The SKF deep groove ball bearing is a single-row component built to handle radial and axial loads in industrial equipment. Its steel cage supports smooth operation, making it a common choice for electric motors, pumps, fans and transmission systems. MR Industrial Accessories LLC supplies this brand and assists with selection from Miami to customers across the United States and Latin America.
The part number tells you what you are getting. Take 6220 M/C4VK121: the digits give the series and size, M stands for a machined brass cage, C4 sets the internal radial clearance, and VK121 points to a specific lubricant or treatment. Reading these codes correctly is how you avoid ordering the wrong replacement.
You will find these bearings in food processing, petrochemical, metalworking and paper mills, as well as in gearboxes, centrifugal pumps, compressors and industrial fans. They run at moderate to high speeds, so they suit rotating equipment where reliability and low maintenance matter.
Selection depends on radial and axial load, speed and the surrounding conditions. C4 clearance is wider than standard and fits interference fits or thermal gradients. The M brass cage is robust for high speeds. Choose sealing and lubrication based on dust or moisture, and make sure shaft and housing alignment is correct to prevent early failure.
When comparing with other brands, check bore, outer diameter and width, but also internal clearance, cage type and lubricant. A code with suffixes like C4 or VK121 may not have a direct equivalent, so verify operating conditions first. MR can help you find a suitable option.
