The SKF 62306-2RS1 is an extra-wide, single row deep groove ball bearing designed for industrial equipment requiring a 30mm shaft bore and an extended bearing seat. Measuring 30 x 72 x 27mm, it is 8mm wider than a conventional 6306 bearing, making axial width an important consideration during replacement. Rubber contact seals on both sides retain factory grease and help protect the rolling elements from contamination. Featuring normal radial internal clearance and a sheet metal cage, it is suited to conveyor drives, industrial transmission systems and machinery specifically designed for its 27mm-wide construction.
The SKF 62306-2RS1 extra-wide sealed deep groove ball bearing provides shaft support in industrial machinery designed around a 27mm axial bearing width. Unlike the standard 6306, which measures 30 x 72 x 19mm, this variant occupies an additional 8mm along the shaft while retaining the same bore and outside diameter. The difference affects shoulder positions, spacers and bearing retention, so the two designs are not direct dimensional substitutes. Its single row deep groove raceways accommodate predominantly radial loads and axial forces in either direction within the specified limits. SKF catalogue data gives a basic dynamic load rating of 28.1kN and a basic static load rating of 16kN. The wider construction should not be assumed to deliver higher load capacity than a standard 6306; the actual ratings and operating duty must guide selection.
The 2RS1 rubber contact seals protect both sides of the bearing, helping to retain factory grease and reduce the ingress of dust, moisture and other contaminants. This arrangement is useful in enclosed drive assemblies where routine relubrication is difficult. SKF specifies a limiting speed of 6,300rpm for this contact-sealed version, although continuous operation also depends on temperature, loading and seal friction. Normal radial internal clearance requires appropriate shaft and housing fits to preserve adequate clearance after mounting. When replacing an existing bearing, verify the full 62306-2RS1 designation and 27mm width, particularly where the equipment also uses standard-width 6306 bearings elsewhere.
