6805N-2RS-HC-LC HYBRID CERAMIC LOW CONTACT (CAMPAGNOLO ULTRA TORQUE)
Low contact seal and low viscosity grease both aimed to reduce friction. They have been made distinctive by there’re yellow seals.
Hybrid ceramic bearings are the most common type of ceramic bearing, constructed of stainless steel inner and outer races with ceramic Si3N4 balls in place of steel ones.
Hybrid ceramic bearings have various advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, higher accuracy, lower friction and low heat generation, low thermal expansion.
