Clearance: the amount of clearance between roller and ring.
Accuracy: refer to the bearing size accuracy and rotation accuracy.
The precision of the bearing has a certain influence on the accuracy of the clearance, has no effect on the size of the clearance.
Clearance size is set before delivery.
The radial internal clearance code: NSK, for example the C2 < < C4 C3 < < CN C5 CN (
Some factory called C0)
Is the standard clearance, called big clearance is greater than the standard clearance, called small clearance is less than the standard clearance.
CM clearance: motor is special clearance, clearance value between CN and C3, quantity is small.
MC1 < MC2 < MC3 ball bearing (< MC4 < MC5 path
Miniature bearing)
Radial internal clearance.
It is a standard MC3 clearance.
E and EN: magneto bearing radial internal clearance.
The precision of different bearing can have different clearance.
For example: the code is about precision code P6 and clearance code C3 address together.
/ C1 -
-
1 set of the clearance, clearance is less than 2 groups.
/ C2 -
-
Clearance conform to the standards stipulated by the two groups, group windage is less than 0.
/ C0 -
-
Clearance conform to the standards stipulated by the 0 group, code omitted, don't say.
/ C3 -
-
Clearance conform to the standards stipulated by the three groups, group clearance greater than 0.
/ C4 -
-
Clearance conform to the standards stipulated by the four groups, clearance is greater than three groups.
/ C5 -
-
Clearance conform to the standards stipulated by the 5 groups, clearance is greater than the four groups.
