Ceramic ball bearings

[diesel pig]

Ok MicoBlue Bearings can only do 3 of the 5 bearings I need for the 2 wheels and cush drive if wish to do a set up for lowest rolling resistance possible. So do I get the three MicoBlue bears and 2 of the best steel bearing I can get. Or do I get a whole other brands set up of 5 CERAMIC BALL BEARINGS from some where else? Is there anyone else I can could trust for good motorcycle wheel CERAMIC BALL BEARINGS? Any thoughts on the matter would be helpful. Cheers

May be expensive to keep changing the bearings in order to maintain the initial low friction: "An often neglected part of tribology is how a bearing responds as it wears out. The graph below shows a comparison between two steel bearings (SKF and NTN) and a Ceramic bearing (Enduro). Initially the Enduro bearing has lower friction, at around 600km of use, the ceramic bearing has worn a track into the comparatively soft steel races and the bearing friction starts to increase dramatically. It is comfortably higher than steel bearings after a modest running in period. Hybrid ceramic bearings are the equivalent of trying to run a locomotive on an asphalt road – the hardness differential causes the road (raceway) to become damaged." https://www.hambini.com/ceramic-bearings-vs-steel-bearings-an-engineering-analysis/

Well that is very interresting. I think I would be better for me to get MicroBlue coated steel ball bearings as I would want them for a motorbike I would be touring with. If it was a racebike that would be a different story.

If you want to go whole hog DP, remove the wheel bearing integral seals and replace other wheel seals with teflon. Coat the axels with some clever ti coating
but honestly you will gain more with less sticky thinner tires pumped up tp 40 psi and eating less pies... some gains are not worth the pain
Bradley's first design book offers good advice on what aero actually works.

Sorry how is this going to be noticeable on a touring bike?
I didn't even bother pulling the seals off, washing the bearings of grease and oiling the bearings every morning. Too much hassle on a racebike, but several production racer did it.

Brake drag and gritty chain will make more difference. You could run intelijet kits on carbs with an egt so you adjust the mixture from your seat during the ride. But why bother?

[SaferRides]

The bearing seals cause more drag than bearing type. Pop the seals off a ball bearing to see how much difference it makes.

I will have to go over the parts book and work out how many seals there are on each wheel. I would want sealed from dirt ingress but not over seal it. Much to think about. Cheers

So what is the End Game here?

Chasing 0.05% here and there could net you maybe a 1% gain over a well maintained bike. At what expense vs extra petrol?

Reduced brake drag, oiled chain and adopting a permanent racing crouch would do far more. Try skipping breakfast, carry no spare change, take out the toolkit and polish your leathers.

Should only be single side seals - facing out. Front wheel will have two bearings, rear will have 4 - two in the wheel and two in the cush drive. You could go for shielded rather than sealed, but expect to spend more time on maintenance. What is you intended use for the bike? any off-road will surely demand sealed or your projected saving will be cancelled by carrying spare bearings and tools to change them

I will be fitting a scottoiler (I am pretty sure of that now) setting the brakes up for little to no drag as well. This is more about not throwing that away by having badly set up and high rolling resistance wheels.
As for the Aero you lot keep going on about, I intend to do a rest-o-mod type of deal where she will look from the outside like a '71 machine with any mods looking from the outside like they were done no later than '75.
That's why I was interested in ceramic bearings because from the outside one couldn't tell if they were being used.

P.S. Just to add to what I was saying about the rest-o-moding, I think if I get a new type of E-scottoiler , I could hide away 95% of it behind the frame work with the only visible part being the tube that oiled the chain and I think I could do that in way that was only visible if one really went looking.

P.S. to that P.S. does this all really matter? No not really. But it matters to me, and that is the only person I am trying to please, I enjoy waffling about it to others that don't seem to mind me posting about it. Cheers

No off roading as such but I don't want to be afraid to ride it down a shingle Road. You make a good point about the seals. Do I want to ditch the original wheel seals and use the seals on the outside face of the bearings? or ditch the bearings seals and get new wheel seals? The reason I am going on about this now, is I intend to have the wheels re-laced with Alloy rims (something that more matured riders assured me happen often in the 70's so should work well with the whole rest-o-modding thing) and the Hubs lightly polished, so I thought I would replace the bearings as well and since I don't want to do it again if possible, I thought I would do the best job I could.

P.S. I just had a thought. If the consensus is use the bearing seals. I could sand down the lips of the original wheel seals so they cannot genearate any drag but look like it is still straight out of '71.

