The SKF 6207-2RS1/C3 sealed deep groove ball bearing provides dependable rotational support in industrial machinery where both contamination protection and greater-than-normal internal clearance are important. Its 35mm bore, 72mm outside diameter and 17mm width follow the standard 6207 mounting dimensions, allowing straightforward identification when replacing an existing bearing. The single row deep groove raceways accommodate predominantly radial loads together with axial loads in either direction, within the bearing's rated capacity. SKF specifies a 27kN basic dynamic load rating and 15.3kN basic static load rating. The SKF Explorer design and sheet metal cage make this bearing appropriate for a broad range of rotating equipment, subject to correct application engineering.
The distinguishing feature is its C3 radial internal clearance, which is greater than the normal clearance provided by the otherwise dimensionally identical 6207-2RS1. This additional initial clearance can help compensate for clearance reductions caused by interference mounting or temperature differences between the inner and outer rings. It is not automatically preferable for every installation: the correct clearance must be selected according to the shaft fits, loads and operating conditions. The 2RS1 rubber contact seals retain the factory grease and help prevent dust and moisture reaching the rolling elements. SKF lists a limiting speed of 6,300rpm for this contact-sealed version. For replacements, check that the original specification requires C3 clearance rather than CN, and do not confuse this designation with grease-specific suffix versions such as /C3GJN.
Typical Applications:
Industrial electric motors requiring C3 internal clearance
Centrifugal pumps and circulation equipment
Industrial fans and ventilation drive systems
Conveyor drives and rotating shaft assemblies
Agricultural and industrial power transmission equipment
