MOST SIZES IN STOCK  - Rolled screw form using low cost Carbon Steel C45 – 1.0503 EN 10083-2 DIN103-7e

POWER Lead screws that are cold rolled formed have the immediate advantage of a work hardened surface on which the load bearing nut will travel. Starting with a pre-ground Carbon Steel bar stock, the thread form is gradually rolled into the material with increasing pressure ensuring precise material deformation along the thread form as it is worked. By repeating this process the screw stock work hardens into a smooth finish with the desired diameter and lead as the finished product.

Power Lead Screws

We stock up to 3000mm lengths of screw and all associated nuts

Abssac not only supplies high precision lead screws but also a range of medium to heavy duty industrial leadscrews. Continuously stocking up to 3 meter lengths of lead screw diameters of 12mm, 16mm, 20mm, 22mm, 24mm, 30mm, 36mm, 40mm and 50mm in both right and left handed formats. The POWER SCREWS are available in both Steel and Stainless Steel and can be supplied with a large selection of round bodied flanged or non-flanged Bronze matched thread nuts from stock.

Abssac can also supply the screws machined to print for easy connection to a range of in stock thrust and pillow block bearings as well as linear slides. Additionally, we supply weldable  square, hex and round steel nuts and Abssac is also offering a free cut to length service on all the screws.

Split Nut design works with complete confidence on Power Lead Screw

Another satisfied customer for Abssac required a more sophisticated nut design for use within a hot glue gun dispensing machine. By supplying a specifically designed bronze nut to match a 20mm diameter by 4mm lead trapezoidal power screw, the bronze nut was then meticulously separated into two working halves. When the two halves of the nut were brought together via a precision slide arrangement, also supplied by Abssac, the nut functioned in complete confidence as if it were whole.

The captivated nut which also allowed the mounting of a dispensing glue gun could then traverse the screw length as normal. The hot glue was accurately dispensed, but then at the end of travel the nut separated and returned quickly to the start position. This meant that the screw required only one direction of travel and reduced the cycle time for the glue head to return to the start position. To date many bespoke nut designs have been supplied, including optical mounts, cams, external threads, mounting holes, pulley grooves, tangs and linear guides to name a few. Lead screw sizes range from 1mm diameter up to 100mm with a wide range of both metric and imperial leads per diameter. Nuts can be manufactured in just about any machineable material including Bronze, steels and advanced plastics such as Delrin, PTFE or Turcite.

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 (see example diagrams below)
