Remarks
1,For the lubricating oil,SKF-LGMT2 is designated,others aren't allowed
2,if "A" is behind the center model name,it denotes a draw-off nut attached.
3,About radial force data, please refer to workpiece weight and machining force.
4,if "A" is behind the center interchangeable tip name,it denotes the tip is extended length.
5,About axial force data, please refer to the hydraulic pressure data of the tailstock.
6,For live centers, SKF lubricating oil is designated, it is waterproof.
7,Customized order can be accepted.
8,Subject to technical changes.
