Revolution Design 3149-2 - Tamiya VQS 2020/Avante - Ultra Bearing Set (22 pieces)

The Set contains:

4 pieces ca. 7x16x5mm Ball bearing
10 pieces ca. 5x11x4mm Ball bearing 
4 pieces ca. 4x8x3mm Ball bearing
2 pieces ca. 3x8x3mm Ball bearing
2 pieces ca. 1.5x6x3mm Ball bearing

The Ball bearings 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.
