There are hundreds of thousands of FAG bearings Part numbers, they are indicating different bearing types and structures, if you want to choose a suitable bearing for your industry machines, the first step is to identify the meaning of bearing designation and suffix.
Such as FAG cylindrical roller bearing NU208.M.T5.S1
NU = cylindrical roller bearing, single-row, two lipped outer ring, cylindrical inner ring.
208 = basic bearing series and size designation.
M = machined brass cage, roller guided.
T5 = RBEC-5 tolerance class.
S1 = stabilized for operating temperatures up to 390°F.
Such as FAG deep groove ball bearing 6205.2RS.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
Yakang Bearing Supplies summarized common FAG bearings designation and suffix as following,
