Ground Ballscrew

Ball screws that have been formed by a grinding process are used where acute linear accuracy is paramount within an application. We offer a quality program of metric threaded screws, with a variety of standard and bespoke ball nut designs. Diameters from 1.8mm to 16mm and leads of 0.5mm to 30mm are available with accuracies of C0 to C5. All ground ball screws can be supplied cut to length, with end journals machined ready to fit into an application.

Ball screws that have been formed by a grinding process are used where acute linear accuracy is paramount within the application. We offer a quality program of metric threaded screws, with a variety of ball nut combinations. The following series are available in the ground screw format.

SG Compact Flange Mount Nut - C3 or C5 accuracy - 3mm diameter up to 15mm diameter screws. Screw leads from 1mm up to 12mm. Using the flange on the nut for attachment

BS Compact Ball screw -C3 or C5 accuracy - 3mm diameter up to 16mm diameter screws. Screw leads from 1mm up to 5mm. Using external keyway on the nut  for attachment

FBS FKB FDB FEB Flanged Mount- C3 or C5 accuracy - 1.8mm diameter up to 20mm diameter screws. Screw leads from 0.5mm up to 20mm. Using the flange on the nut for attachment

MS Thread Mounted - C3 or C5 accuracy - 4mm diameter up to 14mm diameter screws. Screw leads from 1mm up to 5mm. Using the thread on the nut for attachment

KS Square Nut - C3 or C5 accuracy - 6mm diameter up to 10mm diameter screws. Screw leads from 1mm up to 12mm. Using flat predrilled area of the nut for attachment

SD Bidrectional -  C3 or C5 accuracy - 4mm diameter up to 12mm diameter screws. Screw leads from 1mm up to 12mm. Using flange on the nut for attachment

SWBS Compact  - C3 or C5 accuracy - 6mm diameter up to 16mm diameter screws. Screw leads from 2mm up to 5mm. Using external keyway on the nut  for attachment

FSBS Double nut Flanged - C3 or C5 accuracy - 6mm diameter up to 16mm diameter screws. Screw leads from 2mm up to 5mm. Using flange on the nut for attachment

C3 accuracy = Zero-Backlash

C5 accuracy = 5 microns max backlash

In March 2008 we launched a new end deflection series, which recirculates the ball bearings in the end plate of the ball nut. This design not only reduces the length of the ball nut but reduces the cost as well. The new FEB and FDB series are available in diameters of 6, 8, 10 and 12mm with leads ranging from 2.5 to 10mm. As standard this new series offers up to C3 lead accuracy and a full end machining capability.

Please also note that we offer the capability to supply customs designs to suit the application.

Linear guides and rails

Linear guides and railsIf you are interested in the using the transport 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.

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


Thrust and radial bearings

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.
