After reading all these replies, I starting to realize why there’s so many bearing problems out there.
well prevention is better than cure.............use good quality bearings in the first place ( check ABEC rating), dont blast with a hose or even worse a pressure washer, no bearing seal will withstand that............ensure seals on hubs/freehub are clean/greased and have not hardened or shrunk ( even better buy well sealed hubs like DT Swiss) and protect seals from the worst of water and mud when riding with a rear mudguard. When cleaning the bike use a stiff brush to clear away any dirt on pivot bearing protection washers which will otherwsie work its way into the bearing. Be aware also that bearings are designed for specific primary forces which are invariably vertical to the bearing orientation..............some sideways ( horizontal) forces are invevitable but it is those forces that create most wear, so you will need to be more vigilant of those bearings if you into hitting berms hard and like doing whips! The most protective cartridge bearing seals also mean most friction but that is not a concern for slow moving parts like pivots so they can be used there.....and they also can be max bearings, but friction is more of a concern in hubs and free hubs , hence lighter contact seals and external sealing of the hub becomes more important.After reading all these replies, I starting to realize why there’s so many bearing problems out there.
After reading this I've decided to never change my bearings.After reading all these replies, I starting to realize why there’s so many bearing problems out there.
After reading this I realise that every few rides it's not so anal dripping a little lubricant onto my pivot bearings and wiping off the excess. On the bike I mean of course.After reading this I've decided to never change my bearings.
I totally agreeGotta be careful heating alloy, doesn't take much detemper it.
At this point Id either pull it out with a slide hammer, or take it to the bike shop
My wife is wise to all those tricksOr take this opportunity to tell the other half it’s new bike time…
Please don’t take this the wrong way but I have been doing that periodically, I read an article about lubing bearings, it’s not a good idea because apparently it attracts dust to the area and it’s impossible to remove the excess from close fitting frame parts, not my words but I see the logic behind it, I’ll just be careful cleaning those areas from now on, I never used a pressure washer anyway but maybe I was a little over pressure with the hosepipeAfter reading this I realise that every few rides it's not so anal dripping a little lubricant onto my pivot bearings and wiping off the excess.

I do that after brushing them each time I clean the bike......because I store my bikes in the house I have to do at least a basic bike clean after every ride!After reading this I realise that every few rides it's not so anal dripping a little lubricant onto my pivot bearings and wiping off the excess.

That’s fair enough mate, carry onI simply stated what I currently do, that's all.
if you are referring to pivot bearings they usually have spacers/seal protectors visible between the bearing and frame. Dirt on those, if left, will work its way between the spacer and bearing seal. Bearing seals are only a comfort fit against the outer bearing shell....not hermetically joined......and it can get past the seal and also cause the seal to rotate when the pivot moves, further weakening the ability of the seal to keep water/dust etc out. The cleaning process has nothing to do with lubricating the bearing itself.............the ball race in the bearing is of course lubricated with grease not oil.Unless you remove the dust seals, you won't manage to get any lubricant into the bearings, you're just dripping it in the general area then wiping it off (unless your bike has grease ports like an intense).
And that's the reason I use my LBS, they have every tool and the know-how to do this job proficiently that you don't lose riding time.Well today I’ve finally been able to start the bearings replacement on my bike, the job itself had been going well until I came to removing the main pivot bearings, the none drive side knocked out easily enough but the drive side bearing just disintegrated into tiny pieces, and to add insult to injury the only piece left in my bike is the outer bearing race, I’ve been on eBay and bought a tool designed to remove the offending piece, I bought from the company I bought the extraction and insertion tools, I’m preying it works but in the mean time my bike is in bits in my workshop
From a personal standpoint I haven’t lost riding time because of my bike, I’ve lost time because of my back, and besides that, most bike shops have a waiting time for repairs, well they do if they’re any good, so there in equals lost riding time, and no I’m not trying to be clever, just pointing out that things rarely get done straight away no matter how good they are.And that's the reason I use my LBS, they have every tool and the know-how to do this job proficiently that you don't lose riding time.
