The SKF 6403-2RS1/C3 sealed deep groove ball bearing provides substantial load support where a 17mm shaft must withstand demanding operating conditions. Its 62mm outside diameter and 17mm width distinguish it from the smaller 6303 bearing, which measures 17 x 47 x 14mm. This larger cross-section makes the 6403 series a practical option where the housing can accommodate the additional radial and axial space. Its single row deep groove raceways carry predominantly radial loads together with axial forces in either direction, within the bearing's operating limits. SKF specifies a basic dynamic load rating of 22.9kN and a basic static load rating of 10.8kN. These ratings assist with assessing fatigue life and resistance to permanent deformation under load.
The 2RS1 rubber contact seals provide protection on both sides, retaining factory grease and helping exclude dust, moisture and other contaminants. Unlike the standard-clearance 6403-2RS1, this C3 version has greater-than-normal radial internal clearance. This can help compensate for clearance reduction caused by interference fits or thermal expansion, but its suitability must be checked against the actual operating conditions. SKF specifies a limiting speed of 8,500rpm for this sealed C3 variant. The bearing has a sheet metal cage, bearing-steel construction and an approximate mass of 0.27kg. It is supplied grease-lubricated without a relubrication feature. For replacement, verify the full 6403-2RS1/C3 designation because selecting the CN version changes the initial internal clearance.
Typical Applications:
Industrial electric motors with specified C3 clearance
Heavy-duty compact gearbox shaft supports
Agricultural machinery and mechanical drives
Industrial pumps operating under variable thermal conditions
Power transmission assemblies with interference-fitted shafts
