Product Description
GD5008-3-268-300-C3--50mm Diameter Ball Screw

What is the "critical speed" of a ball screw?
The "critical speed" of a ball screw and nut refers to the rotational speed at which the ball screw is prone to catastrophic failure due to excessive deflection and vibration. For long-axis components like ball screws, gravitational force causes mid-span sagging. When the ballscrew kit rotates with both ends supported by bearings, this sagging (arch shape) intensifies with increasing speed. As the rotational speed rises, the arching amplifies until the ball screw fails, and this failure-threshold speed is defined as the critical speed.
?
Operating a ball screw pair beyond its critical speed leads to significant precision degradation of the entire machine due to severe vibrations. It is recommended to run all ball screws at 80% or lower of their critical speed. The critical speed can be enhanced by optimizing support configurations—for example, using ball screw support units with angular contact paired bearings at both ends. The selection of support bearings also plays a crucial role in improving the critical speed threshold.

It would be better if you sent the product drawing before you consult, no matter it is ball screw, Lead Screw, Linear Guide, ball spline or linear module.
