A guide bearing assembly for a can bodymaker, said bodymaker including an elongated ram body, a crank arm, carriage assembly, and a die pack defining a passage, said carriage assembly including a body with a ram coupling and a crank coupling, said crank arm coupled to said carriage assembly body crank coupling, said ram body coupled to said carriage assembly body ram coupling, said guide bearing assembly comprising:
a first guide bearing assembly including a saddle and a journal channel; and
a second guide bearing assembly including a saddle and a journal channel,
wherein said journal channel of said first guide bearing assembly is disposed apart from said journal channel of said second guide bearing assembly such that said body of said carriage assembly is disposed therebetween,
wherein said saddle of said first guide bearing assembly and said saddle of said second guide bearing assembly are structured to orient said ram body with said die pack passage,
wherein each saddle includes a number of thrust pad assemblies,
