ML MINIATURE LINEAR ACTUATOR PATENT PENDING - Patent Pending Machining Process - High Precision Mounting Surfaces - Tight Tolerances ± 0.025mm (0.001 in) PBC Linear has revolutionized traditional machining with the patent pending SIMO™ (Simultaneous Integral Milling Operation). The typical aluminum extrusion process produces a natural bow, twist and variance. Costly straightening and aligning is traditionally used to combat this variance, resulting in a semi-straight aluminum extrusion that drives the cost up. PBC’s SIMO process uses synchronized cutters, eliminating built-in extrusion variances...

ML MINIATURE LINEAR ACTUATOR Multi-Axis Mounting ML actuators are designed to perform well in XY and other Cartesian arrangements. The actuator body forms a strong beam with higher moment loading capacity. Special dovetail slots on all sides allow the actuators to be mounted on their bottom surface or on either side. Carriage brackets and special wedge mounting clamps allow for precise and rigid mounting arrangements. Linear guides can be installed on one or both sides of the actuator with one or two runner blocks on each rail for greater rigidity in gantry applications. Multi-axis gantries can...

LINEAR ACTUATOR TECHNOLOGY The ML miniature actuator has surpassed expectations and left the competition in the dust. Its combination of compactness and (60 lbf) 265 N pound thrust power gives this actuator an edge for automation applications where space is critical. Plus, the SIMO™ machined rail surface and zero backlash lead screw assembly ensures accuracy and precision for syringe pump and optical control applications.

ML MINIATURE LINEAR ACTUATOR Performance Data The load rating and system speed must both be accounted for when sizing a lead screw system. The nut threads and screw threads form a plane bearing system. The PV limit of a polymer material is the point at which friction-generated heat can no longer be expelled at a rate to prevent the material from overheating. Such overheating while under stress can cause permanent deformation of the material. Ignoring how the system’s speed and loading relate to the nut material’s PV rating can lead to dramatically shorter thread life. The primary modes of failure...
