OK to use grease on bearings w/ NYLON cage/retainers?

Post by FNGu » Fri, 15 Apr 2005 15:40:58


Just wondering why the Bones type bearings, and all those with that type of
nylon ball cage, are always oiled, never greased?

If there is an incompatibility, is it chemical, mechanical, or...?

Thanks in advance, FNGuy

"all those with that type of nylon ball cage, are always oiled, never
greased" is a false statement.

There is no incompatibility.

As far as Bones bearings only comming with oil, that is obvious.
Bones are expensive.
People who want them usually want to go as fast as possible.
People who want to go as fast as possible usually use oil.
There is almost no market for Bones bearings with grease.

To concur with Bill, there is no reason you can't use a grease. As Bill
suggests, people who spend that kind of money on bearings (like me for
example) are looking for optimised performance, so oil is the choice of
lube.

The other thing with the nylon they use in the cage (a PTFE infused
Nylon like Delrin as far as I am aware), is it has some porosity to it.
Therefore, some excess oil may be taken into the cage and stored for
when things be a but dry or hot. Some friend of mine used it to make a
gear demonstration rig for a project in uni, and they chose it for
those properties.

False? Err, I meant FROM THE FACTORY.  Name one nylon-caged bearing that
comes greased from the factory... can't do it.

But I said Bones *type* bearings.  Perhaps I should've said Bones
CONFIGURATION.  For instance, there's the low-end Bones Reds, marketed to
the skateboard crowd.  Virtually NO ONE considers these inline speed
bearings, yet they come oiled.  Then there's the even cheaper and sloppier
Mini-Logo bearings, also Bones-esque, also oiled.  Can't think of any other
nylon-caged brands right off the bat.

Oh well, my Reds were cheap, ergo, I shall experiment on them with grease,
that gooey nectar of the maintenance-averse skater.

BSB Swiss bearings are nylon-caged and they come with grease.

Thanks.  I've now greased the Bones Reds and they're better than ever.  My
next set of bearings that come oiled will get the oil replaced with grease
right away, to avoid the accelerated wear.  Plus I like the way grease
gathers at the inner race, and acts as a barrier to keep out dirt.

R. Nett of nettracing.com thinks the BSB Swiss are a great combo of speed
and longevity, so I'll put them on my list.
