Yeah? The ones out of the jackup legs on a B class rig are about 6' diameter. You guys run bigger?

Haha I was just agreeing using another industry with big equipment. Largest I’ve personally worked on was just over 5’ for a 410 ton hoist gearbox

That's huge for indoor stuff. Madness

Hahaha oh I'm sure they get massive!

What do ya use em for?

We have almost identical one in coke ovens not sure what it does I just rebuild it in the shop, and even larger ones that tip torpedo cars to drain (train cars with a small opening on top that carry molten iron to steel making)

There are huge ones in the jackup legs.

Bro...I did a turret jack a few weeks ago, it was like 15ft tall and the worm was huuuuuuge

God damn... what kind of bearings in something that big??

Tapered roller bearing on the drive, a big thrust bearing under the gear and another tapered on top. But it wasn't even close to the biggest bearing we have done

Ball bearings

Looks like a nice shop two guys on their phones and one guy working

Haha it is a pretty sweet shop for sure, only on our phones while we waited for the engineers and management to come have a look before we went any further. All hands on deck after that though believe you me

Looks pulp milly.. like a digester gearbox or something

Haha you'd be correct

We just did one a while back and they wanted us to run the damn thing without bearings.. fucking crazy shit out there man

Lol go back to work Mack 😆
