Cylindrical roller bearings are equipped with a cage between the rollers, which prevents the roller from tilting or rubbing against other rollers, and efficiently balancing the increase in the rotation torque. This series includes single row cylindrical roller bearings, and double row cylindrical roller bearings.
Single row cylindrical roller bearings are separable, and are capable of bearing only a radial load. This makes them ideal for large electrical machinery, such as a tractor gear box.
Double row cylindrical roller bearings have compact structure, good rigidity and large load capacity, which are ideal for spindle bearings in machine tool spindles.
Cylindrical rollers are available in different types such as NU, NJ, NUP, N, NF (for single row bearings), NNU and NN (for double row bearings, depending on the design with or without side ribs).
All types are available with separable outer and inner rings.
