Type P press fit headless bushings are the most popluar and least expensive. They offer a wide variety of configurations. Standard I.D.'s are in drill size fractions, letters and numbers. Standard O.D.'s come ground finished ready for insertion or unground enabling customer to finish grind to their O.D. specifications. Standard sizing and ANSI part numbers for P type bushings are listed in the table below.
