PBS offers a complete line of ball bearing components, retainers and cages for the metal stamping industry. There are two major styles for tooling components, Valcour “D” Series style, and PBS “Precision Style”. These are both completely interchangeable with what is available in the metal working industry today. All PBS ball retainers are made from heat-treated aluminum alloy that combines durability and strength, offering optimum life in high or low speed stamping presses. Quality is assured by constant verification of dimensions, using modern instruments throughout the manufacturing process.
