Trying to use vibration to insert tubing- need guidance
(OP)
I am sliding a small metal cylinder into plastic tubing (nylon) and keep getting high frictional forces (ie it jams or damages the plastic)- I can't use lubrication - so I thought about vibration to keep it dynamic- any thoughts or guidance?

Do you have a length to diamter issue?
Do you have the ability to use either of the following to aid in assembly - heat to expand the nylon or expand the nylon with air pressure during assembly.
good luck

For temperature method try cooling metal tube and warming plactic tubing and then work very fast before temperatures equalize.

To answer the length:diameter ratio question, it's 60:1, so there is a lot of friction condition and potential for damage / failure to complete the insertion.
I do have a cooling option available (I use electronics cleaner duster spray from a can), it's just not a long term, operator friendly option. I also have compressed air-vortex chillers available, but they get noisy.

Spin the cylinder during insertion?
I can expand and pop the handgrips right off my motorcycles with compressed air. How much would the nylon have to expand to make clearance?
