Sundstrand Sauer Danfoss Series 20 Bi Metal Bearing Plates
On picture number 1 you can see smearing all along the surface of the plate. And usually the culprit is there is not enough lubrication. And you can see areas of erosion on the plate also.
On picture number 2 you can clearly see erosion going on. The bronze has been completely eroded away from the steel, you can see around the port holes. This usually happens when air is in the fluid.
On picture number 3 shows the bronze being eroded away by very high pressures and continued use. When noticing friction or noise coming out, you need to stop using the unit.
All these can be avoided by using precaution of your unit, when in use. If you hear something …stop. Don’t just keep going. In the long run it will save alot on repairs.
