To help you understand it in a better way, this blog covers how roller bearings are different from cylindrical roller bearings. At first glance, roller bearings and cylindrical roller bearings may look quite similar. However, there are actually several key differences between these two types of bearings that can impact their performance. In this article, we will explore the key differences between roller bearing and cylindrical roller bearing so that you can choose the right type of bearing for your needs.

What Is Roller Bearing?

Roller bearings are a type of bearing that uses rolling elements to support the loads on the shaft or journal. Roller bearings differ from other types of bearings, such as ball bearings, in several ways. One key difference is that roller bearings can handle both radial and thrust loads, while ball bearings can only handle radial loads.  Additionally, roller bearings typically have a higher load capacity than ball bearings. Another key difference is that roller bearing have a higher friction coefficient than ball bearings, meaning they are not as efficient in terms of energy usage. Finally, roller bearings tend to be more expensive than ball bearings.

How Roller Bearing is different from cylindrical roller bearing?

Roller bearings are one type of bearing that uses rolling elements to support loads. These rolling elements, called rollers, can be cylindrical, needle-shaped, or spherical. Roller bearings can support heavy radial loads and moderate thrust loads in either direction. Cylindrical roller bearings are a subset of roller bearings that have cylindrical-shaped rollers. These rollers are typically wider than they are long and they have a barrel-shaped profile. Cylindrical roller bearings can support heavy radial loads and high thrust loads in one direction.

Based on usage

Roller bearings are classified as either radial or thrust bearings based on their intended usage. Radial roller bearings handle mainly radial loads, while thrust roller bearings handle mainly axial loads. However, both types of roller bearings can accommodate some amount of mixed loading. Cylindrical roller bearings, on the other hand, are only designed to accommodate radial loads.

Based on the surface area

Roller bearings are classified as either spherical or cylindrical. The main difference between these two types of roller bearings is the surface area that comes into contact with the inner and outer rings. Spherical roller bearings have a greater surface area than cylindrical roller bearings. This gives them the ability to handle higher loads. However, this also makes them more expensive to manufacture.

Based on load capacity

Roller bearings are also classified as either single-row or double-row. This designation is based on the number of rows of rollers that come into contact with the inner and outer rings. Single-row roller bearings can handle lower loads than double-row roller bearings. Double-row roller bearings are more expensive to manufacture than single-row roller bearings.

Based on Reuse and Replacement

When it comes to roller bearings, there are two main types: roller bearings and cylindrical roller bearings. Both types of bearings have their own unique benefits and drawbacks that make them suitable for different applications. 

Key Difference Between Roller Bearing and Cylindrical Roller Bearing

Here’s a quick rundown of the key difference between roller bearing and cylindrical roller bearing that will help you understand the role of two different bearings without any doubt: Roller Bearings:
  1. Roller bearings are typically cheaper than cylindrical roller bearings.
  2. Roller bearings can be reused more easily than cylindrical roller bearings.
  3. Roller bearings generally have a shorter lifespan than cylindrical roller bearings.
  4. Roller bearings have greater stability and rigidity.
Cylindrical Roller Bearings:
  1. Cylindrical roller bearings can handle higher loads than roller bearings.
  2. Cylindrical roller bearings are less likely to suffer from misalignment issues than roller bearings.
  3. Cylindrical roller bearings typically have a longer lifespan than roller bearings.

Conclusion

In conclusion, roller bearings and cylindrical roller bearings are two types of bearings that serve different purposes. Roller bearings are designed for use in applications where there is a need for high load capacity and low speed, whereas cylindrical roller bearings are designed for use in high-speed applications.

Solid Lubricant Vs. Oil Lubricant

Needle Roller Bearing
Negligence in lubricating the bearings can be the cause of bearing failure. Therefore, it is crucial to select the suitable bearing lubrication method as per the need and application to protect machinery and improve the service life of the bearing. Read this blog to learn the difference between molded oil and oil lubricant. Lubricants play a crucial role in bearing functioning and preventing it from damage like wear. It also protects against breakdowns when bearings are exposed to high-performance applications. Furthermore, preventive maintenance followed by lubrication intervals can substantially improve the performance and durability of the bearing. Therefore, one should choose a proper lubricant for the appropriate functioning of the machinery..

Why use Lubrication for Bearings?

The prime importance of lubrication is to prevent metal-to-metal contact between sliding and rolling surfaces, causing wear and tear in the longer run. In addition, the lubrication helps avoid damage to bearings ensuring better performance and service life. It also dissipates the heat generated from friction and eliminates the chances of foreign materials interrupting bearing performance due to dust or other elements.

Application of molded oil Lubricants Vs. Oil Lubricant

Different types of lubricants can be used and applied to various bearings. There are two different types of lubricants used in varied scenarios.

Use of molded oil Lubricants in Bearings  

Molded oil lubricants are microporous polymers filled with oil. These are particularly used in scenarios where relubrication is impossible and can offer a better option due to the non-leak characteristics. (The Polymer, Polyolefins are spongy and supply and retract the Lubricating Oil) These types of bearings are primarily used in the food industry as they protect machinery from exposure to contamination due to oil-based lubricants. It works very well in Contaminated ambiances like Material Handling.

Use of Oil Lubricants in Bearings

Oil is one of the easiest methods to apply lubrication to bearings. The two oil-based lubricants used in industry are mineral oils and synthetic oil. Due to the higher temperature in ball bearings, the oil is the perfect lubrication method that can be used to Take away the heat. Therefore, the only crucial thing to consider while using oil lubricants is balancing the viscosity and Additive Base as per the bearing application. 

Difference between Molded oil Lubricant and Oil Lubricant

  1. Factors of Re-lubrication: The oil lubricants are easier to apply but may require oil changing to ensure optimal performance. In comparison, molded oil lubricants are steadier and don’t require lubrication for a longer time.
  2. Suitability: The molded oil lubricants can be used as a permanent or long-term solution for bearing lubrication for specific types of bearings. On the other hand, oil lubrication can be used in such applications where the circulation of bearing lube is required. 
  3. Speed: Oil lubrication is widely recommended for high-speed bearing applications as it can eliminate heat more effectively, preventing bearings from breakdown due to high-temperature operation.
  4. Leaking: In such applications where leaking is a primary concern, an oil-based lubricant cannot work. Molded oil lubricants can easily be used as sealings to ensure proper lubrication due to their solid properties.
Conclusion Lubrication is essential for bearings; the most crucial thing here is choosing the correct lubrication method. Since oil and molded oil lubricant have varied advantages, lubricant selection largely depends on the application and the bearing type.

  • Axial Displacement: The bearings are designed to support axial loads and facilitate movement to and from axial directions within the machinery. The N and NU types of cylindrical roller bearings are perfect use cases for axial displacement, as single-row cylindrical roller bearings offer the scope of axial displacement in some limits relative to the housing.
  • Withstand Incidental Thrust Loads: The thrust load is a load that is applied parallel to the rotation of the axis. The NF, NJ, and NUP series of cylindrical roller bearings are designed in such a way as to withstand incidental thrust loads apart from radial loads.
  • Uses in Heavy Machinery and extreme systems: The cylindrical roller bearings are used in high-speed systems and can be deployed for high-performing systems such as agricultural machinery, wind turbines, mining machines, etc.
