The 6808-2RS is a single-row thin-section deep groove ball bearing from the 6800 series, fully sealed on both sides with contact rubber lips that ride directly against the inner ring shoulder. Featuring a 40 mm bore and a highly compact 52 mm outer diameter, it offers an exceptionally slim 7 mm cross-section. This geometry delivers essential weight reduction and space savings without sacrificing the contamination exclusion and long-term grease retention of a fully sealed unit. This combination—a large 40 mm bore within a narrow 52 mm envelope, integrated contact seals, and life-time lubrication—makes the 6808-2RS the optimal solution for precision machinery operating in dusty, damp, or debris-prone environments where standard-sized bearings would be too bulky or heavy.
