SKF 6012-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 60x95x18mm

The SKF 6012-2RS1/C3 sealed deep groove ball bearing provides rotational support for machinery using a 60mm shaft and a 95mm bearing housing bore. Its 18mm width makes it a space-efficient choice where the larger dimensions of a 6212 bearing cannot be accommodated. The single row deep groove raceways support predominantly radial loads together with axial forces in either direction, subject to the bearing's operating limits. Published SKF specifications give a basic dynamic load rating of 30.7kN and a basic static load rating of 23.2kN. These ratings help engineers assess fatigue life and static loading. The bearing's slim 60 series profile is particularly relevant where installation dimensions are fixed and a larger-section bearing cannot be substituted.

The 2RS1 contact seals are fitted on both sides to retain factory-applied grease and help restrict the ingress of dust, moisture and other contaminants. The C3 radial internal clearance is greater than normal (CN), making this version relevant to applications where interference fits or operating temperatures reduce clearance during service. C3 should not be selected automatically: the correct clearance depends on the shaft fit, housing fit, load and thermal conditions. SKF specifies a limiting speed of 4,300rpm for this sealed configuration, with continuous suitability also influenced by temperature, lubrication and seal friction. The sheet metal cage supports the rolling elements, while the sealed construction reduces routine lubrication requirements. When replacing a bearing, confirm that the original equipment requires C3 clearance rather than the standard 6012-2RS1 version.

Typical Applications:

Industrial electric motors with specified C3 clearance

Centrifugal pumps and circulation equipment

Industrial fans and ventilation drive assemblies

Conveyor drive shafts and power transmission systems

Compact rotating machinery with elevated operating temperatures
