Available from 1.8mm to 20mm diameter using a ground ball screw stock. It is our most simple flange mountable single nut ball screw design. It is possible to supply the FBS series with slightly over sized balls to eliminate axial play and provide a light preload. The nut should be mounted using bolt holes in Flange.This series are available with repeatable accuracy of C3 (zero backlash) or C5 (5 micron maximum backlash). There are four types of nut design which have been designed to save space.

It is through this series (FBS); that Abssac is supplying what is believed to be the world’s smallest precision tolerance ball screw and nut assembly. With an amazing screw diameter of only 1.8mm and a lead of 0.5mm the new miniature ball screw range is ideally suited to the ever-smaller requirements of medical, optical and military application requirements. Using a ground screw format the carbuerised steel ball screw is supplied complete with journal ends machined to suit standard radial block bearings. A standard a 6mm diameter nut body is used to house the 0.4mm diameter ball bearings, which are captivated in a recirculating ball nut design. Remarkably, the new product range offers a C3-05 accuracy grade ( i.e. 0.005mm axial play). Fixing the nut to the application is made simple by a range of flange sizes.
For more performance data, screw and nut dimensions please see our catalogue.
If you are interested in the using the ball screw ranges, do not forget that we also supply the full range of linear guides and rails which can provide the load support in your linear mechanism. Offering excellent rigidity and parallelism during operation the guides can be used in both vertical and horizontal planes.

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.
