Abstract
In a lubricant application system, a prescribed volume of lubricant is transferred from a lubricant discharge port of a prescribed liquid volume discharge device to a rolling element of a rolling bearing in a state in which the lubricant discharge port is positioned directly above and sufficiently close to the rolling element , whereby the lubricant is applied to the interior of the rolling bearing . Further, the application system inspects whether or not a prescribed volume of lubricant is injected from the discharge device for injecting a lubricant into the interior of a rolling bearing . A laser beam L is irradiated between a lubricant discharge port of the lubricant discharge device and the rolling bearing , and a reflected laser beam L reflected by the lubricant when it is discharged from the lubricant discharge port is received by a photoreceptor disposed on the optical axis of the reflected laser beam L , whereby whether or not the lubricant is applied to the rolling bearing is determined based on an output from the photoreceptor
