How freely do your Hope rear hubs spin?

[Peach.]

Haha haha, Chris King is is just like any other CK handbag. It's all just rebranded.

 

I have cleaned and reused pretty much every type of bearing, Pivot, headset, BB.

If their is no play the bearing can be cleaned and reused.

I have taken a seized bb bearing back to prefect use with some parrifine and new grease.

 

If you Can waste cash on new bearings when you don't need then good for you

[Wyatt Earp]

Easy tiger!

 

I do agree that CK bearings are are of a superior quality to Enduro, SKF, NSK, whatever.

 

I was simply stating that there is indeed a rubber seal behind the snapring.

 

I will explain, what I meant by rubber seal was it is not what my friend Skylark has in mind.

The CK rubber seal is very thin, almost paper thin.

The CK seal and the FAG seal are not the same thing.

 

Here we have a Skylark bearing.

 

Here we have a Chris Kink bearing, and yes this is mine .

I hope this helps some people .

You seem quite sure about this.

Care to share your source?

 

Yes, the hundreds of bearings I have replaced and bought over the years .

You say you have opened many bearings, that little highlighted bit calls you out as a liar.

[Skylark]

NO

 

You know that for a fact or you want to give them a quick call, maybe phone a friend?

The biggest bearing manufacturers in the world with the biggest bearing R&D budgets and the most amount of tooling won't able to make a bearing of the same precision and quality as Chris King uses on bicycles?

 

Just to confirm you do know now that 2RS refers to a bearing having two 2 rubber seals and has nothing at all to do with the quality of the bearing?

 

Just so no one is under any illusions about anything bearing related on this thread.

No need to call a friend, you are terribly confused about the layout of the normal sealed bearing V bearings put together by Chris King.

This is the rubbish you are referring to, I forgot to attach this picture for your perusal.

But I will strike a deal, I will give you some time to find me a CK bearing form the many bearing manufacturers out there.

No, nut I assumed so, because it must have been all to call a Chris King bearing a rebranded bearing.

[patches]

Both respond the same to contamination and have the same requirements.

 

Bearings with the same level of quality and precision as those made by Chris King can be ordered from FAG/SKF/BMG, they are just very expensive. By the way 2RS refers to a bearing having two 2 rubber seals and has nothing at all to do with the quality of the bearing.

NO

 

That's quite an assumption.

 

Whilst I doubt any of us here are true experts on the matter of bearings, there are certain facts.

 

Large manufacturers like NSK and SKF have a "super-precision range". Yes, not the over the counter stuff from Bearingman. These are the sorts of bearings used in high speed and demanding applications like multi-axis CNC milling machines etc.

 

They are subjected to WAY worse than what any MTB goes through. To produce such bearings these companies have top end machinery (as awesome as CK is, I highly doubt their machinery is as advanced as that of said manufacturers).

So in a nutshell you are saying you are not skilled enough to take the seals off a 2RS sealed bearing and that's why you never open them?

Because the 2RS bearing manufacturers themselves specify that the seals on the 2RS bearings can safely be removed for servicing and regreasing.

I was referring to when you dismissed Super_mil's notion that a CK bearing has a rubber seal beneath the steel.

 

I know this setup is rather different (and as stated before by yourself and others) a "servicable design".

Maybe a different view.

I have removed more of those hard plastic "seals" that get labeled as a rubber seal to know that it's a waste of time .

Then I would like to see where the manufacturers specify that, perhaps on some of the bigger bearings.

You seem in great hands as I said.

I will lay it out a bit clearer.

I know what you meant, I just got in to a flurry when I was thinking of the 2RS hard pieces of plastic in that the CK bearing does not have the same engineering flaw.

I should have said that the Chris King rubber seal is not what Super_mil might have had in mind.

My humblest apologies for the confusion.

A RS seal is rubber with a rubber lip to seal onto the inner race, most have a metal frame, no plastic anywhere, although a layman would probably call it plastic. Any mechanic worth his salt should be able to safely take a bearings rubber seal on and off no problem.

 

RS Contact seal of acrylonitrile-butadiene rubber (NRB) with or without sheet steel reinforcement on one side of the bearing

2RS RS contact seal on both sides of the bearing

If you consider those things real rubber seals, those things that have a metal piece coated in rubber, the your layman's qualifications must be with a distinction.

Have fun, especially when the race starts pitting and the balls start losing their roundness.

Sorry for joining your topic where you asked for help only to dish out expert advice to yourself.
