Cylindrical Roller Bearing: Why Prefer It? - KG International

Cylindrical roller bearings utilize cylindrical rollers as their rolling element and offer exceptional load-carrying capabilities. These rollers are guided by the ribs present on either the inner or outer ring. As both the rings are typically press-fitted into their respective shaft and housing, they can be separated to facilitate easy assembly. Moreover, in bearings without any inner or outer ring ribs, the rings can move freely in the axial direction. This makes cylindrical roller bearings a suitable choice for applications where there is thermal expansion of the shaft in the axial direction 



NTN offers a broad range of cylindrical roller bearings to cater to your specific requirements, including both inch and metric series bearings. Our NTN and Bower® branded bearings utilize premium-grade steels and undergo specialized heat treatments to enhance their reliability and extend their lifespan. Additionally, we ensure strict control over the heat treatment, dimensions, and surface finish of all components, further elevating the performance of our bearings. 


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. 

Worm gearboxes are a crucial component in numerous industrial applications. If you are in the market for a new gearbox, it is important to understand what a worm gearbox is and how it can benefit you. In this blog post, we will provide an overview of worm gearboxes, their components, how they work, the types available, and their advantages.

We will also discuss some common applications of worm gearboxes and why you should choose KG International as your leading provider.

What Is a Worm Gearbox?

It is also known as a worm gear reducer, a gear system used to transmit power between two shafts transmit that are perpendicular to each other. Worm gearboxes are used in many industrial applications, including conveyor systems, packaging machinery, and construction equipment’s. They are designed to be compact, efficient, and low maintenance, making them an ideal solution for many applications.

Components of a Worm Gearbox

They are made up of two main components: the worm gear and the worm wheel. The worm gear is a type of a gear with a screw-like thread that meshes with the teeth of the worm wheel. The worm wheel is a type of gear that is shaped like a ring with teeth on the inside. The worm gear and worm wheel are made of materials such as steel, bronze, or aluminium, depending on the application.

How Does a Worm Gearbox Work?

The worm gear and worm wheel work together to create a gear ratio, which is the ratio between the number of teeth on the worm wheel and the number of threads on the worm gear. When the worm gear rotates, it turns the worm wheel, which in turn rotates the output shaft. The gear ratio of a worm gearbox is typically higher than that of other types of gearboxes,

which makes them ideal for applications where a high reduction ratio is required.

Types of Worm Gearbox

There are two main types of worm gearboxes:

Single Reduction and Double Reduction.

Single reduction: It has one set of gears, while double reduction worm gearboxes have two sets of gears.

Double reduction: They have a higher gear ratio than single reduction worm gearboxes, making them ideal for applications where a higher reduction ratio is required.

Advantages of Worm Gearbox

Worm gearboxes offer many advantages, including:

1. High gear ratios – They can achieve high gear ratios, making them ideal for applications where a high reduction ratio is required.

2. Compact size – They are typically more compact than other types of gearboxes, making them ideal for applications where space is limited.

3. Smooth operation – It is operated smoothly and quietly, making them ideal for applications where noise is a concern.

4. Low maintenance – It requires less maintenance than other types of gearboxes, making them a cost-effective solution in the long term.

It is an important component in many industrial applications, providing high gear ratios, smooth operation, and low maintenance. It is an ideal solution for applications where a high reduction ratio is required, and where space is limited. They are commonly used in conveyor systems, packaging machinery, and construction equipment’s, making them a versatile and essential component for many industries.

Applications of Worm Gearbox

They are used in many industrial applications, including:

Conveyor systems – They are used to drive conveyor belts and other types of material handling equipment’s.

Packaging machinery – They are used in packaging machinery to control the movement of products on the production line.

Construction equipment – They are used in construction equipment such as cranes and hoists to lift and move the heavy loads.
