However, there are several types of bearings to choose from, each having its own purpose with its own advantages and disadvantages.  

Bearings Manufacturing Company is committed to being a world-class provider for modified and manufactured ball and roller bearing products. Because of this, we have worked with all types of roller bearings in many different applications across all industries. 

We thought it would be advantageous to create a series of posts that included the main roller bearings types you may need for your projects. The 5-part series will consist of today's topic&#;Cylindrical Roller Bearings answers to your cylindrical questions, Spherical Roller Bearings, Tapered Roller Bearings, Needle Roller Bearings, and Cross Roller Bearings.

But first, let's discuss:

Most bearings with a rolling element fall into two broad groups&#;ball and roller bearings.

Why choose a cylindrical roller bearing over a radial ball bearing?

Cylindrical roller bearings are similar to radial ball bearings in that they are designed to carry a radial load while minimizing friction. Cylindrical roller and radial ball bearings can also handle a small amount of axial loads depending on the application and internal design of the bearings.

In general, roller bearings offer higher load capacities than ball bearings of the same size. The other significant difference between the two bearings is their contact area. For ball bearings, the contact area is a single point where the roller bearings hit a much larger area.

How to choose the correct bearing for your project or application?

When choosing a bearing, you must consider several essential factors. The first factor to consider is the load that the bearing can support&#;load capacity.

There are two types of bearing loads:

&#; Radial load: perpendicular to the axis, act as right angles to the shaft (bearing's axis of rotation). 
&#; Axial (thrust) load: parallel to the axis of rotation, acts in the same direction as the shaft. It is considered when the load is parallel to the post.

Each type is designed to support the radial or axial load. 

If you require a bearing that needs a high radial load, a cylindrical roller bearing is recommended.

The key takeaway:

Know the amount of bearing load your application requires when deciding the best bearing for the job. Typically smaller/lighter loads work best with ball bearings, and heavier load applications work best with roller bearings. 

Onto cylindrical roller bearings and why you might need them . . .

What are cylindrical roller bearings, and why choose them?

The cylindrical roller bearings have a high radial load capacity and are suitable for high speeds. They are in linear contact with the raceways. They are designed to be reliable and a good fit for the environment.

The bearing is highly versatile and can be used for many applications. There are several different types of cylindrical roller bearings on the market.

They vary according to the number of rows of rollers (usually one, two, or four) and if there's a cage or not. No cage allows for the bearing to have more rows, which helps support even heavier radial loads. [source]

These types of bearings are commonly used in rotary applications. 

Cylindrical roller bearings can support significant radial loads (even very significant ones).

Advantages: Long bearing life, support significant radial loads, robust

Disadvantages: Cannot tolerate high axial loads.

Cylindrical roller bearings can take some axial load in one direction when the inner or outer rings have two ribs.

Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.

Summary: What are the significant benefits of cylindrical roller bearings?

  • Greater radial load capacity compared to ball bearings
  • The roller design accepts faster speeds than other types of roller bearings
  • Resist damage from fatigue
  • Have straight outside and inside diameters (can also be tapered)
  • Flush inside the housing
  • Easy to install, which reduces potential installation damage
  • Slim, saves space and weight
  • Comes in several sizes and materials

Top 10 Advantages of Using Cylinder Roller Bearings in ...

Industrial machinery requires precision, reliability, and durability. All these features come with a careful selection of components that have to work in the challenging environments found in industrial settings. 

The cylinder roller bearing is one such important component. This blog covers the top 10 advantages that cylindrical roller bearings have in industrial applications, making them the first choice of any engineer or manufacturer.

High Load-Bearing Capacity

The main reason cylindrical roller bearings remain the most preferred is their high load-bearing capacity. Heavy radial loads are applied to the bearings because of the line contact developed between the rollers and raceways. 

Contrary to ball bearings that create point contact, cylindrical roller bearings spread the load over an expansive area, reducing pressure at one point and increasing their ability to hold the load. 

This makes them particularly useful in high radial load applications, such as heavy machinery, electric motors, and automotive transmissions. Industries like mining and construction, which put high loads on the machinery, benefit immensely from this feature.

Improved Reliability and Durability

The cylinder roller bearing is one of the most reliable and durable bearing types currently available. This design minimizes stress concentrations within the bearing and distributes loads more uniformly over the bearing surfaces. 

This leads to a longer operational life and lower maintenance costs. Materials used in cylindrical roller bearings, such as good-quality steel and advanced lubricants, extend their life. 

