ScrewRail Precision Rolled Lead Screw

The ScrewRail is now offered in an updated version that combines drive and support/guidance components in a single, compact, coaxial design. By eliminating the need for external rail-to-screw alignment, the ScrewRail simplifies the design, manufacturing and assembly of motion systems.
The ScrewRail’s coaxial design saves as much as 80% of the space used by a two-rail system. The ScrewRail is a precision rolled lead screw, supported by sealed bearings and contained within a concentric steel guide rail, which drives an integrated nut/bushing. Because all alignment requirements are achieved within the ScrewRail, support and positioning are much less critical than with traditional slide assemblies. Kerkote TFE coating and self-lubricating nut/bushing materials ensure long life without maintenance. It has also recently been upgraded with a metal-reinforced bushing, providing increased strength and stability.
