SPECIAL BEARING NOMENCLATUREA special bearing is represented by either two or three numbers, a letter or group of letters, and two numbers.
EXAMPLE: OOOXOO
The first group of numbers can be read in inches with a decimal point before the last number, and represents any bore size within that tenth of an inch. The letter or group of letters further describe the bearing according to the code listed below. The last two numbers are sequential numbers used to designate a difference between other special bearings with the same numbering and lettering description.
