ABB FSU2005 FSU series ball screws robots convert rotational into linear motion

The ABB FSU series is a type of ball screw used in robots, featuring high precision, high efficiency, compact design, and high rigidity and stability. It is produced by ABB's partner manufacturers. 

Here is a detailed introduction:

Characteristics

High precision: The FSU series ball screws adopt a precision manufacturing process, which can achieve precise linear motion positioning with micron-level positioning accuracy. This high-precision performance enables robots to accurately complete various operations in tasks such as electronic component assembly and precision part processing, meeting the high-precision requirements of robot applications.

High efficiency: With a small rolling friction coefficient, the FSU series can efficiently convert rotational motion into linear motion, effectively reducing energy consumption. This not only makes robots more energy - efficient during operation but also improves their motion speed and response performance, enhancing the overall operational efficiency of robots.

Compact design: The single - nut internal circulation structure of the FSU series results in a relatively small overall size, occupying less space. This makes it suitable for installation in the joints and linear motion mechanisms of robots where space is limited, facilitating the optimization of the robot's structural design and improving space utilization.

High rigidity and stability: The screw and nut of the FSU series are made of high-strength materials and undergo special heat treatment and surface treatment, which endows them with high rigidity and deformation resistance. They can withstand large loads and impact forces, ensuring the stability and reliability of the robot during motion and enabling the robot to maintain accurate motion trajectories and posture under various working conditions.

Models of ABB FSU series

FSU1605: The screw diameter is 16mm, and the lead is 5mm. It has a relatively small size and is suitable for some robot joint structures that require a small installation space and have certain requirements for motion accuracy.

FSU2005: The screw diameter is 20mm, and the lead is 5mm. It has a moderate load - bearing capacity and accuracy level, which can meet the general - purpose motion control requirements of most robots.

FSU2505: The screw diameter is 25mm, and the lead is 5mm. This model has higher rigidity and load - carrying capacity, which is suitable for robots that need to bear a certain load during operation, such as some industrial robots for material handling.

FSU3205: The screw diameter is 32mm, and the lead is 5mm. It has better high - speed performance and can maintain stable operation at higher speeds, which is suitable for applications where robots require high - speed motion.

FSU3210: The screw diameter is 32mm, and the lead is 10mm. It has a larger lead, which can make the robot achieve a larger linear displacement in a single rotation, improving the motion efficiency of the robot. It is often used in robot linear motion modules with longer stroke requirements.

FSU5010: The screw diameter is 50mm, and the lead is 10mm. This model has a large load - bearing capacity and high rigidity, which can meet the needs of heavy - duty robots for precise motion control.
