Import Tips
• Include gear mesh pattern documentation and AGMA quality class (typically Q12 or better)
• Certify non-destructive testing (NDT) results like magnetic particle inspection for surface defects
• Avoid misclassification as shaft coupling (8483.60) by documenting internal gearbox positioning
