Cost-effective linear motion for a wide range of applicationsigus, the leading manufacturer of plastic bearings and leadscrews, has developed a new spherical trapezoidal leadscrew nut, combining the technology of igubal self-aligning bearings with drylin leadscrew drives. This new leadscrew nut has a long life with no external lubrication required, and therefore enables reliable, precise and accurate linear motion.
The special triboplastic materials of the spherical ball and housing consist of high wear and dirt-resistant iglidur J and the tough and shock absorbent igumid G. The leadscrew nut provides high performance and has been designed to compensate for any manufacturing and installation tolerances which may occur. Typically drylin TR linear screw drives are produced from cold rolled steel, however VA stainless steel or hard anodised aluminium and a variety of thread profiles are available on request.
When selecting a linear drive solution it is recommended that both the flange bearing and leadscrew are supplied from a single supplier as both components have an equal influence on the operation and behaviour of the linear system.
