Re: Babbitt Bearings in FRC
I used a babbit bearing recently for professional stuff, part of the reason we didn't use a ball bearing was because of the size of the thing.
http://www.mcmaster.com/#6359k22/=10volie that's the bearing we used! ![]() On the last FRC bot I worked on, we used bronze sleeve bearings for the wheel shafts, which were running mecanums! Robot still runs perfect nearly 6 years later |

Was your mom's first name 'Shirley'? This certainly is not a typical soccer mom vehicle.

Re: Babbitt Bearings in FRC
Large stationary engines (if you count ships & trains, semi stationary) typically have poured Babbitt bearings. Most car & motorcycle motor have insert Babbitt bearing. As long as you keep the oil flow, the bearing and shafts do not actually touch. Hydrodynamic layer and all that. MEs spend a lot of class time on that. In the end it is really a bunch of Voodoo.

Re: Babbitt Bearings in FRC
One of the first engines I overhauled was a 1953 Chevy 235, which was the last year they used poured rod bearings. The bearings were still ok, so I just adjusted the clearance using the shims. I was 16 at the time, I think. Those engines used insert main bearings, but they also had shims to adjust the clearance.

I'm a bit of a muscle guy as well. Helped my grandpa build his drag car (1000hp '69 Vega set up for a 250 shot)
