How to Choose the Right Linear Module: Belt Drive vs. Ball Screw?

Timing Belt：

• High velocity

• Low initial costs

• Mechanically simple

     Although belt drive applications can reach a high velocity and are not expensive, they have limited accuracy and acceleration, Slipping and stretching of the belt causes a less precise system which requires more maintenaice. The operating efficiency of the belt is affected by the heat originated from the mechanical contact and slip.

    Ball screw driven applications are well-known for having high efficiency and decent accuracy

• High force possible

• Decent accuracy
  

    But their low acceleration limits the dynamic possibilities.Large ball screw applications suffer from screw whip when they rotate at high velocity. Both velocity and length increase the whip effect. This means you need to find the right balance as you cannot have high velocity over long distances. 

• Belt Drive: Best for high speed (up to 2m/s), long stroke, and economical cost. Ideal for packaging and pick-and-place.

• Ball Screw: Best for high precision (±0.01mm), high rigidity, and vertical heavy loads. Ideal for CNC and semiconductor equipment.
