I bought a second hand Braccio robot arm which is missing a single SR431 servo motor. I am struggeling to understand what is a proper replacement motor for this. I see that the official SR431 motor is out of stock or very expensive, so I am wondering if I can take a generic servo motor with similar specs?

Hi @wgvanveen and welcome to our forum.
What I’ve seen online is this Tinkerkit Braccio Rescue Kit, which would solve your problem, but it seems that it is sold out:
A good and cheaper solution could be this SpringRC SR431 from AliExpress: SpringRC SR431 Robot Servo12kg Large Torque Double Ball Bearings
I hope this helps.
