I have a pneumatic cylinder rod end 'rose bearing' (ie spherical bearing) thoroughly stuck on the shaft that it moves. I've managed to unscrew the pneumatic cylinder rod so just the rose bearing remains in situ. It is on a 20mm stainless shaft and the ball of the bearing is tightly up against a shoulder. The ball itself has rusted and is totally jammed to the shaft yet still moves as a bearing. I can put a standard puller on the ball housing, but it seems to be made of softish alloy and I think applying more pressure than I already have will break it. I've applied gentle heat and even not so gentle heat to no avail. Scared to break it as I've not found a source of replacements (20mm shaft and 20mm 2.5mm pitch right hand female thread). Short of making a special puller (which is my next move) do the panel have any innovative solutions for getting it off?
