[Closed] Bearing, bearings, bearings, Who thinks they know the score?

Wow Pierre, I like it - but maybe too much effort involved? 🙂

I still seriously want to see the bearing puller.. no piss taking, as i said i am genuinely interested.

Do you have any pictures of it at all?

Go, Kaesae, Go!!!...you tell the fools, the disbelievers, the tv drones or whatever you call them.

Can we have another theory please.

Oh, and the bearing puller does sound genuinley interesting, pop it up, lets have a butchers then.

He must have opinions on 'What tyres for....'

you seriously expect him to post his bearing puller for everyone to lynch the idea regardless?

Its easy to be clever and make snide remarks behind the anonominity of the internet but how many of you have actually got off your arses and tried to actually do something productive?

If you dont agree with him, dislike his sales patter, attitude or product then just ignore him. Don't section him out and try to destroy his business, thats not really very fair.
I thought mountain biking was generally a friendly sociable scene and sport
Each to their own, he believes he is providing a service, he stands by his beliefs and it seems to be a service enough people want.
Yes he can come across as an arse, yes his theories may be questionable to the more educated of you here but at the end of the day, if you don't like it, just don't read his patter, buy your bearings elsewhere and you will be none the wiser and non the worse off

If other people want to buy bearings from him thats up to them, personally I need new bearings, I normally use my local bearing supplier. I am willing to give this guy a break just once as until I personally try something then how do I actually know its any better or worse
I may be making a mistake, I may not, at the end of the day I cant be ar$ed removing seals and messing with grease myself to see if it lasts longer so Im not going to loose out by much am I, a few bearings are hardly the most expensive bike part I have ever had to buy

I think this thread and the abuse in general (on both sides I add) has run its course and gone far enough
Initially I kind of agreed with the mob and laughed along but seriously its looking a bit pathetic and childish now

This thread's like a scab thats not quite ready to be picked, I just cant resist having a little look in every now and again and watching it bleed.

Bleak.

His bearing puller is on youtube

Nothing new there then 🙄

What a tool. 🙄

You could get a bearing like that out in a fraction of the time using a sleeve anchor.

There must be a bit more to the one he raves about, the one on Youtube won't do blind bearings.... ?

Some video editing would have been good, the dropping of various items got a bit tedious, but then I have read this thread from start to finish ..... !!!

or a screwdriver and hammer!!!

My bushings are working superbly as usual 8)

[b]**** OFF! Please?[/b]

NO!

@chunkymtb. Yes, my Nicolai uses bushings - just work...

Bushings here too. Kaesae proof.

The five main factors that contribute to bearing failure in MTB applications.

1)Bearing material.
2) Bearing design, caged or full comp also the seal design and interface between the seal and races.
3) Bearing greasing, how much and what kind.
4) Bearing tolerances.
5) Installation and maintenance of the bearings.

Day 1 again

Day 2

1)Bearing material
As you can see the budget bearing being made of a much lesser quality material is not holding up very well.
The performance bearings are doing a lot better, the enduro in this test is doing a little bit better at this stage than the SKF’s, it is however an outdoor specific bearing. The SKF and most other performance bearings have a lot better seals than the enduro bearings, which is why a favour them. The seals make it much harder for contaminants to get into the bearing.
If you’re bearings rust on the inside you will get much quicker ware and there will also be a higher risk of them seizing.

You will also spend far too much time replacing the bearings and get no performance gain.
If the bearing collapses which is what happens a lot with the cheaper bearings, a good example of this is the JNK bearings that Specialized run. You will have a much harder job replacing the bearings, me I could do without all the hassle.

Seals as a sub category of bearing design.
Next I want to discuss seals and the outer also inner race interface between the two.

The photo shows a budget bearing on the left an Enduro in the middle and an SKF on the right.

If you look closely you’ll see that there is a groove cut into the SKF bearings inner bore race for the seal to fit into. You will also see that the budget and enduro seals are almost identical, however the SKF seal is much thicker and has a superior design.
The SKF seal on the inner race interface has better quality rubber and is also ribbed, this helps it to keep the fit as tight as possible.

The SKF seal will greatly reduce the amount of water and other contaminants that get into the bearing.

Let’s be hearing you then, you know you can’t resist!

Bushing for the win 8)

You like Honey then!

Let’s take a look inside some bearings and see what we see, Spazmastic yeah!!!
[IMG] [/IMG]

The bearing top left is an NTN it has seized as a result of bearing material (rust) building up, put simply not enough grease to weather proof it.

bearing at the top in the middle is an NBK same thing rust as a result of moisture entering the bearing and erosion occurring.

bearing on the top right is an enduro max as you can see the actual balls have rusted and caused this bearing to seize as well.

bearing on the bottom left is an enduro bearing, the problem this time is hardening of the actual grease at the end of its life expectancy and dirt build up.

Bottom middle bearing is another enduro bearing that has seized as a result of the grease coming to the end of its usefulness and also dirt building up.

Last bearing is one of specialized JNK brand and has bad rust and has seized as a result of this.

These are only some of the causes of bearing failure, they do show clearly that rust is a major factor.

Bearing material and design also greasing are the best ways to deal with this and stop it in its tracks.

Can some one stop this shit please.

Kaesae, are you related to Dylan Turvey off bikemagic fame?

Im sorry but there is no way in the world this is not a wind-up.

Whoever invented kaesae is a genius for sure, but it is time for some new material...

Yup - what Dancake said

Someone has some serious time on they're hands inventing such a lunatic!

priceless, absolutely priceless!

As a hardtail rider I for one am hoping for an in depth report on saddle cover material, carried out with equal panache and vim.

w**kers

not just kaesae, the rest of you morons who have the time to bother posting to this moronic shyte

please stop

Kaesae - forget the bearings now. Nobody cares. When we need new bearings we'll just buy some (not from you, obviously).

Please feel free to start an amusing thread on a different topic though.
