Abstract
An arrangement in which respective roughnesses are defined for orbital grooves of inner and outer rings and a surface of rolling members which are constituents of a rolling bearing and in which their conditions of contact are controlled whereupon a minimum amount lubricating oil is adhered at a strong bonding force to thereby obtain a condition in which lubricating oil is continuously interposed at mutual contacting portions of the inner and outer rings, the rolling members and a cage to thereby enable favorable sliding properties and remarkable restrictions in generation of dust.
