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.
