Haydon Kerk Motion Solutions Inc., a manufacturer of engineered linear motion products, offers the SAA06 motorized SplineRail linear actuator. Linear motion has traditionally required separate components to handle both drive and guidance. The compact SplineRail simplifies this by combining both functions in a single, coaxial component.

The Motorized SplineRail utilizes a Kerk precision rolled lead screw, supported by bearings, and contained within a concentric aluminum spline, driving an integrated Kerkite composite polymer nut/bushing. The extruded aluminum spline offers excellent torsional stability. KerKote TFE coating and self-lubricating Kerkite nut/bushing material ensure long life and zero maintenance. The motorized version of the SplineRail uses the Haydon Size 17 single stack or double stack stepper motor.

When mounted vertically, the SplineRail can also be used to simultaneously lift and rotate (Z-theta motion). With one motor driving the screw and a second rotating the rail, a compact, self-supporting pick and place mechanism can be created. Screw leads are available from 0.05 to 1.2 in. per revolution, providing a wide range of performance profiles, including self-locking threads that can support a load without external power or breaks. Haydon Kerk specializes in custom solutions and the SplineRail is a versatile platform to build upon.
