I want to lubricate the nylon rotors that my mower blades turn in. What
is the best lubricant to use? I have heard that oil will deteriorate the
nylon and that silicone is too weak. They are really getting noisy and need
something. Thanks

i wouldnt know completely what is best but how about give it some oil
for the moment or silicone either or both just a little amount to calm
it down only if it is in desperate need and then wait for more answers

but if it were me id add a bit of oil to the rotors only just enough
tho

Lubrication is likely to be a short term solution at best.
I'd probably try some polyurea (bicycle) grease since I
happen to have some around.

But if nylon bearings are sufficiently worn to flap around and
make a noise, it's time to replace 'em. Just check to see
that it's not something else generating the noise.

Oil won't harm nylon, which is impervious to most petrochemicals (at
least those found around the house).

It might seem like a wild and crazy idea but have you considered reading
the manual or contacting the manufacturer? Surely either of those would
yield better information than strangers who have no idea what sort of
mower you are using.

Use Lubriplates Aero grease. It's compatible with plastic and has
good low temperature qualities.

Below is a guide to chemical compatibility for many materials:

Nylon is compatibile with almost all oils.

Just for kicks I selected aluminum and petroleum. It has a D
rating - Severe effect, not recommended for any use. What is
the reason behind this?

Aluminum block car engines and pistons? Huh?

By "petroleum" I think they mean crude oil, which can contain stuff that
corrodes aluminum.

If you do the same check on "oils:mineral" (which is what ordinary
petroleum lubricants are), it comes up A.

Aerosol grease would be easy. Most grease and oil tend to attract
and hold dirt/dust/scuzz. I use a Teflon filled anti seize on
similar things and have been quite pleased. Here are some
examples:

brands.

Yes, replacement. Typically you replace such bearings when they act as
you describe.
