Single Row Radial Double Shielded Ball Bearing - 608zz
The most common radial ball bearings are single row radial ball bearings, which have an uninterrupted raceway and are suited for radial loads or a combination of thrust and radial loads. Even at high speeds, this architecture allows for accurate tolerances. Metal shields affixed to the outer ring protect shielded bearings on one or both sides (suffixes Z and ZZ, respectively).
The lubrication is retained and foreign matter is prevented by this close clearance labyrinth seal. Steel strengthened rubber seals are tightly connected to a groove on the outer ring in sealed bearings. The sealing lip makes contact with the inner ring.
