After a year and a half of design development, we have provided a simple and effective solution. The R.M. King’s proprietary bearing KJD8804G has grease holes which allows grease to easily flow to the bottom of the bar. In addition to the grease holes, this bearing is a caged needle bearing.  This is higher quality and more reliable than the failure prone full-compliment bearings. Finally, these bearings are manufactured by INA, who is well known in the bearing industry for their superior quality.  The bearings extend life of the bar parts, save money and decrease downtime in the future. The Grease Kit is automatically installed as part of an R.M. King Company overhaul.

Grease will take the path of least resistance as it flows through the machine.  As the grease is pushed down the bar, pressure is increased as the grease passes through the first bearing.  With each consecutive bearing, the pressure is increased further. By the time the grease gets past to first few bearings, the pressure required to pass the remaining bearings becomes greater then the pressure required to pass the thrust sleeve and thrust washer.  This results in the grease being pushed out the top of the bar. It is a common misperception that when grease comes out the top of the bar, the bar is full of grease. The holes in the grease bearings allow grease to flow through at a lower pressure.  The result is easier flow for grease to reach the bottom of the bar.
