Here's what I found with my Nutra-Ninja. Melted plastic after unscrewing the wheel driving the blades. Note: It's a left-hand thread. Applied some silicone spray and this eliminated the vibration (for now anyway, will see how it goes).

Took the extractor blade assembly apart to work on reducing the amount of noise coming from the blender. The model I'm working on is the "Ninja Ninja Nutri Bowl Duo with Auto-iQ Boost", models NN100, NN100A, NN101, NN102 - these model numbers use the same motor and extractor (blade) assembly.

Took the extractor blade assembly apart (again) to work on reducing the amount of noise coming from the blender. The model I'm working on is the "Nutra Ninja Nutri Bowl Duo with Auto-iQ Boost", models NN100, NN100A, NN101, NN102 - these model numbers use the same motor and extractor (blade) assembly.
Removed the bearing retainer:

Pulled out blade assembly, cleaned and lubricated it with silicone spray. Then reassembled. Reduced the noise level a little bit.

To see where the most of the noise is coming from, the motor can be run without the extractor blade assembly installed. Just attach one of the cups and briefly run the motor to see how much noise is generated. Compare to noise level with extractor blade installed. For my blender, there seems to be 2X the amount of noise when run with the extractor blade vs just the motor running.

Note: there are two stainless steel bearings installed. Manufactured by Ningbo Zhenhai Hualei Bearing Co., Ltd - (HLGS). Part number is: S698RS. Bearing size: ID x OD x hole size = 8mm x 19mm diameter x 6mm thick. Bearing is a sealed unit.
