Rolling bearing arrangement and planetary transmission comprising the rolling bearing arrangement

A rolling bearing arrangement, comprising:

• rolling elements;
• and
• at least one cage guiding the rolling elements, the cage having at least one contact zone for sliding contact with a further contact zone, the at least one contact zone has a treated surface with a maximum compressive residual stress of 900 to 1200 MPA obtained by blasting with solid particles, the compressive residual stress extending with a changed value down to a depth of at least 0.25 mm vertically under the treated surface.

A method of producing at least one contact zone of a cage, comprising the following steps:

• blasting the contact zone with a blasting agent in form of round particles having a size in a range of 0.2 to 0.5 mm with at least a surface hardness of the particles being at least higher than a surface hardness of the contact zone.
