Import Tips
• Verify dynamic/static load ratings and precision class (e.g
• C0-C3) in technical specs for correct subheading classification
• Include manufacturer test certificates showing ball recirculation mechanism to confirm as ball-type linear bearing
• Avoid misclassification as plain shaft bearings; provide CAD drawings illustrating rolling elements
