Abstract

A swashplate-type pivot bearing, or an axial piston machine that has the swashplate-type pivot bearing, which ensure reliable operation. The swashplate-type pivot bearing for a hydraulic axial piston machine has a housing section, a swashplate section and a multiplicity of rolling bodies. The swashplate section is pivotably mounted in the housing section by the rolling bodies and the rolling bodies are arranged in a full-roller configuration and/or without a cage in at least one rolling body row. The swashplate-type pivot bearing also has at least one follow-up device for follow-up adjustment and/or synchronization of the rolling bodies, which is arranged and/or formed at an end of the rolling body row. The follow-up device is controlled by a slotted guide.
