SKF 6213-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 65x120x23mm

The SKF 6213-2RS1/C3 sealed deep groove ball bearing is engineered for rotating equipment where reliable shaft support and accurately selected internal clearance are essential. Its 65mm bore, 120mm outside diameter and 23mm width provide a substantial bearing arrangement for larger industrial shafts without the radial space required by the heavier 6313 series. The single row deep groove raceways accommodate predominantly radial loads together with axial loads in either direction, subject to operating conditions and rated capacity. SKF lists a basic dynamic load rating of 58.5kN and a basic static load rating of 40.5kN, providing important reference values for bearing-life calculations and load assessments. The SKF Explorer design is intended for demanding industrial applications where durability and consistent running performance are priorities.

The 2RS1 rubber contact seals retain the factory-applied grease and help exclude dust, dirt and moisture, reducing the need for routine relubrication. SKF specifies a limiting speed of 3,600rpm for this sealed configuration, although actual permissible running speed depends on loading, temperature and heat generated by seal friction. The C3 radial internal clearance is a key selection feature: it provides greater clearance than the standard CN version to accommodate applications where interference fits and thermal effects would otherwise reduce operating clearance. C3 does not automatically suit every motor or high-temperature application; the correct clearance must be established from the equipment manufacturer's requirements. During installation, verify the shaft and housing tolerances and apply mounting force to the fitted ring without transmitting it through the rolling elements.

Typical Applications:

Industrial electric motors with specified C3 clearance

Centrifugal pumps and fluid handling machinery

Industrial conveyor drive and pulley assemblies

Agricultural and material handling equipment

Gearboxes and mechanical power transmission systems
