Questions about bearings and castings for mining industry
Questions about bearings and castings for mining industry
(OP)
Is anyone familiar with the maintenance and life span of "high lead copper alloy" bearings that are used in the mining industry/crushing machinery. Photo of one large bushing attached, but also interested in the "cone crusher" castings.
I am doing some research about the potential life cycle of these wear castings, so perhaps a PM might be the best way to respond.
Thank you in advance.

RE: Questions about bearings and castings for mining industry
I mention this because I see large circular grooves with dead-end side grooves.
Think of grease as just oil with fine silt moving slowly and letting the oil seep away. Once that happens it's tending towards bare metal.
It would be interesting to see the life of a bearing where the grooves were packed with oil saturated felt with a drip oiler to make up for loss.
