The Set contains:
2 pieces ca. 5x10x3mm Ball bearing
7 pieces ca. 5x10x4mm Ball bearing
2 pieces ca. 10x15x4mm Ball bearing
1 piece ca. 6x12x4mm Ball bearing
10 pieces ca. 4x8x3mm Ball bearing
2 pieces ca. 5x9x3mm ball bearing
The Ball bearings (not flanged) all have one steal sealed and one rubber sealed side.
The rubber sealed side is used for maximum protection from dust and dirt.
The steal sealed side is used for maximum smoothness.
Our recommendation: The rubber sealed side should always be mounted that it faces outwards. Example Hub Bearings: The rubber faces outwards, the stealside faces inwards.
