The post code indicates the supplementary code added after the basic code of the bearing when the FAG bearing structure shape, size, seal, cage, tolerance, clearance, heat treatment, packaging, technical requirements, etc.——Thrust cylindrical roller FAG bearing race. S2-FAG bearing ring has been subjected to high temperature tempering treatment, and the working temperature can reach 250℃.
MP-brass solid straight pocket cage. See the table below for the arrangement rules of FAG bearing codes. S is not marked for spherical roller FAG bearings with bearing outer diameter D≥320mm. S1-FAG bearing ring has been subjected to high temperature tempering treatment, and the working temperature can reach 200℃. The front code means that FAG bearing parts are placed before the basic code. Example:Wholesale roller bearing F80-FAG bearing inner and outer diameter tolerance and radial clearance compression.2ZRN-FAG bearing with dust cover on both sides, with stop groove on the outer ring.
LBS——Light metal solid cage, inner ring guide, with lubrication groove.2RSR. FAG bearings configured in pairs or groups must be packed together for delivery, or marked as a pair. P2-Tolerance level conforms to level 2 specified by the international standard ISO (excluding tapered roller FAG bearings). C0——The clearance accords with the 0 group stipulated by the standard, omitted in the code, not indicated. C4-Clearance meets the standard requirements of 4 groups, greater than 3 groups. Example: WS. K3-Two sets of deep groove ball FAG bearings are installed back to back without clearance (O-type installation). Example: K20×25×40FZW.
TPB-Phenolic laminated cloth tube straight pocket cage, inner ring guide.ZW——Double row needle roller and cage assembly. TP——Phenolic layer tomb cloth tube straight pocket holder. SP——The dimensional accuracy is equivalent to level 5, and the rotation accuracy is equivalent to level 4 (double row cylindrical roller FAG bearings). TVPB1-glass fiber reinforced polyamide solid window cage, shaft guide (thrust roller FAG bearing). Example: 6207RSR.
Post code—Special technical conditions KDA—Splitinnerring/; Split inner ring K—Taperedbore tapered hole 1:12K30—Taperedbore tapered hole 1:30N—circularintheouterringforsnapringS—Lubricatinggrooveandboresintheouterring ‘S’ suffixed in the new E1 All in the series have been cancelled! The outer ring oil groove and oil hole have now become standard equipment.K5.A120. JN-deep groove ball FAG bearing riveted cage. S-FAG bearing with lubricating oil groove and three lubricating holes in the outer ring. Example: 6213. Example: QJ315N2. Mainly refers to deep groove ball FAG bearings with inner diameter d≤60mm.
