The SKF 6207-2RS1/GJN sealed deep groove ball bearing supports 35mm rotating shafts in equipment where load capacity and lubricant specification are both important. Its single row deep groove construction accommodates predominantly radial loads together with moderate axial forces in either direction. SKF Explorer specifications include a basic dynamic load rating of 27kN and a basic static load rating of 15.3kN, providing useful reference values for bearing life and load calculations. The 62 series cross-section offers greater load capacity than the slimmer 6007 series, making it suitable for appropriately designed motor, pump and transmission assemblies where the available housing space permits.
The defining feature of this variant is its GJN polyurea-thickened grease, specified for a nominal grease temperature range of -30°C to +150°C. This is a lubricant specification rather than a guarantee that the complete bearing assembly can operate continuously throughout that range. Double 2RS1 rubber contact seals retain the grease and help prevent contamination, reducing routine relubrication requirements. The published limiting speed for the sealed bearing design is 6,300rpm, although loading, temperature and lubricant conditions influence actual suitability. Normal radial internal clearance must be checked against shaft fits and thermal expansion. When replacing a bearing, match the GJN suffix if the equipment manufacturer specifies this grease.
Typical Applications:
Industrial electric motors requiring specified grease
Ventilation fans and blower shaft assemblies
Industrial pumps and circulation equipment
Conveyor drives and mechanical transmission systems
Enclosed machinery with limited lubrication access
