[QUOTE="Trickymissfit, post: 608081, member: 25383"] the days of flooding bearing pockets with lube is dead. The best methods now use oil injection with a very high load capability. They typically use an oil that is fairly light weight (say about 20 weight) that will solidify with contact from air. The idea is that light weight oils penetrate better in the the bearing surface and thaen solidify to stay there. A good quality 10K rpm spindle will only recieve about two drops of oil every 45 seconds at the velocity, or run in a mist condition (soon to be outlawed). Bronze bearings are also being replaced with graphite epoxy compound bearings that seem to last much longer under pressure. With these you only need about 1/10th the lube, and have extremely low compressability with near zero memory while maintaining a near perfect alignment over their life span. gary [/QUOTE]