This reliability is very important to industries like manufacturing and mining, where continuous operations are essential. This allows companies to minimize the chances of downtime, ensuring continuous production for increased profitability.

High-Speed Performance

Besides high loads, cylindrical roller bearings are suitable for high speeds. This becomes possible because of their precision design and assembly. 

These bearings retain their stability and performance even at high speeds, making them very suitable for use in applications such as turbines, jet engines, and other high-speed machinery. 

This means reliable operation at high speeds without sacrificing too much load-carrying capacity&#;so that the machines can work in diverse conditions without compromising efficiency.

Versatility in Applications

Cylindrical roller bearings are versatile and find applications in many different industries. Their design accommodates different configurations, such as single-row, double-row, and multi-row bearings, to suit the requirements of certain applications. 

Single-row bearings may only accommodate average radial loads; however, double-row and multi-row cylindrical bearings have higher loads applied and have higher rigidity. 

From gearboxes and wind turbines to conveyor systems, cylindrical roller bearings have solutions that will suit varied industrial needs. The versatility of these bearings makes them more widely used, especially by engineers wanting to attain optimum machinery performance in varied industries.

High Radial Play

Another major advantage is the increased radial clearance of cylinder roller bearings. This design allows for a much greater thermal expansion and contraction in applications where temperatures are known to vary. 

One of the common causes of machinery failure is bearing seizure and subsequent damage resulting from thermal expansion. This ability of bearings to retain optimum performance during thermal flux helps in continuous operation without unnecessary hiccups. 

Industries that operate at extreme temperatures, like the production of steel, where the machinery runs at high temperatures, benefit from the increased radial clearance provided by cylindrical roller bearings.

Contamination Resistance

Bearings operating in harsh environments should be able to resist contamination due to dust, dirt, and other external elements. This is attainable in a cylindrical roller bearing by adding seals and shields to stop the entrance of contamination into its inner parts. 

This adds to the life of the bearing and improves its performance under harsh conditions. In sectors like agriculture and mining that involve exposure to a lot of dirt and other particles, this feature of cylinder roller bearings goes a long way in ensuring efficient production. 

This feature not only lowers the occurrence of bearing failure but also increases the time before servicing a given piece of machinery.

Easy Mounting and Maintenance

Cylindrical roller bearings are designed for easy mounting and maintenance. Being separable, mounting and dismounting can be done separately, significantly simplifying the installation process&#;this can be very beneficial if there are frequent replacements of bearings required in an application. 

Besides, their durability decreases the frequency of maintenance requirements, saving industrial operators time and resources. Cylindrical roller bearings are much easier to install and maintain in industries like automotive manufacturing, therefore allowing less production loss during downtime.

High Axial Load Capacity

Though designed as radial load-carrying bearings, these bearings have a rather high capacity for axial loads. This gives the bearing a chance to be used where the forces are combined, both radially and axially. 

This versatility benefits industries such as automotive and aerospace, which rely on the ability to provide reliable performance under different load conditions. For example, in gearboxes, where both types of loads are common, cylindrical roller bearings provide the support necessary for their smooth and efficient running. 

So, this versatility will simplify the design and reduce the need to have multiple types of bearings in a single application.

Reduced Friction and Heat Generation

The design of a cylinder roller bearing minimizes friction and releases less heat while running. The rollers are in line contact with the raceways, and this allows reduced friction as compared to other bearing types. 

Reduced friction not only increases efficiency but also minimizes the risk of overheating, thus increasing durability. 

In high-speed applications, like turbines and electric motors, reduced friction and the generation of heat are important so that performance is maintained and damage is prevented. Cylindrical roller bearings excel in these environments to ensure reliable and efficient operation.

Cost-Effectiveness

Cylindrical roller bearings offer cost-effectiveness in the long term. Their durability, lower maintenance requirements, and improved performance all help lower the total cost of ownership. 

Although the up-front cost of quality cylindrical roller bearings may be higher, the savings made from reduced maintenance, downtime, and replacement costs more than justify the expense. 

Industries can make remarkable savings by investing in quality cylindrical roller bearings that give trouble-free performance over extended periods. This cost-effectiveness is very important for industries with tight budgets and high operational demands.

Conclusion

The several advantages connected with the application of cylinder roller bearings in industries make them an attractive solution. High carrying ability, high reliability, versatility, and cost-effectiveness&#;each provides a solid solution for many different industrial applications.
