A micro pulley is a small, simple mechanical component that is widely used in various devices that require sliding or moving.
The working principle of a micro pulley is the same as that of an ordinary pulley, which mainly uses the rotation of the pulley to change direction or increase the magnitude of the force. It is generally composed of a wheel body, a wheel axle and a bearing, in which the wheel body is the main body of the pulley, the wheel axle supports the wheel body, and the bearing is a key component to support and reduce friction.
