NJG 2309 VH

NJG 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 are not supplied with a cage. NJG-type bearings with integral retaining edges on both sides of the outer ring and a retaining edge on one side of the inner ring allow unidirectional axial displacement. The outer ring with the self-retaining roller set can be separated from the inner ring, which facilitates mounting and makes the bearing components interchangeable.

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