Available on 3mm to 15mm diameter screw stock with 0.5mm to 20mm lead variants. A precision ground ball screw series with repeatable accuracy of; C3 (zerobacklash) or C5 ( 5 micron maximum backlash). These screws have a fixed bearing end machined at one end of the screw. Abssac can delivery these ball screws quickly as the screw and jounal ends are stocked and ready to be machined to drawing specification. For more performance data, screw and nut dimensions please see our catalogue.

The BS series uses 3mm to 16mm diameter ground ball screw with 3mm to 6mm lead variants. This is our most compact nut design. Mounting is via external keyway offering the smallest nut diameter and length possible. Backlash can be eliminated. Using a compact cylindrical single nut, axial play can be eliminated using over sized balls. The BS series has a  with repeatable accuracy of  C3 (zerobacklash) or C5 ( 5 micron maximum backlash)

For more performance data, screw and nut dimensions please see our catalogue.

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.

Ideal for 4mm to 14mm diameter screws. The cylindrical type nut with metric thread at the nut end for ease of mounting. This design makes it particularly suitable for mounting within a cylinder keeping the overall diameter of the driven system to a minimum. The MS series is available with repeatable accuracy of  C3 (zerobacklash) or C5 (5 micron maximum backlash). For more performance data, as well  as further screw and nut dimensions please see our catalogue.

Available on 6mm to 10mm diameter screw stock with 1mm and 2mm lead variants. The square nut design has a large mounting face parallel to the nut centre. The nut design allows for easy mounting within applications where the flange attachment design might not be suitable. The KS series are available with repeatable accuracy of  C3 (zerobacklash) or C5 (5 micron maximum backlash). For more performance data, aswell as further screw and nut dimensions please see our catalogue.

Available on 4mm to 12mm diameter ground ball screw with 1mm and 2mm lead variants. The basic design has two ball nuts, a left hand and right hand thread all on one screw. This set up is often required to activate a precision gripping device or perhaps adjust the width of an area within a machine.

A recent application had this exact set up within a confectionary machine. Abssac supplied the SD1202-180L180R440C5 ground ball screw which utilises a 12mm diameter by 2mm lead ball screw in both a right hand and left hand format on the single screw.

Available on 6mm to 16mm diameter ground ball screw stock with 2mm to 5mm lead variants. A double nut/sleeve design with an intergral keyway slot within the nut housing for attachment purposes. The  two cylindrical nuts have predermined spacer inserted between them to apply a preload. The double nut design also enhances rigidity of the driven system.  Available with repeatable accuracy of  C3 (zerobacklash) or C5 (5 micron maximum backlash). For more performance data, aswell as further screw and nut dimensions please see our catalogue.

The FSBS series has a spacer  inserted between the two nuts to eliminate axial play. Pre-loading the axial force between two ball nuts can be applied to increase nut rigidity. This design uses a flanged nut in combination with a sleeve nut to enhance rigidity of the linear drive system. Using the bolt hole flange design makes mounting to the application quick and simple. The FSB series offers a set preload and competitive reliability. The end journals can be supplied machined to your drawing if required.

Ground Ballscrew

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.

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

Please do not forget to ask for our competitive support bearing prices !

If you require further technical information, please do not hesitate to contact our sales engineers who will be more than happy to help you with your selection.
