Shigiya G30 Spindle Repair

Oil Bearing OD Grinding Spindle
The common cause of failure to these spindles is contamination in the lubricating oil. The contamination wears the shaft and bearing which eventually causes a breakdown in the oil film layer that supports the shaft. The radial and axial force that the shaft is subjected to during the grinding process causes the shaft to contact the ID of the bearing. The next step is spindle failure.
