V-Internal layout change; double inner ring; double side with dust cover; full roller double row cylindrical roller bearing. N-outer ring bearing with stop groove. Example: 6207N.NR-outer ring Bearings for moving grooves and snap rings. Example: 6207NR.N2 - Four-point contact ball bearing with two retaining grooves on the outer ring. Example: QJ315N2.S-bearing with smooth oil groove and three smooth oil holes on the outer ring For example: 23040 is. Spherical roller bearings with bearing outer diameter D greater than or equal to 320 mm are not marked with the SX-outer scale conforming to the rules of international regulations. Example: 32036X.Z. . - Special layout skill conditions. Sliding down from Z11. Example: Z15-stainless steel bearing (W-N01.3541).ZZ-Roller bearing with two retaining rings for guiding the outer ring.
(3) Sealed and dustproof RSR-bearing with sealing ring on one side. Example: 6207RSR.ZR- bearing with dust cover on one side. Example: 6207ZR.2ZR-bearing with sealing cover on both sides. Example: 62072ZR.ZRN-bearing side belt Dust cover; the outer ring has a retaining groove on the outer ring. Example: 6207ZRN.2ZRN-bearing with dust cover on both sides; outer ring with stop groove. Example: 62072ZRN.
(4) cage and its information 1) physical cage. A or B is placed after the cage code; A indicates that the cage is guided by the outer ring; B indicates that the cage is guided by the inner ring. F-steel solid cage; Roller guide. FA-steel solid cage; outer ring guide. FAS-steel solid cage; outer ring guide with smooth groove. FB-steel solid cage; inner ring guide. FBS-steel body retention Shelf; inner ring guide, with smooth groove. FH-steel solid cage; carburized and quenched. H, H1-carburized quenching cage. FP-steel solid window cage. FPA-steel solid window type Cage; outer ring guide. FPB-steel solid window cage; inner ring guide. FV, FV1-steel solid window cage; aging; quenching and tempering treatment. L-light metal solid cage; Guide.LA-light metal solid cage; outer ring guide. LAS-light metal solid cage; outer ring guide; with smooth groove. LB-light metal solid cage; inner ring guide. LBS-light metal solid cage; Inner ring guide; with smooth groove. LP-light metal solid window cage. LPA-light metal solid window cage; outer ring guide. LPB-light metal Solid window cage; inner ring guide (thrust roller bearing for shaft guidance). M; M1-brass solid cage. MA-brass solid cage; outer ring guide. MAS-brass solid cage; Ring guide; with smooth groove. MB-brass solid cage; inner ring guide (thrust spherical roller bearing for shaft guide). MBS-brass solid cage; inner ring guide; with smooth groove. MP-yellow Copper solid straight pocket holder. MPA-brass solid straight pocket holder; outer ring guide. MPB-brass solid straight pocket holder; inner ring guide. T-phenolic laminated tube solid cage; Body guide. TA-phenolic laminate tube solid cage; outer ring guide. TB-phenolic laminate tube solid cage; inner ring guide. THB-phenolic laminated tube pocket holder; inner ring guide. TP-phenolic laminated tube straight pocket holder. TPA-phenolic laminated tube straight pocket holder; outer ring guide. TPB-phenolic laminated tube straight pocket holder; inner ring guide. TN-engineering Plastic mold holder; roll guide; additional numbers indicate different materials. TNH-engineering plastic self-locking pocket holder. TV-glass fiber reinforced polyamide Solid cage; steel ball guide. TVH-glass fiber reinforced polyamide self-locking pocket type solid cage; steel ball guide. TVP-glass fiber reinforced polyamide window type solid cage; steel ball guide. TVP2-glass fiber reinforcement Polyamide solid cage; roller guide. TVPB-glass fiber reinforced polyamide solid cage; inner ring guide (thrust roller bearing for shaft guidance). TVPB1-glass fiber reinforced polyamide solid window cage; shaft guide ( Thrust roller bearing). 2) Stamping cage J-steel stamping cage. JN-deep groove ball bearing riveting cage. 3) Retainer change is added after the cage code; perhaps the number inserted in the cage code center; Indicates that the cage layout has changed. These numbers are only used for transition periods; for example: NU1008M1.
.5) without cage bearing V-full rollover bearing. Example: NU207V.VT- full complement roll bearing with blocking ball or roller. Example: 51120VT.
.6) Public service level (including scale accuracy and rotation accuracy)
P0-public service level conforms to level 0 of the international standard ISO rule; the code is omitted; does not indicate that the .P6-public service level conforms to the international standard ISO rule level 6. P6X-public service level conforms to the international standard ISO rule 6X cone Roller bearings. P5 - public service level meets the international standard ISO rules of level 5. P4 - public service level meets the international standard ISO rules of level 4. P2 - public service level meets the international standard ISO level 2 (excluding tapered rollers Bearing). SP-scale accuracy is equivalent to 5; rotation accuracy is equivalent to 4 (double row cylindrical roller bearing). UP-scale accuracy is equivalent to 4; rotation accuracy is higher than 4 (double row cylindrical roller bearing) .HG-scale accuracy is equivalent to 4; rotation accuracy is higher than 4; lower than 2 (spindle bearing).

| The reason why the bearing raceway sound occurs and the use of the characteristic variable speed bearing should be emphasized. The adjustable heart of the spherical bearing with the seat The difference between the additional dynamic load and the additional static load of SKF bearing is different. |