[F5 Dave]

Your original wheel seals are best defense against water and grit getting in. I'd leave them the same but new on good surface with grease.

You do you we are just giving you shit..
I have this mag.... tells how to lighten crank and add tz bearings .... triump truztons and velos and bsa had fairing in the late 60's not my style i like the TZ look.

ps diving down rabbit holes is fun....
Francis beart who prepared bikes in the 50-70 normally aermacchi or manx's, He used the work on the wheel until they would spin for hours hundreds of hours of tiny changes ,fork a 1/2 inch lower subframe a 1/4 inch lower bolts drill out he used carbon fibre for fairings i early 70's late 60;s thin paint dimple drilling side covers... pure porn...

Thanks to the internet I have have found out Suzuki T350's and T500's don't just look similar, they use alot of similar parts and in alot of cases the exact same parts. With T500's still being popular in the UK and somewhat popular in the USA it maybe still possible to get a lot parts for them. So I will go looking for some wheel seals. If I can get some new seals, I will go with H/Q steel bearings.

[diesel pig]

Oh S..T, I just thought when I get O-rings, I don't go to local bike dealers to get them. I go to a local O-ring whole saler. They always have what I want. Is it the same deal with seals? or is that too specialised?

bearing shop ....if you wanted teflon they are a bit harder to source.

I don't think they are teflon but I just don't know. Hoorah, Something else to look into. It's was just when I put a suzuki part number for one of the seal's into google the number of entry's seem endless and it got me thinking are seal's just made to common size's and are alot easier to get than I thought.


I must abmit I thought seals were made special size's for each use but it would make sense they are made to common size's like bearing's and O-ring's.

lists the size for o-ring and seals
https://www.cmsnl.com/suzuki-t350-1969-1970-1971-1972-r-j-usa-e03_model16262/partslist/85340.html

youre welcome
they also list of the other bikes that same part fists if you log in
https://www.cmsnl.com/suzuki-t350-1969-1970-1971-1972-r-j-usa-e03_model16262/partslist/

at times they don't list the bearing, only a part number but the pic is the actual part and often you can read the size code

Also for instance the steel clutch plates fit over 200 different Suzuki models

For once I found this site on my own. It is what got me to realise that alot of parts between T350's and T500's were the same.

Bike shops sell bearings and seals too?.

Actually it's got too hard to deal with yer skf and saeco type places. They put the price sky high so they can offer trade 50% off and good customers 70% off and better customers 73% off.
It's the Briscoes model but then they got dicky with public.

Online.

Seal imports are still good fortunately.

[SaferRides]

+1 for Seal Imports.

Be aware that there are different seal "types", like there are grades of bearings. I bought a seal from a bearing shop and it wore a groove in the ally spacer. Oops.

OE parts are safest for Jap bikes if still available. I don't know what it's like buying Suzuki parts for older models locally, but there are websites in Japan who offer really good if slightly quirky service.

Seal Imports! I am annoyed with myself for not thinking of them! I use to get crankseals for my Bucket from them. Thanks for jogging the old memory!

The couple of times I have dealed with websites in Japan it has always ended well but calling it 'quirky' is being very polite.

Talk of the wheel seals. As it got thinking of the steel wheel spacers they are running on and I should sent the ones in good nick to be sent to Superfinishing in Auckland to there to get the surfaces done real nice and smooth.

Make them out of alloy and polish them


Tradezone in Flaxton road have bearing and seals in stock, I got seals for my Beta wheels from them last weekend

Also https://www.abdgroup.co.nz/ have a search tool where you can put in bearing or seal dimensions or numbers and it gives you all the options in that size, you can put in one or more dimensions to search

I make ally for race bikes. Did for dirtbike and wore groove. Turn down a lick and press on stainless sleeve.

All the spacers in the wheels are alloy, hollow bolts everywhere, etc. Just unfortunate how heavy the wheels are, but then they've survived NZ roads for 26 years!

I always clean and regrease the seal lips when I have the wheels off. Don't know how much it helps but it only takes a few minutes.

Well a hell of alot to think about. Thanks for all the input. It might be a week before I know what I will do.Cheers

These would look great on a T315 (350)

I have got there UFO's to try first. I will see how they go.

[diesel pig]

I have talked to Darren at superfinishing and said he can do Steel ball bearings, as long as they have no seals in them. So I think that will be the way I go.
