THK’s new Type GL-N Actuator combines newly engineered enhancements and Caged Technology to allow a lifecycle increase of 8 times as well as exceptionally smooth and precise movement. Caged Technology employs a synthetic resin cage with a patented curvature that cradles each ball and separates it from the next. The spaces between the rolling elements retain grease and act as a lubrication system for long-term, maintenance-free operation. Without metal-to-metal contact, the Type GL-N can reach speeds up to 2 times faster than conventional types (at 5 m/sec, and accelerations over 5Gs), according to the company. Using not one, but two caged ball type LM guides, the new design results in load capacities 200 percent greater than that of THK’s original Type GL. The Type GL-N is equipped with industry-standard motor mounts for easy integration. Metric mounting holes are standard and inch mounting holes are available upon request at no additional cost. The Type GL-N standard lengths reach 3m and custom lengths are available. THK America Inc. Booth 14029
