Cylindrical Roller Bearing: Why Should You Prefer It?

A cylindrical roller bearing is used as the rolling element, and they have high load capacities. The ribs of the inner or outer ring guide the rollers. It is possible to separate the inner and outer rings for ease of assembly, since both rings are normally press-fit into the housing and shaft, respectively. On bearings with no inner or outer ring ribs, the rings can freely move in the axial direction, making cylindrical roller bearings suitable for applications involving shaft thermal expansion in axial direction.

Insights About Our Cylindrical Roller Bearings


Whether you need an inch series, through-hardened cylindrical roller bearing or a metric series, case-carburized model, NTN has a proper bearing for your needs. We can Provide cylindrical roller bearings under the NTN and Bower® brand names, which use premium steels and special heat treatments to increase life and reliability as needed. Controlling heat treatment, dimensions, and surface finish of the  all components further enhances bearing performance.


NTN’s Austenite Strengthening (AS) process strengthens the rolling elements with a special heat treatment. In order to increase bearing life, NTN chemically alters the surface chemistry of the roller, resulting in a thin layer of retained austenite. An AS Treatment contributes to a 1.5 life multiplier.


This unique micro-pitted surface finish increases bearing life for applications with inadequate lubrication due to the NTN High Lubrication (HL) surface treatment. These micro pots, which are designed to enhance oil film formation in bearing contact areas by changing the surface finishes of components, have the ability to capture and channel oil effectively.


By combining a caged design with a full complement bearing, NTN has developed a bearing that combines high load capability with high rotational speed capabilities. It is possible for NTN to keep the same number of rollers as a full complement design while reducing friction and heat generation by placing a resin rolling element separator between the rollers. With the right shape and guidance method, it is possible to achieve high speeds equivalent to those of caged bearings by optimizing the separators.

Bearings come in a wide variety of types and each has its own advantages. KG International offers a range of cylindrical roller bearings to meet your needs. As a result, choosing the right bearing for your application design is vital.


Cylindrical roller bearings and other roller bearing styles differ primarily in their name – as opposed to ball bearings, cylindrical roller bearings use cylinders as their rolling elements instead of balls. The length of the cylinders is same or a little longer than the length. Cylindrical roller bearings are more radially load bearing than ball bearings. Additionally, these roller bearings can accept relatively higher speeds than other types of roller bearings due to their cylindrical shape.

Cylindrical roller bearings come in a variety of types. Cylindrical rollers with one row are the most popular because they’re easily mounted and dismounted. Certain applications may not be able to support these, however. In addition to their greater capacity, axial loads can also be transmitted by using double-row and multi-row cylindrical roller bearings.

There are a variety of clearance options and lubrication options available for cylindrical roller bearings based on the requirements. The cylindrical roller bearing can be manufactured with a cage or as a full complement bearing.


Cylindrical roller bearings are ideal for a variety of industries due to their high radial load capacities, ability to accommodate higher speeds, and other benefits. Typical markets for these bearings include:

  • Electric motors
  • Material handling equipment
  • Pumps
  • Oil and gas industries
  • Gearboxes
  • Wind turbines
  • Machine tool
  • Steel mills


Cylindrical rollers require the same care and maintenance as all other bearings. Cylindrical roller bearings fail most often due to flaking, pitting, cracking, and chipping.

Fortunately, you can limit the chances of bearing failure. You can prevent bearing damage by taking preventative measures. 

No matter what kind of cylindrical roller bearing you need or what other part you need, it’s important to get the exact bearings you need. Our expert team can help you determine whether there is an available bearing for your application or whether you need a custom-engineered solution. Contact us today to get the parts you need.
