"tiny balls equal higher contact point pressures... no way around that factor." maddog34
This! The load capacity of a ball bearing is geometrically related to its diameter. Double the ball count with half their diameters and you lose 50% of the load capacity. Add in 3X the initially stated life span and the wear rate sounds more typical. Andy
