Solve Industrial Motion Group (Solve), a manufacturer and seller of bearings and power-transmission component parts, announced the acquisition of SPB-USA, LLC., a factory-direct sales and marketing company of Sapporo Precision, Inc., the manufacturer of EZO Precision Ball Bearings.
SKF has developed a new hybrid deep groove ball bearing for high-speed applications. The new bearing is aimed at applications such as rail industry traction motors, as well as electric machines and drives. SKF already has three pilot customers, all of them OEMs.
Bearing calculations from Timken can now be easily generated in KISSsoft for the software’s registered users. Although the data is not visible in KISSsoft, it can be used in the background for calculation and design purposes.
Electrification has really brought ball bearings back into focus as the primary bearing in our drive systems. Some boxes have tapers on the slower shafts for stiffness and others are using a ball/cylindrical combo for efficiency. Regardless, we all face the same challenge on the primary shaft in dealing with the potential of 18,000–20,000+ rpm speeds coming out of the motor. Plenty of applications run 20,000 rpm; what makes the automotive motor unique is, in addition to speed, we are driving huge torques, frequent torque reversals and a huge range of temperatures both internally and geographically. Of course, this all needs to be suited for high-volume manufacturing as well. Adding full ceramic balls, a PEEK cage and a high precision classification is a really easy way to run greater than 20,000 rpm all day but is an expensive option. One bearing alone could hurt the cost competitiveness of your gearbox. In the case where a single bearing can change the landscape of your project, it is worth taking a little time to understand exactly what the drivers of our speed limitations are.
