SKF 6208-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 40x80x18mm

The SKF 6208-2RS1 sealed deep groove ball bearing is engineered for 40mm rotating shafts where reliable radial load support must be combined with a compact, protected bearing arrangement. Its single row ball and raceway design also accommodates moderate axial forces in either direction, within the bearing's rated capacity. SKF specifies a basic dynamic load rating of 32.5kN and a basic static load rating of 19kN, providing important values for service-life calculations and load assessment. Compared with the narrower 6008 series, the 6208 offers a larger bearing cross-section and greater load capacity, making it useful for machinery with more demanding shaft loads where housing space permits.

The 2RS1 rubber contact seals protect both sides of the bearing, retaining factory grease while restricting the entry of dust, dirt and moisture. This helps reduce maintenance demands in enclosed motor, pump and drive assemblies. SKF specifies a limiting speed of 5,600rpm for this sealed configuration, although actual operating conditions must also account for temperature, loading and contact seal friction. Normal radial internal clearance distinguishes this version from the 6208-2RS1/C3, which provides increased internal clearance for appropriately specified fits or thermal conditions. When replacing an existing bearing, confirm the full designation and consider shaft tolerances, housing alignment and the required operating clearance.
