SKF 3 Medium Series Ball Bearing, 105mm Inside Diameter, 225mm Outside Diameter - 6321/C3
This ball bearing provides radial support for rotating shafts in industrial equipment, designed for installations requiring a cylindrical bore and open-ended access. It suits applications where a single-row deep-groove configuration is needed to manage combined loads and enable smooth, continuous rotation at moderate speeds.
Features and Benefits:
• High dynamic capacity enables Durable load cycling
• Elevated static capacity resists deformation under standstill loads
• Internal clearance increased for thermal shaft expansion
• Sheet-metal cage improves stability at operational speeds
• Cylindrical bore accommodates straightforward shaft fits
• Open-end construction allows easier assembly and inspection
• Elevated static capacity resists deformation under standstill loads
• Internal clearance increased for thermal shaft expansion
• Sheet-metal cage improves stability at operational speeds
• Cylindrical bore accommodates straightforward shaft fits
• Open-end construction allows easier assembly and inspection
Applications
• Suitable for conveyor drives in automated material-handling systems
• Ideal for electric motor rotor support in industrial drives
• Used with gearboxes in mechanical power-transmission assemblies
• Can be used for spindle support in electrical actuation modules
• Suitable for rotating assemblies in electronic testing rigs

What operating speed can be expected during continuous use?
The bearing is rated for continuous operation up to 4000 r/min under appropriate lubrication and alignment conditions, making it suitable for moderate-speed rotating machinery.
How does the internal clearance affect installation in temperature-variable environments?
The increased internal clearance classification accommodates shaft growth from thermal effects, reducing the risk of preload increases during high-temperature operation.
What material considerations affect contamination resistance and life?
The rolling elements are manufactured from bearing steel and run in hardened races, providing surface hardness that helps resist wear, the sheet-metal cage maintains ball spacing while permitting lubricant flow.
How should load capacity figures influence selection for heavy-duty applications?
Use the dynamic capacity of 182 kN to calculate life under expected radial and axial loads and consider the static capacity of 153 kN where the bearing may be subject to heavy static or shock loads.
What mounting features aid integration with driven shafts?
The cylindrical bore design facilitates straightforward press or interference fits on shafts, simplifying alignment procedures during assembly.
