I've tried to purge the grease out of the suspected contaminated bearing but have no luck, the grease only seems to purge out of the bearing directly behind the nipple and not around the entire area. I tried purging it when warm, the blocked bearing was noticeably hotter to the point where it was uncomfortable to mess around with, so I need to tackle this before the problem worsens.

 

Are there any steps I can take to attempt to clear it without having to dismantling it entirely? Degreaser to clear it out and refill? Blast it with compressed air or jetwash? Sorry if those ideas seem stupid, I don't have a great engineering background!

Compressed air is a much lower pressure than a grease gun. Not sure what you

would do with a jet wash more than wash off the outside surface contamination.

The answer is to grease little and often from the start. By doing that you have the

best chance of keeping the small grease ways clear. Strip and clean is probably a

waste of time as if you have it apart best to put a new bearing in. The bearing

housings in self aligning bearings normally wear so grease will escape from the

low spots. I have come across replacement centres for these but I

would not recommend using them for this reason. Not read all this post so

apologies if I have repeated someone's advice.

Mart. Going back to your original post are you sure that the grease is coming out of the seal? Often it comes out between bearing and housing. I was suprised at your post as skidding of bearings is a very complex subject and we are still learning about the mechanism of this. Lubricating the cage is very important so it is not only about the rollers. True, bearings need space to roll but in a heavily loaded high speed application I would expect excess to be ejected and the bearing to run normally after a short while.

Dirt, vibration, speed, load, all shorten a bearings life so expect to change bearings even if they have

been lubricated correctly. I dont think it is best practice to pump until grease comes past the seal but little and often is probably the way to go.

I think that it is coming out between the cage and bearing rather than at a point in the seal.

 

I've looked up a video of the product Johnny linked, and it looks like the right sort of direction. A £100 tool that I can use again in future might be worth it if it saves me replacing bearings at the cost of parts + labour.
