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.
