Which lubrication is best?

Performance demands on inline bearings exceed the capabilities of synthetically based lubricants. A petrolium based lubricant like patented TK Gel has the protective qualities of a grease but the spinning characteristics of light oil.

ILQ-9 K9 Racing Oil is extremely thin but won't put the bearing into boundary conditions at high operating temperatures. An ILQ-9 Pro bearing with K9 lubrication has the longest free spin of any bearing on the market, at 95.76 seconds.
