ALL ITEMS ARE IN STOCK !
This includes the round body nuts in both Bronze and Steel as well as the Bronze Flanged nuts. Hex and square steel nuts are also ex-stock. We stock 3000mm lengths of screw.
Lead screws for medium to heavy duty industrial applications can be best supplied through our POWER SCREWS program. Complimented with a large selection of Bronze and Steel nut designs, the power screws can be supplied in lengths up to 6m on request. Bronze nuts are normally machined from SAE660 bronze but also employed aluminium bronze hybrids for certain applications. Primarily using the metric trapezoidal thread form in either a Carbon steel or 304 Stainless steel. The chart below details the stocked sizes at Abssac.

Key product advantages;
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)

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.
