NSK Cartridge Spindle For NC Lathes

Types and Features

• SH3000NW (SH3060NW, SH3080NW) Type
• Most suited to low speed, heavy cutting

This type uses two tapered roller bearings and one angular contact ball bearing.  The preload of the tapered roller bearings is adjusted by rotating the round nut mounted on the rear of the spindle. The angular contact ball bearing is spring preloaded, thus the main spindle shaft is supported at 3 points.
 

• JSH 1000NW (JSH 1045NW, JSH 1060NW, JSH 1080NW) Type
• Most suited to light-load, high-speed cutting

This type uses two ultra-precise angular contact ball bearings on each end.  The preload is adjusted by inserting spacers between the bearings.
