Why Lubrication is Important for Bearings and Other Components

The key to reducing friction in transmission is precision, and bearing lubrication is the solution to ensure that the rolling component functions smoothly. There are numerous causes of bearing failure, such as incorrect mounting or overloading, and lubrication can also be a factor when the incorrect type is used, it is applied improperly, or the right preventative maintenance is not provided.

Why Lubrication in Bearings is Important

Apart from ensuring frictionless power transmission, lubrication also provides a protective barrier between the different components of the bearing, such as the rolling element, outer ring, inner ring, and shield, where necessary. This barrier offers various advantages that can increase the lifespan of the bearing, protect other machine components, and improve the overall production process.

Role of Lubrication in Bearings

  • It prevents oxidization
  • It minimizes corrosion
  • It acts as a contaminant barrier
  • It reduces component friction
  • It decreases usage wear
  • It stabilizes the bearing structure

There are 3 Types of bearing lubricants

1. Grease Lubricant

Grease Lubrication

Grease lubricant is composed of oil base and thickener, which provides varying viscosity from fluid to semi-solid state. It offers versatility in applications for bearings and requires less frequent maintenance. However, due to its partial-solid composition, it may not be suitable for high-load speeds or improper mounting. Nonetheless, grease lubricant provides added protection against corrosion and oxidation.

2. Oil Lubricant

Oil Lubrication

Compared to grease lubricants, synthetic or petroleum-based oils are capable of withstanding high load speeds and capacities, making them a suitable choice for mechanical operations that involve high production, and can prevent costly downtime. However, since oil is a highly fluid liquid that can evaporate when the bearing is not shielded, it needs regular maintenance, including various application methods such as jets and oil baths.

 3. Solid Film Lubricant (Dry Lubricant)

3. Solid Film Lubricant (Dry Lubricant)

Solid Film Lubricant (Dry Lubricant)

Solid film lubricants, such as graphite, boron nitride, molybdenum disulphide, or tungsten disulphide, can be applied onto bearings through burnishing or sputtering to create a solid film in the raceways and balls. Nonetheless, these lubricants are usually considered as a final option for extreme conditions such as vacuum-sealed or radioactive environments.

What things should we consider while selecting a Lubricant:

When choosing a lubricant for your mechanical operations and power transmission components, several factors should be taken into account.

The first is the operating temperature of the equipment, as high speeds and loads generate significant heat that the lubricant must be able to tolerate. If the bearing is not shielded, oil lubricant may evaporate, making grease a better choice if the external conditions and contaminants allow it.

The second factor to consider is the bearing speed and the type of lubrication needed to maintain the appropriate level of friction under those conditions. Grease is not suitable for high speeds, while both petroleum-based and synthetic oils provide the required protection for your bearings sourced from the bearing supplier of Singapore.

The third factor is the harshness of the operating conditions. In environments with high contamination, radioactivity, or vacuum, it’s essential to avoid downtime by selecting a lubricant that can withstand these conditions. In such cases, it may be necessary to apply a dry lubricant in the form of a solid film on the bearing components.

It’s also crucial to consider the viscosity of the lubricant at operational speeds and temperatures. Oils, greases, and dry lubricants can polymerize in transmission, resulting in uneven, tacky layers that act as “speed bumps,” reducing smooth movement and causing unnecessary downtime. Therefore, it’s vital to use lubricants that can withstand temperatures up to 148°C (300°F) when necessary.

3 Best Practices for Lubrication Application

Bearing lubrication is a consistent consideration when looking to improve mechanical operations and reduce downtime. That said, there are three best practices from prior installation to post-management for your bearing, no matter the industry or application.

1. Select the Correct Lubricant

The first essential practice is to carefully choose the appropriate precision component that can offer reliable and efficient frictionless power transmission for your device. This involves considering factors such as the lubrication type, the operating environment, the application, and the bearing type.

2. Apply the Lubricant Correctly

Once you have obtained the appropriate lubricant, it’s crucial to understand the application process and whether your chosen lubricant is suitable for your application requirements. Since some lubricants may require precision tools, you may need the assistance of full-service professionals like the SantEnt. In addition to supplying high-quality bearings, we also offer professional installation services.

3. Maintain the Lubricant Properly

Lastly, during production, your bearing may experience lubricant loss or contamination. Loss can happen due to bearing misalignment or oil evaporation, while contamination occurs when the lubricant comes into contact with surrounding environmental elements like dust or debris. With a well-planned preventive maintenance schedule, your lubrication can provide long-lasting protection for your bearing.

7 deciding factors you should be aware of when selecting the correct bearing:

Tips for selecting the appropriate bearings for your machine's needs

1. The Load Type

Before acquiring a bearing, it is important to understand three types of loads:

  • Radial Loads: These forces act perpendicular to the rotating shaft.
  • Combined Loads: These loads involve a combination of both radial and axial forces or can be interchangeable between the two.
  • Axial Loads: These forces are parallel to the rotating shaft.

