Cam rollers
SKF cam rollers (yoke-type track rollers based on ball bearings) are available in two main designs and also as variants of these:
single row cam rollers based on deep groove ball bearings in the 62 series (fig. 1)
double row cam rollers based on double row angular contact ball bearings in the 32 dimension series (fig. 2)

Cam roller features
Accommodate high radial loads
The thick-walled outer ring enables high radial loads, while reducing distortion and bending stresses.
Accommodate tilting moments
Double row cam rollers accommodate higher tilting moments than single row cam rollers.
Long service life
The crowned outer ring running surface is beneficial for applications where outer ring tilting relative to the track may occur or where edge stresses need to be minimized.
Relatively high speed capability
