NCF 2326 ECJB

NCF type single row high load bearing cylindrical roller bearings

JOJI single row high load carrying capacity cylindrical roller bearings have the high load carrying capacity of full complement roller bearings and the high speed capacity of bearings with cages. They are designed for use in industrial gearboxes, wind turbine gearboxes and mining equipment. Their internal design allows the bearings to be axially displaced in one direction. The bearings are of non-separable design.

  • High radial load carrying capacity
  • High speed capability
  • High radial stiffness
  • Long service life
  • Unidirectional axial positioning of the shaft is possible
