Nut models: PFT
Unit: mm

Remarks
1. We recommend NSK support unit WBK15-01A (square type, fixed side), WBK15S-01 (square type, simple support
side), and WBK15-11 (round type, fixed side).
2. Only rust preventive agent is applied at time of delivery. Please apply lubricant (oil or grease) before use.
3. Permissible rotational speed is determined by a d • n value and a critical speed. See page B509.
