Ceramic Bearings=Rainyday bearings?

Post by Mark Pa » Sat, 07 Oct 2000 11:16:56


Hi all,

The weather here is starting to get wet and rainy, so it got me thinking
about skating in the rain (or at least when the park is still wet). I'm
balking at the constant cleaning and reoiling that will entail with my
bearings though, which got me thinking ... if I use ceramic bearings, would
I have to disassemble and oil them after a rainy day skate? I mean, seeing
as they don't rust and all ...

All the ceramic bearings I've seen have ceramic races only.  Best to
find out what type of steel is used in the balls.  Anything but 316L
stainless will rust and 316 is probably too soft for bearing use.
Industrially there is a plastic raced 608 bearing with 316 balls used
in harsh environments but the load rating is held to 300 lbs per
bearing.

     Lubrication does much more than protect the metal surfaces from rust.
It reduces friction to allow easier spinning, which in turn reduces/prevents
a build up of heat, which will destroy skate bearings of any material.
    A practical solution to foul weather skating might be to use
older/cheaper bearings lubed with water resistant grease. They will be
slower- not because their age/value, but because of the grease vs. an oil
type lube.
    The advantage of grease is that it doesn't wash/flush out of the
bearings, or foam as readily as oils will.

SKF makes bearings with one ceramic ball and the rest is metal.
They say that the ceramic ball smothens out injury on the raceway
without being hurt it self.

For rainskating there are 608RS wich is ***sealed.

I have wondered about the practicality of using silicone grease.  It is much
more water resistant than the petroleum greases but unfortunately is very
viscous.

You can find it in the plumbing supplies in a decent hardware store.  It is
used to lubricate *** O rings that would be destroyed by petroleum based
greases.

Totally ceramic bearings?  Expensive.  But a great marketing tool.

No not overseas, but try at XC-skii shops, theire are using this
bearings in rollerskiis.
But why not try SKF, they makes those bearings.

I have used white lithium grease for this purpose (Specifically, Campy
bicycle grease).  I don't know the long term resiliency in skate bearings.
Anytime my skate bearings have gotten wet I soak them in WD-40 as soon as
possible, believing the solvent properties will cut the grease, and the
water displacing properties will coat the steel, and hopefully save the
bearings. However this stuff stays in some of my bike wheels all season(and
longer), after being exposed to rain.
I've yet to get my really good skate bearings wet, so its hard to say this
is a totally effective procedure.

http://SportToday.org/ has some.

They're listed in the "mini bearing" area.  They're unrated but I've had
good luck with them.  Stock lubricant is pretty slow.  They work well
with oil but I don't know if that seriously reduces they're water
resistant properties.

I just read an article in "blue" about Eddy Matzger's in-line skating
adventure up and down Mt Kilimanjaro.  In the related article he did an
interview and was asked about bearings and rainy day skating.  This is
quoted from the article:

******************

        blue:  What about the waterproofness of bearings?

        EM:  That's a question of the tolerance that they are built with and
the quality of the steel and also the lubricant inside.  The ones that I
brought up to Mt Kilimanjaro have this gel inside and are pretty hydrophobic.

        blue:  It's so much fun to skate in the rain, but apparently it trashes
your bearings and the people in the skate shop say, "If it is raining,
walk.  Just decide you're not going to skate that day."

        EM:  No, no, no!  No need.  It's a question of where to find them and
what to ask for.  Twin-Cam is the bearing I use.  I put in a pair in the
early spring, and I'm still on 'em late in the fall even though it
rains.  I race and train and go off-road and everything on the same set
of bearings and never clean them.  I just wear them until they give up
the ghost, then I pass them onto the kids in Tahiti or something and
they give them new life.

Ceramic Bearings=Rainyday bearings?

I work as a courier using my inlines and, yes, I have been stuck in the
rain many times. When it rains here in Dallas, it pours. Like four
inches of water in the highest part of the road! It's not fun skating in
that kind of rain because your skate liner or socks or expensive leather
speed boots will be completely soaked. As for bearings, I've used many
brands, but for rain, I definitely endorse Twincam. When Eddy talks abut
the "tolerance" of the bearings being a factor in being a good rain
bearing, I don't think he meant the "ABEC" issue. Twincams are designed
with a bevel on both the inner and outer races. This "labyrinth" design
keeps gel lube in and contaminants along with most water out. According
to the website and by my personal experience, the "TK Racing Gel" used,
is designed to adhere to all the metal surfaces in the bearing. The
theory goes, what water does get in will eventually evaporate while the
gel remains, protecting the bearing surfaces. The quality of the steel
itself seems good to excellent. The Twincams have survived many
"dunkings" in water like the rainstorms spoken of earlier, with
absolutely no post rain cleaning/ soaking/relubing. Contrastingly, one
puddle was all it took to foul some stock BSB ABEC 3's. The BSB's seem
to have a large gap between the inner race and shield. In goes LOTS of
water and other crap, out goes the lube. As Eddy said, the best way to
use Twincam is to just skate on them till they aren't as good as they
were. I know that's not fun for you tinkerin' gearheads, but great for
those that want to spend precious little time available skating, even in
the rain, rather than maintaining bearings. So if rain skating is
inevitable, my recommendation would be Twincam ABEC 3's (ABEC 1's use
grease). Use them till you wear them out, then throw them away. I'll try
to find the link on the Twincam webpage and post it.

Now, if someone would design a neoprene gaiter to keep the skate boots
and socks dry, i'll be your first customer!

kinda fun :-) I haven't tried it yet in my Kinetics, but the Ultrawheels
went through some light rain before. They started squeeking about 2
weeks after that.
The way Eddy tells it, the gel plays a big role in this equation. Anyone
with any ideas on this? Someone (Bill?) also mentioned using the
silicone grease that plumbers use. Anyone else tried this?
The idea is this: I wanna not stop skating when it rains. In fact, when
it rains is when the paths are REALLY clear for skating :-) If I can be
sure all I need to do is pack my bearings with the right kinda grease,
then hang the ceramic bearings :-)

I've kind of a question--

What kind of wheels are you people using to skate in the "rain?"

I've passed through small puddles, but how you even stay upright in
standing moisture at speed is escaping me.
