Profile: THK America, Inc is a manufacturer of linear components and actuators. Our main product, the LM guide, is utilized for linear motion mechanisms in advanced mechatronics devices. The retainer-embedded roller guide, adopt a roller retainer to prevent the introduction of skew, realizing low-friction smooth motions. We offer heavy load ball screws with the caged ball structure (HBN model) to drastically improve the rated load compared to the conventional products. This is done by utilizing the optimum internal structure for use in heavy load condition.
