The SKF 6206-2RS1/C3 sealed deep groove ball bearing combines the versatile load-carrying properties of the 62 series with greater-than-normal radial internal clearance. Its 30mm bore, 62mm outside diameter and 16mm width provide a compact mounting arrangement for rotating equipment. Deep groove raceways accommodate predominantly radial loads together with axial forces in either direction, within the bearing's rated limits. SKF specifications give a basic dynamic load rating of 20.3kN and a basic static load rating of 11.2kN. The principal distinction from the standard-clearance 6206-2RS1 is the C3 suffix. This increased initial clearance can help compensate for clearance reductions caused by tight shaft fits or differential thermal expansion, but it should be selected according to the application's operating conditions rather than assumed to be universally preferable.
The 2RS1 rubber contact seals retain the factory-applied grease and help protect the raceways against dust, moisture and other contaminants. This is particularly useful in motors and industrial drives where access for regular relubrication is limited. SKF lists a limiting speed of 7,500rpm for this bearing; actual continuous operation must also account for seal friction, applied load, temperature and lubrication conditions. The sheet metal cage separates and guides the balls, while the SKF Explorer design supports dependable performance in appropriately specified installations. During replacement, check the complete designation: the 6206-2RS1/C3 has the same boundary dimensions as a normal-clearance 6206-2RS1, but its internal clearance differs. Mounting forces should be applied to the ring being fitted rather than transmitted through the rolling elements.
Typical Applications:
Industrial electric motors with specified C3 clearance
Centrifugal pumps and motor-driven equipment
Ventilation fans and blower shaft assemblies
Conveyor drives and power transmission systems
Agricultural machinery and rotating equipment
