Power Lead Screws

POWER Leadscrews are an excellent and reliable way of converting rotary motion into a linear motion. Application criteria such as  speed, load and the accuracy of position all have a direct effect on the form and physical size of the lead screw and nut design. If you use leadscrews and nuts or perhaps you are considering the product within your designs, then give ABSSAC a call. We stock lead screws for industrial through to precision applications and have knowledgeable sales staff on hand to help with your selection. ABSSAC offers a complete turn key machining options on all of the screws and nuts as well a full range of radial or thrust bearing units, which can be supplied at very competitive prices.

The POWER screw lead screws primarily use a trapezoidal thread form that delivers high performance and repeatability. Stocking up to 3 meter lengths of lead screw in diameters of 12mm, 16mm, 20mm, 22mm, 24mm, 30mm, 36mm, 40mm and 50mm in both right and left handed formats. Supplied in both Steel and Stainless Steel the POWER SCREW lead screws ranges are complimented by a range of flanged or non flanged Bronze nuts as well as round, hex and square steel nuts. ABSSAC offers a free cut to length service on all the POWER SCREWS.

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 Stainless 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. The Trapezoidal screw form deliverers a high efficiency, drag reducing surface which is ideal for the range of associated plastic and bronze nuts; Abssac's TR316 POWER lead screw product is winning business through its high efficiency product finish and competitive pricing structure.

Position accuracy - Tolerance is +/- 0.2 mm for every 300 mm of the thread. Available lengths - Stock lengths 3000mm or shorter

 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.

Full End Machining is available

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  leadscrew solutions that fit your application every time.
