SKF releases new hybrid deep groove ball bearings to help small motors with higher power output
The newly released high-performance two-piece nylon cage pushes SKF's hybrid deep groove ball bearings to new limits and offers greater flexibility in design choices. By allowing higher rotational speeds, it runs quieter and more efficiently than ordinary caged bearings. Additionally, it enables higher power density, resulting in more power output in the same size motor.SKF has released a new hybrid ceramic deep groove ball bearing for high-speed applications. The new bearings target applications such as traction motors, motors and drives for the railway industry. SKF has worked with three pilot OEM customers.
Andreas Pichler, SKF commercial and project engineer, said: "The new cage design can effectively help our customers achieve higher power output and further reduce the size of the motor."
By improving the efficiency of the motor, the new bearings can reduce energy consumption, improve reliability and thus lower the total cost of ownership.
The two-lobed cage is made of PEEK and PA66, which is 80% lighter than the same size brass cage. In addition to being quieter, the bearings can also operate at lower temperatures, extending grease life and extending relubrication intervals. This allows engineers more flexibility in design choices.
In addition, its limit speed is twice that of conventional nylon cages and 60% higher than brass cages.
The newly released bearing designs will target OEM equipment manufacturers in railway, construction vehicle, electric vehicle and industrial motor applications.
