SKF and DMG Mori join forces on bearing monitoring technology

SKF has teamed up with the machine tool manufacturer DMG Mori to use SKF’s Insight Super-precision bearing system to push the performance of machine tool spindles, while maintaining or improving their reliability. The system measures the loads, speeds, temperatures and vibrations experienced by a bearing in real time, and fits in the same space as a standard bearing. It is accurate, fast and robust and can be applied to any rolling element bearing to enhance the performance of machines or processes.

In a joint programme, SKF and DMG Mori will develop and validate the technology in machining centres. Teams from both companies will test the system and ensure that it meets the performance requirements of the machine tool industry.

The system will allow DMG Mori to improve lubrication control, enhancing bearing lives and reliability, as well as facilitating precision machining. These improvements could lead to higher productivity and enhanced workpiece quality.

Dr Naruhiro Irino, director of DMG Mori’s Advanced Technology Research Centre, says the development will allow real-time monitoring of bearing temperatures, loads, and vibration during machining, “offering insights that were previously beyond reach. We look forward to accelerating our Machining Transformation (MX) by integrating the advanced technology of SKF into our new ERGOline X with Celos X human-machine interface, setting the stage for the next leap in productivity and efficiency”.

Annika Olme, CTO and senior vice-president of Technology Development at SKF, predicts that the collaboration “will unlock new technology benefits for customers and end-users”.

The Insight technology has already been proven in a variety of industries and applications, integrating intelligence without compromising the compactness or stiffness performance of SKF’s Super-precision bearings. It can help to cut noise levels and heat generation.

The bearings are suitable for other precision applications, such as high-speed finishing stands for steel wire, and engines and transmissions in racing cars.
