These are rubber sealed ball bearings, which offer smooth rotation, great precision of attachment and even simplified maintenance.
- 1280 (8x12mm) Sealed Ball Bearings x2
- Applications include TT-02 chassis front/rear differential gears and F104 chassis ball differential.
- Using ball bearings in place of plastic and metal bearings gives more efficient rotation and better parts setup.
- These ball bearings employ blue rubber seals rather than metal ones – this allows you to open up the bearings to clean and work on them. Blue rubber seals also vastly help in the prevention of debris entering the race roller.
- Low-viscosity oil is used to lubricate the internal workings.
- Periodically perform maintenance such as adding oil; after crashes, checking bearing movement is recommended. |
