‧ Applications include M-chassis gearbox area.
‧ 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.
