Suitable for cleanroom environments, the CGL15N/CGL20N Actuator has a clean, corrosion resistant, and longterm maintenance-free design. For low particle generation, it features a seal mechanism and a full size cover. AFE-CA grease (designed for cleanrooms) is also used to reduce dust. The actuator's ball screw and LM guide are treated for high corrosion resistance. It employs a synthetic resin cage with a patented curvature that cradles each ball and separates it from the next one. The spaces between the rolling elements retain grease and act as a lubrication system. Provides low dust generation and high-speed capabilities. It is compliant with ISO 14644-1 Class 4 (equivalent to FED209D Class 10) at 2,000 [mm/s].
