Available on an 8mm diameter rolled ball screw stock with either a 1mm or 2mm lead variant.


Our precision ball screws have operational tolerances comparable to more expensive ground ball screw assemblies, but at much less cost. Using precision ground ballnuts running on precision rolled screws, means that our lead accuracy is close to precision ground screws. All products are backed up with a quality assurance of ISO9002 and of course Abssac’s 30 years of ball screw experience. The standard ball screw products are available in non machined end form, or machined to specific end detail requirements. A full machining capability provides a service for complete end journal completion to the highest accuracy. The parts can be delivered in short lead times ready to fit.

Offering a maximum of  5 micron backlash, which is normally only avaialble with ground balls screws. 2D and 3D CAD files upon request. Abssac’s standard and precision ball screws can be supplied in Stainless Steel and low Carbon Steel with lead accuracies of 0-20 Microns over 300mm. The product range also includes flanges, pillow block bearings and synthetic greases.

If you are retrofitting or specifying ball screws within an application then please give us a call.  We have the knowledge and product range to help choose the right part and most importantly within budget. For more performance data, aswell as further screw and nut dimensions please see our catalogue.

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.
