for Oilfield & High-Strength Rotating Applications
Aamor Inox manufactures premium-quality 17-4PH / 1.4542 Shafting stainless steel bars for demanding Oil & Gas, pump, valve, fluid-control, and precision rotating-equipment industries requiring exceptional shaft stability, dimensional integrity, and dependable long-term mechanical performance.
directly influence equipment performance
At Aamor Inox, Pump Shaft Quality bars are engineered as precision rotating components where running accuracy, dimensional stability, and rotational consistency directly influence long-term equipment performance.
Developed specifically for demanding rotating-equipment applications.
For precision rotating systems, ovality and out-of-roundness control become important for maintaining dependable shaft performance and long-term operational stability.
Aamor Inox is India’s largest producer of Shafting bars.
Our PSQ Bars are more than 8 times straighter than industry standards (ASTM A108), with straightness readings of 0.0015” T.I.R per ft max (up to 0.25 mm / meter). Tight diametrical tolerance achieved through grinding reduces wear, improves roundness consistency, and minimizes vibration throughout the shaft length.
