Schaeffler acquires a manufacturer of Hybrid Bearings components

Rolling bearings with ceramic components are characterized by low friction and wear as well as high precision and stability. They are also increasingly used in applications designed to protect mechanical components from the flow of electrical current, such as the drive motors of new energy vehicles that have become popular in recent years. CERASPIN's many years of experience and expertise in development and production at all stages of the value chain from raw materials to finished components allow the company to offer high-quality and technologically advanced products.

In fact, CERASPIN is a well-known supplier in Europe and has been a supplier of Schaeffler Group since 2004.

The acquisition of CERASPIN further strengthens Schaeffler's position in areas of future strategic importance. Dr. Michael Pausch, Chief Technology Officer of Schaeffler Industrial Division: "CERASPIN's expertise in rolling bearing ceramic components is of great importance to Schaeffler. With the acquisition of CERASPIN, we are strengthening our supply chain, especially in Europe. At the same time Build a strong position in high-value components in strategically important growth areas. According to the acquisition agreement, Schaeffler will acquire 100% of CERASPIN's shares, and the transaction is expected to be completed before the end of the fourth quarter. As is customary, both parties agree not to disclose transaction details.

FAG Hybrid bearings - usually bearings with ceramic rolling elements and steel rings – have become the standard in machine tools as well as in aerospace engineering many years ago. The best-known example are hybrid spindle bearings. And now, hybrid bearings are increasingly being used in general machine construction applications as well. This applies especially to applications where problems arise with conventional bearings, e.g. with regard to lubrication, speed, temperature or current passage.

The service life of the FAG hybrid bearings, both with grease and oil lubrication, is several times that achieved by bearings with steel balls. Under starved lubrication conditions, it is many times longer. Friction and adhesion between ceramic and steel (and, consequently, wear) are very low, especially at cold starts. In sealed bearings, the high degree of cleanliness in the rolling contact areas is maintained – a precondition for a long service life. Due to the additional sealing effect in both directions (inside and outside), the grease is retained in the contact area, and the ingress of contaminants into the bearing is prevented. Good dry running properties, thanks to their low adhesion and friction, prevent hybrid bearings from seizing under starved lubrication or dry running conditions. In many applications for hybrid bearings, the grease life is a more decisive factor in the designing of the bearings than the fatigue life. Electrical properties Due to their high electrical resistance, HC bearings act like insulators, they are insensitive to capacitive currents. This means that they can be used for all applications where there is a risk of passage of current. High speed suitability The attainable speed of HC bearings can be estimated to be more than 10 % higher than that of standard bearings.
