain applications.

A truly extensive range of leadscrews are available to you. We supply both acme, vee form and trapezoidal thread forms that are precision rolled to produce a worked hardened finish. Available in a wide choice of coarse to fine pitch threads on each diameter, ensures that we have the product choice to exactly fit your application parameters. Our lead screws can also be supplied in both a right hand and left hand thread format to provide matched pairs if required. Available in both metric and imperial formats they are easily combined with some of the most advanced antibacklash nut designs available and can be supplied in either standard bar stock format or cut to the length you require. Additionally, we have the capability to machine journal end detail to your drawing specification, reducing your scrap rates and allowing us to supply a ready to fit product every time.
