Schaeffler has presented a new product lineup, which was specially designed for electric vehicles in the form of the TriFinity triple row wheel bearingand the high-performance ball bearing with a centrifugal disc. These are said to be characterised by particularly high efficiency, among other things.
The supplier founded a new bearing division in its Automotive Technologies division at the beginning of the year and sees e-mobility as a great opportunity for its bearing technologies business. Dieter Eireiner, Head of the Bearing Division, expects ¡°strong business development in the coming years and sees sales potential especially for ball, cylindrical roller and tapered roller bearings¡±. The company is involved in ¡°promising development projects with well-known vehicle manufacturers¡±.
The three-row TriFinity was developed especially for electric drive trains. According to the manufacturer, compared to a standard bearing with two rows of balls, TriFinity enables ¡°a transmission of more axle load with a significantly higher service life and rigidity without changing the bearing dimensions¡±. With the change from a tapered roller to a ball bearing, a ¡°significant improvement in frictional torque and stiffness¡± is possible, resulting in a 0.7 per cent reduction in power consumption in the vehicle in the FTP75 cycle.
The new high-performance ball bearing with centrifugal disc is designed to combine the advantages of an open bearing with those of a sealed bearing, says Schaeffler. A CO2 reduction of 0.1g/km is mentioned. However, sustainability also comes about thanks to another characteristic: the new bearing has ten times the service life of an open bearing at lower costs.
