The 6812-ZZ is an ultra-thin section single-row radial ball bearing from the metric 6800 series, equipped with dual non-contact pressed steel shields. Featuring a generous 60 mm bore diameter paired with an exceptionally slim 78 mm outer diameter, this component offers an optimal solution for designs requiring substantial shaft support within a highly restricted radial envelope. The "ZZ" configuration utilizes precision-engineered metal plates that guard the internal rolling elements against larger dust particles and debris while safely retaining the factory grease charge, all without inducing the mechanical drag or frictional heat typical of contact rubber seals.
