NSFU/NSFNUR Right Hand Screw Nut
High-precision NSFU/NSFNUR right hand screw nut for ball screws, offering low friction, high load capacity, and reliable linear motion for CNC and automation.
This series of nuts adopts a right-hand thread design, which means that linear motion is generated when rotating in a clockwise direction, which conforms to the standard transmission habits of most machines.

Internal Circulation
The circulation mode of the right hand thread nut can be divided into internal circulation, external circulation, end plug circulation, etc. according to the circulation mode of the steel ball. Each circulation mode has different advantages and disadvantages and can be selected according to needs.
| Circulation Method | Specifications | Features | |
| Single Nut | Double Nut | ||
| Internal circulation | NSFU | NDFU | The nut has a small outer circle (does not take up space), suitable for small lead |
| External Circulation | NSFV | NDFV | Economical series, suitable for large lead and heavy load |
