Abstract : The patent describes a low heat generation roller bearing having inner and outer races. Oil is applied to the surface where the rollers and inner race contact by means of an oil jet nozzle. Centrifugal force and rotation of the rollers, forces the oil around the rollers to the outer race. Radial bores extend through the outer race and connect with one or more circumferential grooves to collect and aid in transmission of oil from the outer race. A path is provided to return the oil to an oil sump for scavenging back to an oil supply tank.
