Precision miniature cold rolled lead screws and nuts can be found in a multitude of applications where typically the rotation of a motor is translated into a linear motion via threaded nut that matches the thread form of the screw. Cold rolled threads offer great precision and surface finish at competitive prices.Whether it is a single start or multi helix thread form, pitch error of the thread can be maintained to a precision classification of 0.07mm/300mm. When using a machined thread, a pitch accuracy tolerance of 0.05mm/300mm can be achieved. Miniature lead screws can be supplied in both Steel and Stainless Steel and in some occasions in Aluminium and Plastics.
Miniature lead screw applications require smooth operation and low frictional drag due to physically smaller drives with torque limitations. Ensuring the fit between the nut and screw threads is of paramount importance as any small errors in these areas can lead to torque spikes during operation.Integration of the nut to the physical application can be via a simple thread mount or integral flange, however the engineers at ABSSAC are more than happy to help incorporate tangs, levers, trunnions etc. to make the final part even more multifunctional.Add to the package that end machining of the screws and the nut production is machined and completed at ABSSAC in the United Kingdom, means quick turnaround all carried out be trained and by knowledgeable people. ABSSAC is a ISO9001 and JOSCAR approved company.
The next time you have a miniature application that requires the translation of rotary input to linear output then perhaps give ABSSAC a call. Tel 01386 421005
