TIMKEN BEARING part number system

Most Timken symbols are die stamped as part of the bearing number, however there are many cases where our automotive and industrial applications require special considerations in bearing designs and tolerances. To be certain future cone and cup replacements are made correctly, the factory supplements imprinted identifications with electric penciling to add prefixes and suffixes to the imprinted part numbers. These additional markings become important to the user for proper bearing identification and replacement.

FAG bearing part number system

How to read FAG part numbers:

EXAMPLE: 6203.2RS.T5.C3.L19

6203 = basic bearing series and size designation.
.2RS = two molded rubber seals.
.T5 = ABEC-5 tolerance class.
-C3 = AFBMA internal radial clearance.
.L19 = Mobil 28 grease, MIL-G-81322.

EXAMPLE: NU205.M.T5.S1

NU = cylindrical roller bearing, single-row, two lipped outer ring, cylindrical inner ring.
205 = basic bearing series and size designation.
.M = machined brass retainer, roller guided.
.T5 = RBEC-5 tolerance class.
.S1 = stabilized for operating temperatures up to 390??F.
