SKF 6009-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 45x75x16mm

The SKF 6009-2RS1/C3 sealed deep groove ball bearing provides rotational support where machinery requires a 45mm shaft bore without the larger outside diameter of heavier bearing series. Its 45 x 75 x 16mm dimensions offer a relatively slim radial section, making housing compatibility an important consideration. The single row deep groove raceways accommodate predominantly radial loads together with axial forces in either direction, within the bearing's rated limits. SKF specifies a basic dynamic load rating of 22.1kN and a basic static load rating of 14.6kN, providing reference values for bearing-life calculations and load assessment. The SKF Explorer classification identifies this as part of the manufacturer's enhanced-performance bearing range.

The distinguishing feature is its C3 radial internal clearance, which is greater than the normal clearance of a standard 6009-2RS1 bearing. This additional initial clearance can help compensate for reductions caused by interference mounting and temperature differences between the inner and outer rings. However, C3 is not automatically preferable for every application; the required operating clearance depends on shaft fits, housing tolerances, loading and operating temperature. The 2RS1 rubber contact seals retain factory-applied grease and help exclude moisture and particulate contamination, reducing routine lubrication requirements. SKF lists a limiting speed of 5,600rpm for this sealed configuration, although sustained operation must also account for seal friction and thermal conditions. Confirm that the application requires C3 clearance before replacing a normal-clearance bearing.

Typical Applications:

Electric motor assemblies specified for C3 clearance

Industrial centrifugal pumps and circulation equipment

Ventilation fans and rotating drive systems

Compact conveyor and material handling machinery

Industrial transmission shafts with interference fits
