The SKF 6217-2RS1/C3 is a sealed single row deep groove ball bearing designed for industrial machinery requiring an 85mm shaft bore and increased radial internal clearance. Measuring 85 x 150 x 28mm, it combines a robust 62 series construction with two rubber contact seals that retain factory grease and help protect against contamination. The C3 clearance provides additional internal space to accommodate clearance reduction caused by interference fits and operating temperature differences. With a sheet metal cage, it is suitable for correctly specified electric motors, pumps, industrial drives and heavy-duty rotating equipment.
The SKF 6217-2RS1/C3 sealed deep groove ball bearing is engineered for large rotating assemblies where shaft support, contamination protection and control of operating clearance are essential. Its 85mm bore, 150mm outside diameter and 28mm width provide a substantial bearing arrangement for industrial equipment. The single row deep groove raceways accommodate primarily radial loads along with axial forces in either direction, within the bearing's rated capacity. SKF specifications give a basic dynamic load rating of 87.1kN and a basic static load rating of 64kN. These figures help engineers assess bearing fatigue life and static loading under the expected duty cycle.
The 2RS1 rubber contact seals retain factory-applied grease and help prevent dirt, moisture and other contaminants from entering the rolling elements. SKF lists a limiting speed of 2,800rpm for this configuration, with actual operating suitability dependent on load, temperature and seal friction. The distinguishing C3 radial internal clearance is greater than normal (CN) clearance and allows for applications where mounting fits or thermal effects reduce the clearance available during operation. C3 does not automatically make the bearing suitable for higher speeds or temperatures; the correct clearance must be selected according to the machinery's operating conditions. When replacing a bearing, confirm the complete 6217-2RS1/C3 designation, as the normal-clearance 6217-2RS1 has the same principal dimensions but a different internal clearance specification.
Typical Applications:
Industrial electric motors requiring C3 clearance
Heavy-duty pump and circulation equipment
Industrial gearboxes and power transmission drives
Conveyor drive shafts and rotating machinery
Large industrial fans and blower assemblies
