Method for producing a bearing assembly

A method for producing a control shaft, comprising:

• providing at least one pre-fabricated bearing assembly, wherein providing the at least one pre-fabricated bearing assembly includes:
• providing a bearing;
• arranging at least two rings on a respective axial front side of the bearing;
• pushing the bearing together with the at least two rings onto an assembly mandrel;
• pre-tensioning the at least two rings against the respective axial front side of the bearing;
• covering the bearing and the at least two rings with a protective material to produce the at least one pre-fabricated bearing assembly, wherein covering the bearing and the at least two rings with the protective material includes at least one of:
• pushing a shrink hose over the bearing and the at least two rings and heating the shrink hose;
• and
• winding a film strip over the bearing and the at least two rings;
• and
• withdrawing the at least one pre-fabricated bearing assembly from the assembly mandrel;
• arranging the at least one pre-fabricated bearing assembly and at least one control element on a control-shaft shaft;
• and
• removing the protective material from the at least one bearing assembly.
