Explanation about the C3 group of big clearance: internal clearance size in running of rolling bearing (such as 6208) has great influence on bearing performance,such as fatigue life, vibration noise, temperature rise and so on. Some machineries need large clearance C3 group, so it's very important to choose bearing internal clearance for those structures of bearings determined. Definition of clearance is the amount of gap among bearing inner ring, rolling body and outer ring, that is amount of movement when fixing one of the bearing inner ring or outer one, then move the other ring up and down or move around. Move amount of the radial direction and axial direction are named as radial clearance and axial clearance respectively. Generally, when testing clearance, stipulated test load of bearing is needed, and then to test clearance, so the measured value is greater than the theoretical value.
The clearance value stipulated by NSK bearing has common clearance value CN, applicable to the general conditions of use. On this basis, small side is according to C2,C1 sequence, which in turn decreasing clearance value while big side is according to C3 C4 C5 order, so as to increase the clearance value. So-called the general conditions of use, it is to point to the bearing stands the load below common one whose inner ring uses interference installation.
