Cylindrical Roller Bearings | Sabongui Egypt

Roller Bearings are used in situations like conveyer belt rollers they have to hold heavy radial loads.They have a high radial load capacity and are suitable for high speeds. 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).
