SKF has opened a Ceramic Process Laboratory at its research and development center in Houten, the Netherlands, giving the bearing maker an in-house site for work spanning the full ceramic manufacturing chain. The company said the lab, called C-Pro Lab, covers everything from raw-material powder processing to engineering high-performance components and is intended to support wider adoption of hybrid bearing technology.
Hybrid bearings combine high-grade steel rings with silicon nitride rolling elements. Compared with all-steel bearings, SKF says they provide better electrical insulation, lower weight and reduced friction. Those characteristics are becoming more relevant as industrial equipment moves toward electrification and higher energy efficiency, increasing demand for bearings that can operate reliably in electrically demanding and high-speed applications.
Annika Ölme, SKF’s chief technology officer and senior vice president for technology development, said ceramic and hybrid bearing technologies are important enablers for clean, reliable rotation in next-generation industrial electrical applications. According to Ölme, the C-Pro Lab gives SKF full command of the end-to-end ceramic process, which should allow faster innovation, better material performance and quicker commercialization of hybrid solutions for customers worldwide.
An end-to-end competence center
The C-Pro Lab is positioned as a global competence center within SKF’s research and technology development organization. By locating powder formulation, compaction, sintering and surface finishing in one place, SKF researchers can prototype new material compositions, refine microstructures and improve process efficiency for high-volume manufacturing. The lab therefore connects early-stage materials work with the production requirements needed to scale ceramic components.
SKF identifies industrial automation, aerospace and high-speed machinery as key sectors for hybrid ceramic bearings. In high-speed electric motors, ceramic technology can help prevent electrical erosion; in other applications, SKF says hybrid bearings can cut friction by up to 50 percent. The company also points to extreme-temperature reliability as a reason these bearings are used in demanding environments. These benefits are tied to the combination of steel rings and ceramic rolling elements rather than to ceramic bearings alone.
The official opening brought together customers from railway, aerospace and drives applications, along with other stakeholders and H.E. Julius Liljeström, Sweden’s ambassador to the Netherlands. SKF framed the gathering as a sign of the customer collaboration needed to advance industrial innovation and sustainable technology.
The new lab adds a dedicated ceramic process capability to SKF’s existing R&D footprint. Its significance lies in joining materials development, component engineering and manufacturing process work in a single location, which SKF expects to shorten the path from experimental ceramic formulations to production-ready hybrid bearings.
