SLEW RING WITH GEAR
SLEW RING WITH GEAR
(OP)
Hi,
I have this gear assembly with a freely rotate inner ring. In between is a bearing. Need to open up the ring because it is jammed. Anyone ever use similar parts before?



Any idea how to open up the ring? I suppose we need to press from top (first figure).

RE: SLEW RING WITH GEAR
if you have a slew bearing alike this one:
DON'T press. There's a plug or sthg somewhere where you can open up & get the balls out of the raceway. However, "jammed" might mean that the bearing is seriously damaged (broken ball, deadlock from debris) and the opening will not be possible by normal means. In general such maintenance should be left to a specialized company.. which might also be able to provide a replacement, just in case.

that's really helpful. we found a small pin for the ball bearing doorway on inner side. now still thingking how to take out the doorway. we managed to take out the pin already.
by the way, do you know what is the name for the top and bottom seals?

Maybe a good soaking in a rust remover?

Even the doorway for the bearing is unable to be open.
So the plan would be to cut the inner ring and make a new one or just buy a new set.

Same unit from China is USD300++. Just for info only. The material could substandard.

Rotis, PSL, Rollix.
i wouldn't source it from china though.
it seems that it doesn't have upper seals though. I think it's probably a write-off, if you haven't removed them yourself just prior to taking the picture.
