Also where can I get enduro bearings??

 

 

I know its friday and thats not what this post is about 

 

 

Thanks !

Enduro bearings are distributed by a crowd in PMB. Will only supply bike shops. I would buy from bearing man if I could but they cannot get me cannondale headset bearings and the bike shop wants over R300 each. Enduro bearings are good though but I would prefer to be able to get direct.

Kay I'll bite...

Regarding the video... Get any old bearing with the races and balls not completely destroyed. then strip out any lubrication and get it squeaky clean. Now spin it up. It will spin surprisingly well. Perhaps not as well as the voodoo bearing in the video, but well enough to bring the point across.

A freely spinning bearing isn't necessarily a good indication of quality.

 

A much better way of establishing the quality of bearing is to look its ABEC rating (higher the number, the tighter the tolerances, the better the quality) or if you're getting balls only find out their Millions of an Inch Rating (the lower the number the better. Typically Shimano XT ships with 25 rated balls, I prefer running balls with a Millions of an Inch Rating of 5. The races on my XT axles just last better.)

There are so many bearings and applications that there is not a common standard to compare.  Enduro use the ABEC scale which measures the tolerances of the bearings and race.  It does not measure smoothness, heat limits, material, lubricants seals etc.  ABEC 3 is considered good enough for bikes, with some component manufacturers using ABEC 5 in their hubs.  ABEC 7 are used in sports like competition skate boarding but are not easily obtainable and are pricey.  ABEC 9 is the highest standard.

 

Shimano grade their loose balls on the maximum size of imperfections on a ball's surface.  25 micron imperfection are Grade 25 and 5 micron are Grade 5.  The cheap no name caged balls can run much higher (100+).

 

Just be guided by logic.  Well known reputable brands are likely to cost more than unknowns but most likely will outperform the cheapies on average.

Plenty of info online. I've posted a couple of articles, videos etc, but if you guys are interested I can put some details up to give a breakdown of the differences?

Please   :thumbup:

I believe enduro bearings are full complement bearings, that have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. i.e good for suspension.

If it's not on the hub it's not "online".... To hubbers Google etc doesn't exist  :ph34r:

Enduro are not that much more expensive compared to good quality bearings that you get from BMG like NSK and SKF.  Try to stay away from the Chinese cheapies though.

 

For suspension pivots you will want to use max compliment bearings, which is why Enduro offers their MAX line of bearings for this purpose.  Then for the other applications I would look at getting as high an ABEC rating as possible within budget, but still high quality.  Here I try to get NSK if available, then look to see what Enduro has.  The price difference is usually not more than 15% anyway.  Also keep in mind the rating of the seal.  I used 2 NSK bearings with an LLU seals in my hubs.  They usually offer the best protection against water and mud.

 

If you really want to, you could also open the bearings up and then replace the grease with the best quality marine grease you can find.  However, the lubrication in the bearings becomes a contentious point for the downhill racers, who will want the least amount of resistance in their bearings.

 

EDIT:  NTN are also a good quality brand.
