Type H press fit head bushings are similar to the P type bushing but with a head to resist heavier axial loads.. 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. Note that the "USA length" is under the head while the "metric length" includes the head. Standard sizing and ANSI part numbers for H type bushings are listed in the table below.
