What are Cylindrical Roller Bearings?

Cylindrical Roller Bearings are bearings in which cylinders are used as the rolling elements, as opposed to the balls you find in ball bearings.

The cylinders are slightly greater in length than diameter and the rollers have a greater (linear) contact area with the outer ring. This means that they have a greater radial load capacity and are able to distribute loads across a broader surface. They are also suitable for higher speeds than other types of roller bearings.

There are multiple variations of cylindrical roller bearings and they can be made with a cage, or as a full complement part.

There are various cylindrical roller bearing types, including:

  • Full complement cylindrical roller bearings
  • Caged units
  • Sealed cylindrical roller bearings
  • Split cylindrical roller bearings
  • Single-row cylindrical roller bearings
  • Double cylindrical roller bearings

Axial cylindrical roller bearing

Cylindrical roller bearings are manufactured in single and double-row formats. Typically, these are designed with a cage comprising solid inner and outer rings, together with cylindrical rollers.

The outer rings have rigid ribs on both sides, while the inner rings have one or two rigid ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.

Cylinder roller bearings can also be produced without ribs, depending on the application. Such products can be used as free-end bearings. This allows the rings to move axially relative to one another.

Cylindrical roller bearings are suitable when:

  • Bearing arrangements are subjected to high radial loads.
  • Whereby high axial loads in conjunction with radial loads from one or both directions must be supported.
  • Axial displacements of the shaft relative to the housing must be compensated without constraint in the bearing.
  • Bearings should be repairable for easier mounting.

What are Full Complement Cylindrical Roller Bearings?

Full complement cylindrical roller bearings maximise the number of rolling elements in a given envelope. This allows them to offer an extremely high radial load-carrying capacity, as well as high levels of rigidity. This makes them suitable for extremely high speeds, or particularly compact designs.


Cylindrical Bearing Applications

Cylindrical roller bearing uses vary greatly; they can be used across a range of industrials.

The most popular cylindrical roller bearing applications include:

  • Oil and gas
  • Machinery
  • Gearboxes
  • Electric motors
  • Pumps
  • Wind turbines


Our Range of Cylindrical Roller Bearings

Our product range comprises:


Cylindrical type NU bearing







The outer ring has 2 rigid ribs while the inner ring has no ribs. This design allows axial displacements of the shaft relative to the housing in both directions and within certain limits.


Cylindrical type N bearing







The inner ring has 2 rigid ribs while the outer ring has no ribs. Again this design allows for axial displacements as per the NU


Cylindrical type NJ bearing







The outer ring has 2 rigid ribs where the inner ring has 1 rigid rib. In this design axial displacements are possible in one direction only.


Cylindrical type NUP bearing







The outer ring has 2 rigid ribs, while the inner ring has 1 rigid rib and one loose washer on the opposite side to the rib on the inner ring. Generally axial displacements between the shaft and housing are not possible as these type of bearings are generally used as a fixed locating bearing.
