SplineRail Linear Actuator Simplifies Drive and Guidance

Haydon Kerk Motion Solutions, Inc., a manufacturer of engineered linear motion products, recently introduced 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" 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.

Typical applications include pick-and-place mechanisms and robotic assemblies in life sciences instrumentation, semiconductor equipment, business machines, packaging and assembly and a wide range of factory automation applications. Combined with Haydon Kerk's motion control components, the SplineRail can be used to create custom systems for many types of motion. High reliability without the need for maintenance or adjustment makes the SplineRail well suited to the demands of industry.
