PBC Linear has revolutionized traditional machining with the patent pending SIMO (Simultaneous Integral Milling Operation) process. The SIMO process uses synchronized cutters, eliminating built-in extrusion variances by machining all critical edges concurrently, in one pass. This ensures tight tolerances, limited variance, and a remarkably straight and repeatable surface.

SIMO actuators are built on either a low profile or tall base rail with configurable bearing and drive options that can be tailored to exceed performance requirements.
