NSK recently solved an issue with recurring spindle bearing failures in four CNC machining centers at an automotive industry supplier's factory, saving the facility €32,880 per year after identifying the root cause of spindle bearing failures every two weeks.

To investigate the root cause behind the failure, NSK requested an investigation into the entire application and maintenance process. An expert from NSK observed the maintenance department's installation methods and found that the main problem was improper installation of the super-precision angular contact ball bearings.

The correct installation of bearings is crucial for the optimal operation and continued working of industrial machinery. In this regard, correct training and the use of appropriate tools are particularly important. With this in mind, NSK has launched a comprehensive program for the company’s maintenance personnel. After the training program, which included installation and removal techniques, as well as ways and means of refilling bearing grease, there were no further problems reported and bearing life was extended from two weeks to six months, resulting in significant cost savings.

NSK super-precision angular contact ball bearings have the characteristics of long life, high precision and low noise. They are suitable for high-speed machine tool spindles. They use NSK's patented ultra-pure advanced materials and have long service life. In addition, the low-noise characteristics also make it an ideal choice for many modern Ideal for quiet, high-speed spindles on machine tools.
