HIWIN rolled ballscrews can be classified into two grades:

• Precision rolled (PR)
• High Precision rolled (HP)

In general, both grades use the same preload method as precision ground ballscrews, except that there are some differences in the lead error definition and geometry tolerance.

• Accuracy (Precision)
• Accuracy (High Precision)
  
  
• Geometric Tolerance (Precision)
• Geometric Tolerance (High Precision)
  
  
• Category (Precision)
• Category (High Precision)

• FSW
• FSH

• FSI (DIN 69051 part 5 form B)
