The Original Shellplate Bearing Kit. We sell shellplate bearing kits for Dillon Precision Reloading Press. We have several kits for the 550, 650, 900 and 1050 series of Dillon presses. Use the categories at the left to see what is available for specific press. Our Phenolic Low Mass Detent Ball is super hard, smooth and lightweight. It's approximately 7 times lighter than the factory steel ball and every bit as tough. The ball has less momentum when it locks up with the shellplate. The material also absorbs vibrations much better than the steel ball. This ball is highly abrasion resistant and will not be cut or scared by the shellplate. These are industrial grade and used when strength and abrasion resistance is required. We gave the oil-lite washer a go, results were underwhelming. if you bought one we will replace it with a needle bearing free of charge. All of our items are listed as buy it now and auctions.
