Available on 4mm to 15mm diameter rolled ball screw stock with 4mm to 20mm lead variants.

Abssac’s precision SR/SSR ball screws can be supplied in low Carbon Steel (SR) and stainless Steel (SSR) with lead accuracies of 0-20 Microns over 300mm. Each screw is complimented by a variety of recirculating ball nut designs to suit a multitude of duties.

Available on 4mm to 14mm diameter rolled ball screw stock with 1mm to 5mm lead variants.

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.

Available on 4mm to 14mm diameter rolled ball screw stock  with 1mm to 6mm lead variants.

This is our most compact nut design. Mounting is via external keyway offering the smallest nut diameter and length possible. This range of precision rolled ball screws operate just below the accuracy grades of ground ball screw assemblies. By using precision ground ball nuts and then pairing them with precision cold rolled ball screws, can provide lead accuracies of less than 52 microns of error 300mm.

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

Abssac is understood to be the first in the UK to supply a single piece, rolled ball screw that has a thread form right up to the end journal and a diameter that is equal or greater than that of the screw thread diameter. In the past, this format of screw and larger journal has only been possible by using a machined or ground screw thread form or by bonding a section of screw to a separate journal which would inevitably increase the unit cost.

Precision Rolled Ball Screws

Ball screws that have been cold rolled formed are ideal for applications that do not require the finite accuracy of the ground ball screw equivalents, but are still required to reliably transmit a linear load with high degree of accuracy. The following series are available in the precision rolled screw format.

SR/SSR with Flanged Mount Nut - C7 accuracy - 4mm diameter up to 15mm diameter screws. Screw leads from 1mm up to 20mm. Using the flange on the nut for attachment

MSR with Thread Mount nut - C7 accuracy - 4mm diameter up to 14mm diameter screws. Screw leads from 1mm up to 5mm. Using the thread on the nut for attachment

BSR Compact with Keyway Mount- C7 accuracy - 4mm diameter up to 14mm diameter screws. Screw leads from 1mm up to 6mm. Using external keyway on the nut  for attachment

PSRT with Flanged Mount Nut - C5toC7 accuracy - fixed 8mm diameter screw. Screw leads from 1mm and 2mm. Using the flange on the nut for attachment

SRT/SSRT with Flanged Nut - C7 accuracy - 4mm diameter up to 12mm diameter screws. Screw leads from 1mm up to 20mm. Using the flange on the nut for attachment

Put simply, the rolling process forms a thread for less cost than grinding. However, we can still achieve accuracies of C7-20 (that's 52 microns per 300mm of lead accuracy - 20 microns of axial backlash). We have well over 30 years of experience in ball screws, to help guide you through the selection process to ensure the right part is chosen for the application. In a nut shell, the rolled ball screw ranges encompass;

  • Precision rolled
  • Low cost
  • Lengths up to 1000mm
  • Precision C7-20 (New PSRT has 5 microns of backlash)
  • Lead accuracy .007mm/300mm or better
  • 4mm to 15mm diameter screws
  • Wide selection of leads and pitches available per diameter
  • Miniature precision ranges
  • Industrial heavy duty ranges
  • Flanged, cylindrical and end threaded ball nut designs
  • All parts can be supplied with journal ends machined and ready to fit application
  • All Ball screws can be supplied with integrated radial and thrust bearings mounts
  • ISO9001 approved

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


Linear guides and rails

If 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.

 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.


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.
