The newly released high-performance two-flap nylon cage pushes SKF's hybrid ceramic deep groove ball bearings to new limits and provides greater flexibility in design choices. By allowing for higher speeds, it runs quieter and more efficiently than the bearings of a regular cage.

The newly released high-performance two-flap nylon cage pushes the hybrid ceramic deep groove ball bearing of SKF (SKF) to a new limit and provides greater flexibility in design choices. By allowing for higher speeds, it runs quieter and more efficiently than the bearing of the normal cage . Furthermore, it can achieve higher power density, resulting in more power output in motors of the same size.

SKF has released a new hybrid ceramic deep groove ball bearing for high-speed applications. The new bearings are targeted at the railway industry, such as traction motors, , motors and drivers. SKF has partnered with three pilot OEM customers.

The newly released lightweight cage helps increase the limit speed by at least 60% compared to traditional designs. In addition, nylon cages also help reduce friction, resulting in quieter operation and higher power density in applications.

SKF commercial and project engineer Andreas Pichler said: "The new cage design can effectively help our customers achieve higher power output and help further reduce the size of the motor."

By improving the efficiency of the motor, the new bearing can reduce energy consumption, improve reliability and thus reduce the total cost of ownership.

Two-flap cage is made of PEEK and PA66, which is 80% lighter than brass cages of the same size. In addition to running quieter, the bearings can also operate at lower temperatures, extending grease life and extending relubrication intervals. This allows engineers to be more flexible in design choices.

In addition, its ultimate speed is twice that of a conventional nylon cage and 60% higher than the brass cage.

rigidly connected cage strips ensure the firmness of the cage and help extend the service life under harsh conditions. The optimized cage design also eliminates radial deformation caused by centrifugation, i.e., the “umbrella effect,” which usually occurs on claw cages running at high speeds.

newly released bearing design will be aimed at OEM equipment manufacturers in the fields of railways, engineering vehicles, electric vehicles and industrial motor applications.
