The SKF 6209-2RS1/C3 sealed deep groove ball bearing is designed to support rotating shafts in industrial equipment where both load capacity and operating clearance are important. Its 45mm bore, 85mm outside diameter and 19mm width conform to the 6209 dimensional series, making it suitable for bearing positions specified for this size. The single row deep groove construction accommodates primarily radial loads together with axial forces acting in either direction, within the bearing's rated limits. SKF Explorer specifications give a basic dynamic load rating of 35.1kN and a basic static load rating of 21.6kN. These ratings provide a basis for evaluating bearing life and selecting a suitable component for machinery subject to continuous rotation or varying mechanical loads.
The 2RS1 rubber contact seals retain the factory-applied grease and help protect the raceways from dust, moisture and other contaminants, reducing the need for routine relubrication. SKF lists a limiting speed of 5,000rpm for this sealed bearing, with actual operating suitability dependent on load, temperature and seal friction. Its defining feature is the C3 radial internal clearance, which is greater than normal (CN) clearance before mounting. This can help accommodate clearance reductions caused by tight shaft fits or temperature differences between the inner and outer rings, but it should only be selected where the application requires it. A sheet metal cage supports the rolling elements. When replacing a bearing, check the complete designation because the normal-clearance 6209-2RS1 is not necessarily an appropriate substitute.
Typical Applications:
Industrial electric motors requiring C3 clearance
Centrifugal pumps and fluid circulation systems
Conveyor drive shafts and pulley assemblies
Industrial gearboxes and power transmission equipment
Agricultural machinery and mechanical drive units
