Ceramic Ball Bearings

ROCHE ceramic ball bearings are made from pure silicon nitride material that are 60% lighter in weight and 7 times harder than steel. Friction is reduced to near zero, so your car acceleration and top speed will be even better. Both sides of the bearings feature low contact labyrinth type rubber seals which after a few runs you will notice get even smoother when the bearing do a matching groove on the inner seal. You can always remove the seals and relubricate the sealed bearings with dedicated ball bearing oil.
