Where the thrusts are approximately balanced, a thrust collar bearing of babbitt metal or a pivoted bearing shoe type, or thrust ball bearings are sufficient to maintain the balance.
The greasy carbon-black from the smoke gets between babbitt metal and rotating shaft and wears off just enough clearance to let the shaft run free and prevent babbitt metal from adhering to the shaft (so long as it is kept lubricated; if it isn't, the bearing can heat up and melt).
Both pure lead and babbitt metal were tried in this system.
