Good ones are - but these days thanks to the 3D printer & DIY CNC crowd you can get surprisingly cheap ones too that tend to be way better than they have any right to be. Seen a few folks upgrade old or cheap lathes & mills with them. Quote Link to comment Share on other sites More sharing options...

Ed Poore Posted August 24, 2023 Share Posted August 24, 2023 I guess your kind of ballscrew is made up of huge steel wheels rather than tiddly ball bearings. Quote Link to comment Share on other sites More sharing options...

Popular Post Stellaghost Posted November 13, 2023 Author Popular Post Share Posted November 13, 2023 Quite a few of us will have changed big end shells, not too bad a job, so I thought I would post this white metal bearing change ( think massive shells ) Old bearing had failed causing white metal to wipe, my foot to give perspective New one to be installed, these are supplied round and oil lead has to be scraped in on the white metal surface, hence the need for bearing scrapers ( I know this makes you happy @Nonimouse ) this is what it is getting fitted onto lifted to allow bearing to be slid out bearing slides in here trunnion that sits on it bearing half weighs around a ton, ring in the middle is an oil lifter regards Stephen 5 Quote Link to comment Share on other sites More sharing options...
Snagger Posted November 13, 2023 Share Posted November 13, 2023 Wow! Impressive machinery. The oil lifter - is that just like a set of buckets set into the collar that simply scoop oil up at the bottom and pour it as they pass over the top?

Steve It is a cement mill, clinker and gypsum in one end, ground into cement through two Chambers, first one containing a mix of 70 upto 90mm balls, second chamber is three times longer containing a mix of 17mm to 20mm balls for the finishing grind. Total weight including shell around 150 tonnes Regards Stephen 6 Quote Link to comment Share on other sites More sharing options...

It was down around 8 days, you never really recover the lost output because increasing the mill throughput would affect quality. You just have to have full storage silos to cover unplanned outages Regards Stephen 3 Quote Link to comment Share on other sites More sharing options...
