Decoding the designation

21314 is the 213 spherical roller series at a 70 mm bore. CC is SKF’s pressed steel window cage, guided on the inner ring. C3 is radial internal clearance greater than normal. Written as 21314-CC/C3, 21314 CC C3 and 21314C3.

What these specs mean in practice

The 213 series runs a shallower roller profile than the 222 and 223 series on a comparable bore, so it takes a smaller misalignment angle and puts more of its capacity into pure radial load. Two rows of rollers on a common spherical outer raceway still let the inner ring and roller set swivel inside the outer ring, absorbing shaft deflection without loading the roller ends, and the bearing carries thrust in both directions. C3 clearance leaves extra room at rest for the interference fit on the shaft and the running temperature difference between shaft and housing to take up.
