Why does the lithium molybdenum disulfide grease melt and leak after being poured into the bearing housing after some time?
Thread Content
The angular bearing housings used with crane wheels were filled with Kunlun brand lithium molybdenum disulfide grease type 3 (with a temperature range of minus 20 degrees to 120 degrees). After one week of operation, they were placed in the workshop and not used any longer. Since it was summer, the temperature in the workshop reached up to 40-50 degrees. Then why did oil start leaking from the seams of the angular bearing housings after half a year?
I’m not sure. The Kunlun brand is pretty decent, but how can one prove there are quality issues?
