Importance Of Right Installation Of The NSK Super Precision Bearings
Jul 02, 2018

NSK has solved the recurring problem of spindle bearing failures in four CNC machining centers in a leading automotive industry supplier's factory. In view of the failure rate of the spindle bearings every two weeks, the program now saves €32,880 per year.

In order to investigate the cause of the failure, NSK needs to investigate the entire application and maintenance process. NSK experts observed the installation method of the maintenance department and found that the main problem came from the faulty operation of the ultra-precision angular contact ball bearing.

NSK super precision angular contact ball bearings have long life, high precision and low noise, suitable for high speed machine tool spindles.

Properly installed bearings are essential for optimal operation and continuous maintenance of industrial machinery. Proper training and the use of the right tools are very important. With this in mind, NSK has comprehensive training for the company's maintenance staff, including installation and disassembly techniques and advice on replenishing bearing grease. No other problems occurred after the training, bearing life was extended from two weeks to six months, which significantly reduced costs.

Consider the bearing failure every two weeks (four machines), as well as the cost of replacement and downtime. After NSK investigations and research and improvement, only two bearing replacements are required each year, equivalent to an annual savings of €32,880.
