NCF 3009 CV

NCF type single row full complement cylindrical roller bearings

Single row full complement cylindrical roller bearings are designed for applications with extremely heavy radial loads and medium speeds. The bearings can be fitted with more rollers as they do not have a cage. The NCF type bearings have an integral retaining edge on both sides of the inner ring and a retaining edge on one side of the outer ring, allowing unidirectional axial displacement. A retaining ring on the outer ring holds the bearing components together. The retaining ring cannot be subjected to axial loads during operation.

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