The SKF 6215-2RS1/C3 is an SKF Explorer single row deep groove ball bearing designed for industrial machinery requiring a 75mm shaft bore and increased radial internal clearance. Measuring 75 x 130 x 25mm, it features rubber contact seals on both sides to retain factory grease and help protect against contamination. The C3 clearance provides greater internal space than a normal-clearance bearing, making it suitable for applications where interference fits or operating temperatures reduce running clearance. Its robust 62 series construction is suited to industrial motors, pumps, conveyors and mechanical power transmission equipment.
The SKF 6215-2RS1/C3 sealed deep groove ball bearing provides dependable shaft support in industrial rotating machinery where load capacity, contamination protection and internal clearance are important selection factors. Its 75mm bore, 130mm outside diameter and 25mm width make it suitable for equipment designed around the 6215 bearing envelope. The single row deep groove raceways carry predominantly radial loads while accommodating axial forces in either direction within the bearing's rated limits. SKF specifies a basic dynamic load rating of 68.9kN and a basic static load rating of 49kN, making these figures useful for evaluating bearing fatigue life and stationary loading. The SKF Explorer performance class and sheet metal cage further identify the bearing's construction.
The 2RS1 rubber contact seals retain factory-applied grease and help prevent dust, dirt and moisture from reaching the rolling elements. Unlike a standard-clearance 6215-2RS1, the C3 suffix indicates greater-than-normal radial internal clearance before mounting. This can help compensate for clearance reductions caused by tight shaft fits and differences in operating temperature, although the required clearance should always be calculated for the installation. SKF publishes a limiting speed of 3,200rpm for this contact-sealed version; continuous operating suitability also depends on load, lubrication, seal friction and temperature. The bearing is supplied greased and has no integrated relubrication provision. When replacing an existing bearing, confirm the C3 designation rather than relying on dimensions alone, and apply installation forces to the ring being fitted.
Typical Applications:
Industrial electric motors with C3 clearance requirements
Centrifugal pumps and rotating process equipment
Conveyor drive shafts and transmission assemblies
Agricultural machinery and industrial processing equipment
Gearboxes and mechanical power transmission systems
