ABB FSI series ball screws robots convert rotational into linear motion

The ABB FSI series ball screws are widely used in robots and have the following characteristics and parameters:

Basic Dimensions

Nominal Diameter: The series includes various nominal diameters, such as 14mm, 16mm, 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, and 80mm, to meet different load - bearing and installation space requirements.

Lead: Common lead values are 4mm, 5mm, 10mm, 20mm, etc. For example, the FSI1404-4 has a lead of 4mm, and the FSI1405-3 has a lead of 5mm. The lead affects the linear motion speed and positioning accuracy of the robot.

Nut Dimensions and Hole Spacing: Taking the FSI1605-3 as an example, the outer diameter of the nut is 30mm, the length is 49mm, the hole spacing is 10mm, and the overall size is relatively compact, which is convenient for installation and integration on the robot. Different models have different sizes to adapt to different robot structures and installation requirements.

Ball Diameter and Circulation Mode

Ball Diameter: The ball diameter varies according to different models. For example, the ball diameter of the FSI1404-4 is 2.381mm, and that of the FSI1405-3 is 3.175mm.

Circulation Mode: The FSI series usually adopts the internal circulation mode, which can save space and make the structure more compact. This design can make the balls circulate smoothly inside the nut, reducing friction and wear and improving the service life and efficiency of the ball screw.

Load-Bearing Capacity

Dynamic Rated Load: The dynamic rated load of the FSI series varies by model. For example, the FSI1404 - 4 is 875kgf, and the FSI1405-3 is 1013kgf. The dynamic rated load indicates the maximum load that the ball screw can withstand under dynamic conditions, ensuring reliable operation without excessive wear or deformation during the actual operation of the robot.

Static Rated Load: The static rated load also varies by model. For example, the static rated load of the FSI1404-4 is 1056kgf, and that of the FSI1405 - 3 is also 1056kgf. The static rated load represents the maximum load that the ball screw can bear when it is stationary or in a static state, which is an important parameter to consider when the robot is in a standby state or subjected to static external forces.
