Thrust Bearing Failure - Engine Builder Magazine

Crankshaft thrust faces are difficult to grind because they are done using the side of the grinding wheel. Grinding marks left on the crankshaft face produce a visual swirl or sunburst pattern with scratches, sometimes crisscrossing one another in a cross-hatch pattern similar to honing marks on a cylinder wall.

The only thing you can see in the image is the rear thrust bearing (AXK1226) protruding above the bearing block (just clearing the carriage). Cutting that recess (boring bar) was relatively easy because I could chuck the front of the bearing block against the face of the 3-jaw. The recess for the front bearing (AXK1024) required a fixture.

Rotary Kiln Maintenance Procedures

The roller will move axially until the thrust mechanism inside one of the bearings stops the lateral motion. If the degree of roller misalignment is high, the pressure on this thrust mechanism (either a bearing end cap or a thrust collar) becomes high and increased bearing temperature results.

Grinding Mill Design & Ball Mill Manufacturer

The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20-75 mm. The biggest size is chosen when the mill is used as a primary grinding mill.
