Why are your bearings C3? - Bearing KingWhy are your bearings C3? Internal clearance being C3 means that the bearing has room for expansion if needed between the races of the bearing, whilst holding the outer ring and moving the inner ring in a radial movement you will detect a little amount of play between the two ringsUnderstanding bearing internal clearance - Machine DesignBearing manufacturers denote radial internal clearance groups as “Normal,” “greater than Normal,” (C3 suffix), “less than Normal” (C2 suffix), and so forth
Bearing Internal Clearance and Preload - NTN GlobalC3，C4. 8.2.1 Criteria for selecting bearing internal clearance. A bearing's life is theoretically maximum when operating clearance is slightly negative at steadywhy the C3 bearing is commonly used in MOTOR - Electric motorsHELLO MY QUESTION IS THAT WHY C3 bearing is used in High or low voltage induction motors. Why not normal or C1 or any else. thanksInternal clearance Bearing internal clearance (fig. 1) is defined as the  Sufficient internal clearance in a bearing during operation is important.
