Track rollers with cylindrical rolls - NUTR Series
The rollers of this type of bearing have a very thick outer ring in order to guarantee the mechanical strength to reduce deformations due to loads and to bear high impacts.
The ring is cambered in order to prevent possible concentration of loads on the side bands of the bearing ring, to reduce the contact pressure, so less wear and longer life of the runway.
This type of product is a unique group and, being equipped with a pivot with threaded shank, it is very easy to install.
The full complement cylindrical roller set allows to bear high specific pressures and impacts deriving from the use of these bearings as pressure rollers, cam followers and conveyor belt rollers. They are suitable for bearing loads with axial components.
