NU 202 ECP

NU type single row cylindrical roller bearings

Single row cylindrical roller bearings are designed for applications subject to heavy radial loads and high speeds. NU type bearings have an outer ring with integral retaining edges on both sides and an inner ring without retaining edges, allowing bi-directional axial displacement. An important feature is the separable design, which facilitates mounting, and the individual parts of the bearing are interchangeable.

  • High radial load carrying capacity
  • Low friction
  • Long service life
  • Can withstand bi-directional axial displacement
  • Separable design
