1-11/16" 416 PSQ Stainless Steel Bar 121,000 (55MT)
Description: Pump shaft quality (PSQ) has historically been used for precision shaft in pumps. Now, there are many more applications that require these narrower diameter tolerances. The quality of the pump shaft (PSQ) has historically been used for the precision axis in the pumps. Now, there are many more applications that require these narrower diameter tolerances.
PSQ indicates turning, grinding and polishing shafts used in the rotating industries. The narrow diametric tolerance achieved by grinding reduces wear and provides a more constant product with controlled properties. This product is also straightened to provide minimal vibration over the entire shaft length.
