G0704 Spindle Bearing Upgrade

Nachi Precision Tapered Roller Bearing Upgrade Kit

This offering is HIGHLY recommended for use with our G0704 Deluxe Spindle Drive kit.  This bearing kit is designed for 6000rpm max spindle speed when used with Kluber Isoflex NBU 15 spindle bearing grease (sold separately).  The kit consists of the spindle cartridge upper and lower tapered roller bearings to replace the low quality factory bearings which are failure prone at spindle speeds greater than 4k rpm.

Benefits of Nachi precision tapered roller bearings:

• Reliable 6k rpm spindle speeds for long part runs

• Significant improvement of spindle runout typically below 0.00015" TIR

• High Rigidity for smoother quieter cutting

• Improved surface finish on parts

• Excellent Longevity with proper break in and lubrication maintenance intervals
