Machining of self-lubricating bearings is like machining of light metals (similar to aluminum). To avoid sealing of the porous surface it is recommended to use sharp tools made of tunsgten carbide and to follow the machining instructions described in this flyer. Grinding is not recommended. | Re-impregnation of bearings after machining. After machining immerse the parts in a bath of oil at 80 degrees C for one hour. Use oil of the same grade as the initial impregnation (MT 100). Let bearing cool down while immersed in the oil bath |
