NSK Saves Defective Spindle from Scrapheap
Bearings are often seen, particularly by people who don’t understand them particularly well, as small, simple and straightforward components. The truth is they are absolutely critical to many extremely complex and precise applications. When something goes wrong with a bearing, it can undermine a company’s entire operation. Equally, choosing the right bearing can make everything you do much easier. This can be true even when there is something wrong elsewhere…
For instance, NSK worked with one machine tool manufacturer which had produced 25 main spindle shafts with the wrong tolerances. Given those tolerances were not correct, the manufacturer was struggling to find bearings which matched their unexpected requirements. They approached NSK to see if we could help.
Our team of highly trained engineers analysed the entire application and proposed that the company adopt bearings with a special bore tolerance. Specifically, we suggested our very own Super Precision Angular Contact Ball Bearings, which would allow the customer to utilise their defective spindle shafts.
Regardless of bore tolerances, NSK’s Super Precision Angular Contact Ball Bearings offer customers high accuracy, long life and a fully optimised design, which is achieved by utilising computer simulations of temperature rise resulting from ball skid. They offer all this whilst operating more quietly than alternative options, being available with a range of different cage materials and with optional seals on offer within the standard ISO envelope.
"No matter what [the] issue might be...we will do everything we can to rise to the challenge"
Joerg Wagner, NSK Europe Sector Manager for Machine Tools.
The company was delighted to adopt the bearings, and quickly found that the target parameters of the spindle were met. As a result, the company was not only able to make use of the otherwise defective main spindle shafts, but also saved €20,000 into the bargain. A significant saving by anyone’s standards.
