SKF 6220-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 100x180x34mm

The SKF 6220-2RS1/C3 sealed deep groove ball bearing is designed to support substantial rotating loads in machinery using a 100mm shaft. Its 180mm outside diameter and 34mm width provide a robust single row arrangement capable of carrying radial loads together with axial forces in either direction, within the bearing's rated capacity. SKF specifications give a basic dynamic load rating of 127kN and a basic static load rating of 93kN, supporting bearing-life calculations and load assessments for industrial equipment. The SKF Explorer performance class and pressed sheet steel cage complement its conventional deep groove construction, while the cylindrical bore enables installation onto appropriately specified shaft seats.

The defining feature of this version is its C3 radial internal clearance, which is greater than normal (CN) clearance. This additional initial clearance can help compensate for reductions caused by tight shaft fits or temperature differences between the inner and outer rings, but it does not mean the bearing is universally preferable to the standard 6220-2RS1. The 2RS1 rubber contact seals protect both sides, retaining factory grease and limiting the entry of dust and moisture where routine relubrication is difficult. SKF lists a limiting speed of 2,400rpm for this contact-sealed configuration. Actual operating suitability depends on lubrication, loading, temperature and seal friction. Confirm both the C3 suffix and the 100 x 180 x 34mm dimensions before replacement.

Typical Applications:

Large industrial electric motors with specified C3 clearance

Centrifugal pumps and industrial process equipment

Heavy-duty conveyor and power transmission drives

Industrial gearboxes and rotating shaft assemblies

Agricultural and materials-handling machinery
