Yoke type track rollers are single or double row units mounted on shafts or studs. They comprise thick-walled outer rings with a profiled outside surface and needle roller and cage assemblies or full complement needle roller or cylindrical roller sets.
    

   Yoke type track rollers can support high radial loads as well as axial loads arising from slight misalignment and skewed running; they are suitable for applications such as cam gears, bed ways and conveying equipment.

    
   The bearings are available with and without an inner ring and in both sealed and open versions

 

 
Yoke type track rollers with a crowned outside surface are predominantly used in practice since they are often inclined in relation to the mating track and edge stresses must be avoided.

    
   The radius of curvature of the outside surface is R = 500 mm. In the case of NNTR..-2ZL, the radius is indicated in the dimension table.

    
   The series NATR..-PP, NATV..-PP, NUTR and PWTR..-2RS have an outside surface with the optimised INA profile.

  
    
   the Hertzian pressure is lower edge loading under tilting is lower wear of the mating track is reduced the operating life of the mating track is extended.
