Cylindrical Roller Bearings

Cylindrical roller bearings feature line contact between the rollers and raceways. These bearing offer high load-carrying capacity and are primarily designed to carry radial loads. The rolling elements have minimal friction with the ring ribs, making them suitable for high-speed rotation. Depending on whether the rings have ribs or not, they can be classified into single-row cylindrical roller bearings such as NU, NJ, NUP, N, and NF, double-row cylindrical roller bearings such as NNU and NN, and four-row cylindrical roller bearings such as FC, FCD, and FCDP. These bearings have a separable structure with separable inner and outer rings.
