Abstract: A lubrication system for an enclosed rolling element bearing may be achieved through a channel drilled through the outer race of the bearing and the outer surface of the bearing housing. The channel provides a direct path for the injection of lubricant via a grease gun or syringe to reach the rolling elements within. The lubrication system can be adjusted to assure lubricant does not leak from the channel with the addition of a tube or hollow screw or combination of the two along the entirety of the channel.
