.3) The cage is used to indicate the guiding method of the cage in the bearing; the letter A or BA may be added after the rear code of the cage to indicate that the cage is guided by the outer ring, and B indicates that the cage is guided by the inner ring. Guided by a tumbler. F steel or a unique cast iron solid cage. J Sheet metal stamping cage. M Light alloy solid cage. MP brass solid cage. P Glass fiber nylon 6. 6 mould retainer. TN Engineering Plastic molded cage. Y copper plate stamping cage. V Full roller bearing (without cage). VH Full complement roller bearing (cylindrical roller bearing) consisting of non-displacement roller assemblies. (3) Others Characteristics 1) Public service level / CLN is equivalent to ISO public service level 6X; used for metric tapered roller bearings (width reduction is common). /CL0 is equivalent to ISO0 level public service; used for inch tapered roller bearings. /CL3 Equivalent to ISO3 level public service; used for inch tapered roller bearings. /CL7A tapered roller bearings conforming to differential bearing specifications. /CL7C fit differential bearings are equipped with unique specifications of tapered roller bearings. /P4 scale and Rotation accuracy meets ISO4 level public service (than P5 Accuracy). /P4A Scale accuracy meets ISO4 level public service; rotation accuracy is equivalent to AFBMA specification ABEC9. /P5 scale rotation accuracy conforms to ISO5 level public service (accuracy is higher than P6). /PA9A scale and rotation accuracy is equivalent to AFBMA specification ABEC9 The /PA9B scale accuracy is equivalent to the AFBMA specification ABEC9; the rotation accuracy is higher than PA9A. /SP scale accuracy is about P5; the rotation accuracy is about P4. /UP scale accuracy is about P4; the rotation accuracy is higher than P4. 2) Bearing The clearance/C1 clearance fits the normal rule of the group; the clearance is less than 2 groups. /C2 The clearance fits the standard rule 2 groups; the clearance is less than 0. /C0 The clearance fits the norm of the rule group 0; Off; does not indicate that the /C3 clearance fits the three rules of the norm; the clearance is greater than 0. /C4 clearance fits the four rules of the norm; the play is greater than three. /C5 clearance fits the five rules of the rules; The clearance is greater than 4 groups. When the clearance code is combined with the bearing public service code P4; P5 or P6; the clearance code C can be omitted. Example: P6+C2=P62 3) Unique skill demand. /Q Best internal A few layouts and appearance roughness (for tapered roller bearings). /Q66 Oscillation level is less than the general specification; oscillation peak Usually less than level specifications / QE5 unique fit with the motor specification;. And the rotation accuracy of the scale P6. Very low noise. /QE6 fits the motor specification; low noise. 4) Bearing equipment. /DB Two pairs of single row deep groove ball bearings; single row angular contact ball bearings or single row tapered roller bearings with back to back method paired devices. DB The following figures indicate the axial clearance or the preload of the device. A light preload (angular touch ball bearing). B Preload is larger than A (angular touch ball bearing). C Preload is larger than B (angle touch Jack joint).
