THK solved the problem, previously considered too difficult, of linear motion with rolling contact by applying its unique technological capabilities, and in 1972, it became the first company in the world to develop and commercialize the Linear Motion (LM) Guide. Our linear motion system enabled rapid improvements in the accuracy, speed and labor-saving potential of advanced mechatronic instruments.
THK has also developed many other unique mechanical components, including the Ball Spline, Ball Screws and Link Balls, which are manufactured by us for supply to customers worldwide.
Since 2019, THK has released a new IoT service called OMNIedge which enables predictive failure detection. The IoT is expanding throughout manufacturing at a rapid pace. Yet even as factories are in a hurry to implement this technology, many struggle with operational hurdles. THK offers an IoT service that gets to know your environment and works with you to overcome those barriers. We bring in our extensive know-how as a top manufacturer of machine components to help you achieve your IoT vision. It works by installing sensors on existing components to monitor their damage and lubrication status, then collecting data to analyze and provide alerts.
