FAG bearing model suffix solution (pre-code and post code definition specification)
The
pre-code R is placed directly before the FAG bearing basic code, and
the rest of the code is separated from the basic code by small dots. In the new model specification, replace the small dot with "-"
GS.—— Thrust cylindrical roller FAG bearing race. Example: GS.81112.
K. - Roller and cage assembly. Example: Assembly of thrust cylindrical roller and cage K.81108
R - FAG bearings without separable inner or outer ring. Example: RNU207 - FAGNU207 bearing without inner ring.
WS—— Thrust cylindrical roller FAG bearing shaft ring. Example: WS.81112.
The postcode is located behind the base code. When
there are multiple sets of post codes, they should be arranged from
left to right in the order of the post codes listed in the FAG bearing
code list. Some post ticks are separated from the basic symbol by small dots.
Postcode - Internal Structure
A, B, C, D, E - Internal Structural Changes
Examples : Angular contact ball FAG bearings 7205C, 7205E, 7205B, C-15 ° contact angle, E-25 ° antenna, B-40 ° contact angle.
Examples: cylindrical roller, spherical roller and thrust
spherical roller FAG bearings N309E, 21309 E, 29412E - enhanced design,
FAG bearing load capacity increased.
VH - roller self-locking full-size cylindrical roller FAG bearing
(the roller's complex diameter is different from the same type of
standard FAG bearings).
Example: NJ2312VH.
Postcode - seal and dust
RSR - FAG bearing with sealing ring on one side. Example: 6207 RSR
.2RSR - FAG bearing seals on both sides. Example: 6207.2RSR.
ZR - FAG bearings with a dust cover on one side. Example: 6207 ZR
.2ZR FAG bearing with dust cover on both sides. Example: 6207.2ZR
ZRN - FAG bearing with a dust cover on one side, with a stop groove on the other side of the outer ring. Example: 6207 ZRN.
.2ZRN - FAG bearing with dust cover on both sides, with a stop groove on the outer ring. Example: 6207.2ZRN.
Postcode - FAG bearing dimensions and external structure
DA - Separable double row angular contact ball FAG bearing with double half inner ring. Example: 3306DA.
DZ - cylindrical outer diameter roller FAG bearings. Example: ST017DZ.
K - FAG bearing with tapered bore, taper 1 : 12. Example: 2308K.
K30- Conical bore FAG bearing, taper 1 : 30 . Example: 24040 K30.
2LS - double row cylindrical roller FAG bearing with double inner ring and dust cover on both sides. Example: NNF5026VC.2LS.V - internal structure change, double inner
ring, dust cover on both sides, full-roller double-row cylindrical
roller FAG bearings.
N - FAG bearings with snap grooves on the outer ring. Example: 6207N.
NR - FAG bearings with snap grooves and snap rings on the outer ring. Example: 6207 NR.
N2-- Four-point contact ball FAG bearing with two snap grooves on the outer ring. Example: QJ315N2.
S - FAG bearing with oil groove and three oil holes in the outer ring. Example: 23040 S. Spherical roller FAG bearings with bearing diameter D ≥ 320mm are not marked with S.
X - Dimensions meet international standards. Example: 32036X
Z?? - Technical conditions for special structures. Arranged in order from Z11. Example: Z15 - FAG bearing made of stainless steel (W-N01.3541).
ZZ - roller FAG bearing with two guide ring outer ring.
Postcode - holder and its material
