Cylindrical Roller Bearings
The cylindrical roller bearing finds extensive application in modern machinery. It operates through rolling contact between its key components, providing crucial support to rotating parts. With widespread standardization, cylindrical roller bearings offer several notable advantages, including small torque required for starting, high rotation accuracy and convenient selection.
-
Single Row Cylindrical Roller BearingsSingle row cylindrical roller bearings are a commonly used type of bearing, featuring a single row of cylindrical rollers arranged between the inner and outer rings.
-
Double Row Cylindrical Roller BearingsDouble row cylindrical roller bearings are renowned for their arrangement of double rows of cylindrical rollers, high load-carrying capacity, and excellent rigidity.
-
Four Row Cylindrical Roller BearingsFour row cylindrical roller bearings feature four rows of cylindrical rollers arranged between the inner and outer rings. Typically comprised of two double row cylindrical roller bearings, these bearings support heavy loads and high-speed rotation by the relative movement of the inner and outer rings.

- Reduced friction and low noise, ensuring durability
- Heavy load-bearing capacity
- Low coefficient of friction
- High limiting speed
- Versatile structural variations available, including N, NU, NJ, NF, NUP, NFP, NH, NN, NNU, NNF, FC, and FCD design
- Cylindrical roller bearings are available in single row, double row, and four-row configurations.
- These bearings excel in withstanding high radial loads and moderate axial loads.
- Featuring cylindrical rolling elements, cylindrical roller bearings are designed with corrective slopes at both ends of the outer ring, effectively reducing contact stress.
- NN and NNU design cylindrical roller bearings exhibit high rigidity, making them well-suited for precision machinery such as milling machines.
