Lead screw nuts eliminate backlash
Two new lead screw nut designs eliminate backlash, maintain a high axial stiffness and simultaneously reduce drag friction.
Eliminating backlash from lead screw nut designs has always been a demanding task To eliminate the backlash often meant a sacrifice in drag torque, but this is now a thing of the past

Remaining at the forefront of new technology associated with nut designs, Abssac is marketing two new nut designs that are at the leading edge linear nut design.
Using a revolutionary cross cam design, called the Active Cam, they eliminate the backlash, maintain a high axial stiffness but simultaneously reduce drag friction.
Normal split nut designs, with a loaded spring between the two nut halves, have inherently high drag torques and lower thresholds where axial stiffness can be maintained.
The new Active Cam units eliminate these problems, making them an ideal low cost replacement for ball screw assemblies.
In addition to this, the drag torque is bidirectionally stable resulting in higher positional accuracy in both directions, regardless of temperature variation.
Available to suit screw diameters from 6 to 16mm with a range of leads in each diameter, the new nut designs can be attached to the application via the integral flange mounted style nut XCF or by the thread mounted version XCT.
Finally the new designs automatically adjusts and compensates for wear during its duty cycle therefore maintaining features and benefits to system.
Simon Cattle, Managing Director of Abssac says: "There is a real demand for high accuracy rolled acme screws, but traditionally nut designs have trailed behind in terms of performance".
"These new nut designs bring a low cost alternative to the designer whilst maintaining a high degree of performance". Request a free brochure from Abssac ...
