Bearing cleaning can be relatively straightforward if you are preparing a new bearing for distribution and need to coat it with an approved lubricant. But bearing cleaning becomes more complicated when you need to remove production lubricants that may be impregnated in the ball bearings, or if production debri is entrapped in the raceways. Some of the lubricants to be removed could be machining oils, stamping fluids, or drawing oils. If the bearings have been returned from the field for rework, the contaminates could also include dirt, burnt or stressed lubricants, and foreign matter. The chosen cleaning fluid should be compatible with all bearing components, and leave zero residue so nothing will contaminate or react with the final lubricant.
Manufacturers who were using AK-225 for bearings should consider:
AK-225AES and AK-225T could be replaced with:
Bearings that were cleaned with AK-225ATE, AK-225ATMS or AK-225TM should evaluate:
