The SKF 6220-2RS1 sealed deep groove ball bearing provides a substantial bearing arrangement for large industrial shafts subject to demanding radial loads. Its 62 series geometry offers a wider raceway and greater carrying capacity than lighter 60 or thin-section series bearings of the same bore. The single row ball design also accommodates axial loads acting in either direction, provided the application remains within the bearing's operating limits. SKF catalogue specifications give a basic dynamic load rating of 127kN and a basic static load rating of 93kN. These values make the bearing relevant to heavy industrial drive systems, although actual service life must be calculated against load magnitude, duty cycle and lubrication conditions.
The 2RS1 contact seals provide a protective barrier on both sides of the bearing, helping to retain its factory grease and restrict the entry of dirt and moisture. This arrangement is valuable for enclosed machinery where routine relubrication access is limited. The contact-sealed configuration has a published limiting speed of 2,400rpm, making temperature control and seal friction important considerations during continuous operation. Its normal radial internal clearance differs from a C3 version, so the specified shaft fit, housing fit and thermal conditions must be checked before installation. For replacement work, verify the full 6220-2RS1 designation rather than confusing it with the much smaller 62200-2RS1 or a differently sealed 6220 bearing.
Typical Applications:
Large industrial electric motor assemblies
Heavy-duty conveyor drive shafts
Industrial pump and fluid-handling equipment
Large ventilation fans and blower systems
Mechanical power transmission machinery
