Each of the layers is a stamped sheet metal layer having a plurality of spaced apart teeth located around a periphery thereof. The teeth in the plurality of connected layers are aligned. At least one of voids, channels, openings, or recesses are located in or between at least some of the layers for receiving and holding lubricating oil. This reduces noise and wear.
