Nut models: LPFT, LSFT
Unit: mm

Remarks
1. We recommend NSK support unit WBK25-01 (square type, fixed side), and WBK25S-01 (square type, simple support
side), and WBK25-11 (round type, fixed side).
2. NSK grease LR3 is recommended. The amount for replenishing should be about 50% of the nut internal space
capacity.
3. Permissible rotational speed is determined by a d • n value and a critical speed. See page B509.
