They're synthetic sealed ball bearings, which offer smooth rotation, great accuracy of attachment in addition to simplified upkeep.
• 1280 Sealed Ball Bearings x2
• Applications include TT-02 framework front/rear differential gears and F104 framework ball differential.
• using ball bearings instead of plastic and metal bearings provides more effective rotation and better components setup.
• These ball bearings utilize blue synthetic seals rather than steel individuals – this permits one to start the bearings to wash and use them. Blue synthetic seals moreover greatly aid in the prevention of debris going into the competition roller.
• Low-viscosity oil is useful to lubricate the internal workings.
• periodically perform maintenance like adding oil; after crashes, checking bearing motion is recommended.
