Cross roller bearings

Cross roller bearings from THK are the first choice when it comes to selection, accuracy, compact design and ease of use. Thanks to their clever 90° structure, they can absorb forces and torques from all four stress directions. The various types and shapes, together with their freely selectable accuracy classes, help to make planning connection constructions an easy and cost-effective process. THK cross roller bearings are used in a wide range of applications, including tooling machines, precision and medical devices, and especially in robots and handling systems.
