Continuously stocking up to 3 meter lengths of trapezoidal lead screw diameters of:
12mm, 16mm, 20mm, 22mm, 24mm, 30mm, 36mm, 40mm and 50mm in both right and left handed formats, the screws are complimented by a large selection of industry standard Bronze and Steel nut designs. The screws are available in both Steel and Stainless Steel, with a large selection of round bodied flanged or non-flanged Bronze nuts from stock. Additionally, weldable square, hex and round steel nuts are available. ABSSAC’s capability as a trusted supplier is enhanced by the options to supply cut to length or ready to fit, machined bearing journal ends to the screws. Quality assured screws and nut combinations can be fitted directly into the customer’s application without further intervention. ABSSAC is also able to offer gun drilling, screw hardening and special coating treatments.
WHEN IT COMES TO LEAD SCREWS FOR MEDIUM TO HEAVY DUTY INDUSTRIAL APPLICATIONS, ABSSAC WORKS HARD TO KEEP THE CUSTOMER HAPPY.
Recently ABSSAC was approached to help specify a nut and screw combination within a redesigned food packaging machine. The original application used both a left hand and right hand opposing screw to operate a high speed gripper in a machine that hot plastic foil sealed ready to cook meals for a leading supermarket. The application dictated there could be no lubrication within the system, which contributed to the premature failure of a competitors plastic nuts after only 50,000 cycles. The existing set up also suffered from excessive positional lead error which added a drag load and excessive wear of the nuts, due to binding. ABSSAC’s engineers set about utilizing a PTFE impregnated plastic as the anti backlash nut material and then picked matched pitch accuracy screws in both the right handed and the left handed screws to ensure linear positional accuracy. This winning combination was proven by initial tests cycles, which achieved over 56,000 cycles without any detrimental sign of wear to the nuts. Mr. Phil Jones, of Abssac who has over 20 years lead screw experience states, "By being able to match the screws and nut pitch accuracy reduces the stresses within the system considerably ensuring a more reliable linear movement”.
90MM DIAMETER SCREWS DELIVERED TO WATER FILTRATION PLANT
Using an existing damaged screw for dimensional information, ABSSAC replicated 14 screws which were a massive 90mm diameter by 2 metres long. Weighing over 100kg each and using a basic trapezoidal thread form satisfied another ABSSAC customer.
