The 6012 2RS C3 PBF is an industrial ball bearing made from bearing steel and manufactured by PBF. It has an internal diameter of 60mm, an outer diameter of 95mm and a width of 18mm. It is a deep groove ball bearing, meaning it has a deep internal groove in which a metal ball is held in place, allowing it to rotate within the bearing. It is double-sealed against dust and liquids and also has a reinforced rubber seal. The metal ball is zinc-plated for corrosion resistance. Finally, it comes with the C3 clearance which is a higher level of clearance than normal bearings, allowing it to spin more freely.