 

2. The Transmissions Speed

  • Bearings must be chosen based on their ability to withstand varied speeds and temperatures
  • Roller bearings are more effective for slower transmissions and can handle heavier loads..
  • Precision bearings are necessary for high-speed applications to prevent issues like vibrations and increased wear.
  • Ball bearings are suitable for higher rotational speeds.

 

3. The Component Temperature

  • Lubricant compatibility: Ensure the lubricant used in the bearing is suitable for high-temperature applications and does not evaporate quickly.
  • Consider operational temperature: Fluctuating and extreme temperatures can impact bearing performance.
  • Material selection: Choose bearings that can withstand high-temperature stress without deformation or failure.

 

4. The Lubricant Requirement

  • Lubrication is essential for smooth and efficient power transmission in bearings.
  • Three types of lubricants to consider: grease, petroleum-based oil, and synthetic oil.
  • Choose the lubricant based on the specific needs and requirements of your machine equipment.
  • Each lubricant type has unique properties and maintenance requirements.

 

5. The Bearing Sealant

  • Bearing sealants reduce lubricant contamination and evaporation.
  • Two primary types of bearing sealants: integrated shields and rubber seals.
  • Integrated shields are made of the same materials as the bearing and provide protection.
  • Rubber seals are suitable when high temperatures and speeds are not a concern.

 

6. The Maintenance Program

  • Maintenance is essential for uninterrupted operations.
  • Three types of maintenance: preventive, predictive, and reactive.
  • Bearings using oil-based lubricants often need more frequent maintenance.

Single Row vs Double Row Ball Bearings

A ball bearing is a type of rolling-element bearing that relies on small balls to maintain separation between the inner and outer races. Its main purpose is to reduce rotational friction while providing support for radial and axial stresses. Ball bearings have been in use for many years and find applications in a wide range of devices, from hard drives to skateboards, where they are designed to handle both thrust and radial loads. They are also commonly employed in situations with lower pressures.

The load is transferred from the outer race to the inner race through the balls. The spherical shape of the balls allows for smooth rotation, as they make only minimal contact with the inner and outer races. However, if a ball bearing is not used correctly, it can become a hindrance. Overworking the bearing can lead to deformation of the balls and damage to the bearing due to the limited contact area supporting the load.

Ball bearings are typically manufactured from materials such as chrome steel or stainless steel. In certain consumer applications, glass or plastic balls are also used. They are available in various sizes, ranging from miniature bearings for hand tools to larger bearings for industrial machinery. The load capacity and reliability of ball bearings are key factors to consider when selecting them for specific applications.

Two Types of Single Row Ball Bearings

Deep Groove Ball Bearings

Advantages of Single Row Deep Groove Ball Bearings:

  • High-speed capability
  • Low noise and vibration
  • Easy installation and maintenance
  • Cost-effective
  • Energy efficiency
  • Space-saving design

Types of Double Row Ball Bearings

Angular Contact Ball Bearings

Advantages of a Double Row Angular Contact Ball Bearing:

  • Increased load-carrying capacity
  • Enhanced stiffness and rigidity
  • Improved axial and radial rigidity
  • High-speed capability
  • Versatility in mounting arrangements
  • Space-saving design

Deep Groove Ball Bearings

Advantages of Double Row Deep Groove Ball Bearings:

  • Increased load-carrying capacity
  • Enhanced radial rigidity
  • Space-saving design
  • Versatility in load distribution
  • High-speed capability
  • Low noise and vibration

Difference Between Single Row and Double Row Ball Bearings

Single Row Ball Bearing are the most common type of ball bearing. This bearing has one row of rolling parts, with a simplistic construction. They are non-separable, appropriate for high speeds, and durable in operation. They can handle both radial and axial loads.

Double Row Ball Bearing are more robust than single row and can handle higher loads. This type of bearing can take radial loads and axial loads in both directions. It can keep the shaft and housing axial movement within the bearing’s axial clearance. However, they are also more complex in design and require more precise manufacturing tolerances.

Conclusion

Single Row and Double Row Ball Bearings find extensive usage across diverse applications. Single row bearings are typically employed in light-duty scenarios, whereas double row bearings are better suited for heavy-duty applications. Ball bearings play a crucial role as components in various machinery and equipment.

To ensure the proper functioning of bearings, it is essential for them to endure a minimum load, particularly under conditions involving high speeds, strong accelerations, or rapid changes in load direction. The inertial force of the ball and cage, as well as friction in the lubricant, can have a negative impact on the rolling of the bearing, potentially leading to sliding motion between the ball and the raceway, which may cause damage to the bearing.
