IKO joint bearing nominal model and accuracy

   The nominal model number of IKO articulated bearings consists of the type designations, dimensions and auxiliary marks. The arrangement is shown below. Example of arranging the nominal model Model number Dimensions SB 20 Joint IKO bearing model Nominal model alignment example 1 Example 2 Model Marking dimension Auxiliary mark GE 30 Bearing model EC 2RS Inner ring inner diameter (30 mm) With gasket Inner ring inner diameter ( 20mm) Accuracy The tolerance of the metric series joint bearing is shown in Table 2.


   GE's allowable tolerances are values before and after the outer ring split. The allowable tolerances for SB, SB...A are the values before the outer ring split and before the surface treatment. The allowable tolerance of GE...EC is the value before the outer ring split. Refer to Table 3 for allowable tolerances of IKO inch series joint bearings. The allowable tolerance of the inner diameter is the value after the surface treatment, and the other allowable tolerance is the value before the outer ring split and before the surface treatment. Sometimes there are some differences from the tolerances due to the surface treatment, but it does not affect the performance of the bearing.
