It was in an engine that had not been running in years.
It is stamped:
"Aetna Ball Bearing Manufacturing Co. A-7580-B 3"
NOT just "AETNA"
NOTE: Unlike the new T Bearings, this bearing is open on the ID so grease can get inside bearing when the Zerk is used to apply grease.
Maybe this is a genuine Aetna bearing?

That's like the one that was in my car, same stamping. Never gave any problems. I almost reused it since it felt better than the new FM bearing.
