Machine Tool Spindle Bearing Lubrication: What To Know
Spindle bearings must be properly lubricated to maintain a film of lubricant between the rolling elements and the bearing raceways. Without lubrication, the rolling elements will have direct contact with the raceways, and this will result in heat, race deterioration, rolling element deterioration, cage disintegration, and ultimately bearing/spindle failure.
There are several methods of lubrication used for spindles.
What Is the Spindle Repair Process?
The anatomy and functionality of a spindle is complex. And as such, it takes true expertise to understand, troubleshoot, and repair spindles correctly.
From the moment a spindle repair job hits the loading dock and repair line, a spindle repair company is entrusted with making the necessary adjustments and recommendations to ensure the spindle is returned in working order—and in some cases, in even better condition than before it ever showed sign of original malfunction.
However, though a spindle repair company may see thousands of repairs in any given year, each spindle repair job is different and must be treated carefully.
Top 4 Ways Your Spindle Rebuild Project WILL Benefit From an In-House Grinding Department
Simply put, a spindle repair company should have the experience and expertise to repair your spindle the right way. But short of sending your spindle to one company or another and hoping the repair goes well, how can you more accurately identify which shops are really the most skilled?

5 Key Reasons Why Your Spindle Repair Shop Should Offer a Spindle Support Program
After a spindle repair is complete, one of the best tools a repair shop can provide its customers with is a ‘spindle support program.’ This program should offer premium content with reports and recommended corrective actions for incoming spindles, as well as tips, tricks, and how-tos to keep a rebuilt spindle in proper working condition when it is returned to the customer.
Unfortunately, while support programs like these are commonplace in most industries, they are rare in the spindle repair business.

Walter DB112005 Spindle Repair
Our customer, a large tooling manufacturer, was experiencing a loud, roaring noise and poor part finish with this double-ended grinding spindle. Our evaluation of the spindle showed that one of the two pairs of ceramic bearings had failed due to contamination with grinding swarf. The grease in those bearings was degraded to a dry powder, providing little or no lubrication. We also determined that the wheel hub tapers on both sides had excessive runout.
