In the cylindrical roller bearing range, the single row roller bearing withstands high radial loads. The standard ISO ranges (NU, N, NJ, NF, NUP, NH, RNU, HJ) are available with different types of cage, bore diameters, shoulder rings.
There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).
Double row cylindrical roller bearings are available in several designs with a cylindrical or tapered bore. The standard assortment presented in this section includes:
NNU design bearings
NN design bearings
NNUP design bearings
