This kinds of Crossed roller bearings usually used for robots arm 

  A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement.The links of the manipulator can be considered to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand. However, the term "robotic hand" as a synonym of the robotic arm is often proscribed.
  At present, most of the robots used in the industry are based on the type of mechanical arms, and the mechanical arms are different in various shapes and sizes. Common types include linear arms, SCARA arms, joint multi-axis mechanical arms, etc.  In terms of joint structure, it can be divided into two categories: three-axis (inclusive) or less (three-axis for short) and four-axis (inclusive) or more (multi-axis for short).
