Linear modules can realize linear and curved motion of the load through the combination of each unit. The linear modules that are currently widely used can be divided into two types: synchronous belt type and ball screw type.
The synchronous belt-type linear module mainly consists of: belts, linear guide rails , aluminum alloy profiles, couplings, motors, photoelectric switches, etc.
The working principle of the synchronous belt type is: the belt is installed on the transmission shaft on both sides of the linear module, and as a power input shaft, a slider is fixed on the belt to increase the workpiece of the equipment. When there is an input, the slider is moved by driving the belt. Usually, the synchronous belt-type linear module is designed to control the elasticity of the belt movement on one side, which facilitates the debugging of the equipment during the production process.
The synchronous belt linear module can be selected to increase the rigidity of the linear module according to different load needs. For linear modules of different specifications, the load upper limit is different. The accuracy of the synchronous belt linear module depends on the belt quality and the processing process in the combination, and the control of the power input will also affect its accuracy.

The ball screw type linear module mainly consists of: ball screw, linear guide rail, aluminum alloy profile, ball screw support seat, coupling, motor, photoelectric switch, etc.
1. Ball screw is an ideal product for converting slewing motion into linear motion, or converting linear motion into slewing motion. The ball screw consists of a screw, a nut and a ball. Its function is to convert rotational motion into linear motion.
2. Linear guide rails , also known as slide rails, linear guide rails, and linear slide rails, are used in straight reciprocating situations. They have a higher rated load than linear bearings and can bear a certain torque.
3. Aluminum alloy profile Aluminum alloy profile slide table has beautiful appearance, reasonable design, good rigidity and reliable performance. It is an ideal basic power component for combining machine tools and automatic lines . The slide table has high rigidity , low thermal deformation , and high feed stability , thus ensuring the actual accuracy under processing state (under load).
