[TPR] Grooved Main Bearings

[russell fulp]

O.K. guys there is a reason why nobody makes a fully grooved bearing but that takes in to play,bearing speed,surface diameter,surface width,R.P.M. as well as centrifical forces . Federal Mogul makes a 3/4 groove main for performance applications . You see every time an internal combustion engine fires it actually bends the crank,not much have you but it does happen ! The downward force that is applied as the spark plug fires is how a engine is rated as far as Horsepower & Torque (so to speek) That is also the reason why the rod bearing as well as the main bearing is not grooved fully ! It requires that added bearing surface to put up with the load .It actually has very little to do with lubrication .There are a ton of other factors that come into play here but that is the general idea .
