Points of contact between rollers and raceways

Guiding rollers (Version V) The guiding rollers have two contact points with the raceways. This creates a well constrained movement of rollers on the raceway, in both radial and axial direction.

Floating rollers (Version P) The floating rollers engage only the peak of the raceway. They are con strained radially but allowed to float in the axial direction between the two shoulders. The rollers can also rotate a little.

Extra-floating rollers (Version U) The extra-floating rollers engage only the peak of the raceway. They are constrained radially but allowed to float in the axial direction without limi tation. The completely flat surface of the rollers allows an axial travel wider than the floating rollers, and they can also rotate a little. (Note: being free from lateral shoulders, extra-floating rollers could run out of the rail or against the bottom rail when exceeding the nominal floating capacity)
