How do I know what size bearings I need for my bike? how to determine the size of bicycle bearings

chenfei Jan 25 20250 comments

The following table is a summary of the size of the bearings required by the bicycle,

1. S or SS stands for stainless steel,

2. ABEC3 stands for bearing accuracy, ABEC1 <ABEC3<ABEC5<ABEC7<ABEC9

The larger the number, the higher the accuracy

3. C3 stands for bearing clearance, C2<C0<C3<C4 ,

Tips: Bearing clearance means the value of displacement of the unfixed ring when it moves against the fixed ring in radial

4. Vmax stands for bearings full of balls, which have greater load capacity than ordinary bearings
