A Guide to Selecting the Correct Oilless Bearing

With dozens of types of oilless bearings and hundreds of thousands to choose from, selecting the correct bearing for your application can be a daunting task.

Generally speaking, the following factors should be considered in the following order: size restrictions, precision requirements, bearing load, operating speeds, durability, and maintenance issues.

Load Capacity

The bearing you choose must be able to support the load your application requires. Be sure to consider both radial and axial loads, as well as any combined loads your equipment may experience.

Speed Requirements

Bearings have different speed capabilities, so it’s essential to select one that can handle your application’s required speed. Failure to do so can lead to excessive heat generation, premature wear, and equipment failure.

Operating Environment

The environment in which your bearing will operate plays a crucial role in its selection. Factors such as temperature, moisture, dust, and chemical exposure can all affect the performance and lifespan of a bearing.

Lubrication

Proper lubrication is critical for the performance and longevity of a bearing. Consider the type of lubrication required for your bearing, as well as any special maintenance needs that may arise due to the lubrication method.

The Importance of Choosing the Right Bearing

Ensuring Proper Functionality

The right bearing ensures that your equipment functions correctly and efficiently. An improper bearing can cause excessive friction, leading to overheating, wear, and equipment failure. By selecting the appropriate bearing, you can ensure smooth and reliable operation.

Extending Equipment Lifespan

The lifespan of your equipment depends largely on the quality and suitability of its bearings. A well-chosen bearing minimizes wear and tear, prolonging the useful life of your machinery and saving you money in the long run.

Reducing Maintenance Costs

Choosing the right bearing can also help you reduce maintenance costs. When a bearing is correctly matched to its application, it will require less frequent maintenance, and the overall cost of upkeep will be lower.

Size Restrictions – Right Bearing Selection

The space allowed for the oilless bearing is usually rather limited. In many instances, shaft diameter or bearing bore diameter is established based on design requirements. Therefore, a bearing’s type and dimensions must fit established specs.

  • Determine the available space: Begin by assessing the dimensions of the space where the bearing will be installed. This includes the shaft diameter, bearing bore diameter, and any other design constraints that will impact the size and type of the bearing.
  • Precision and tolerances: In applications where tight tolerances and high precision are required, such as in dental drills or precision machinery, choosing a bearing with suitable precision and tolerance levels is essential. This may involve selecting a bearing with a specific ABEC rating or opting for custom-designed bearings to meet the specific requirements.

Precision Requirements

The second big consideration when selecting an oilless bearing is precision.

First, Assess the application: Start by evaluating the demands of your specific application. For example, a CNC machine or precision measuring equipment will require high-precision bearings to ensure accurate and smooth operation. On the other hand, applications like shopping cart wheels can function effectively with lower precision bearings.

Then, Consider Load and speed requirements, Tolerance, and clearance, ABEC ratings, Material and manufacturing quality, and finally Custom solutions to meet the precision requirements of your application.

Bearing Load

The amount of load that oilless bearings must sustain will have a big impact on what type of bearing should be used for a particular application. Moreover, the various loads managed by a bearing can significantly affect on-going performance and for that reason must be carefully assessed during the selection process.

Some bearings must handle radial loads, which act perpendicularly to the axis of rotation. Some bearings must handle an axial load, which acts parallel to the axis of rotation. If the load on a bearing is offset from these axes, it creates a moment load.

The qualities, degree, and direction of acting loads can be highly varied. Generally speaking, the fundamental load ratings indicated in bearing dimension tables show load capacity. Yet, in deciding the correct bearing type, thought should also be given to load type.

Operating Speeds

Every particular bearing has specified speed limits, all established from empirical testing conducted across a wide array of conventional applications. The allowable speed can differ based upon bearing size, type, degree of the load, lubrication, and temperature.

A key factor in a bearing’s high-speed performance is the kind and amount of lubrication that has been applied. Oilless bearing are best for high-speed uses.

Durability

There are a number of factors to consider with respect to durability, including rigidity and temperature tolerance. Under loading, deformation along a bearing’s contact surfaces can occur and deformation can be a serious issue in some applications. From the sub-zero temperatures that an Alaskan oil rig must handle to 100-degree deserts of Saudi Arabia, the range of operating temperatures that a bearing will tolerate should also be a major selection concern.

Maintenance

Some oilless bearing applications call for regular disassembly and reassembly to allow for inspections and maintenance. In these applications, bearings with separable rings are the most suitable.

The importance of thorough lubrication cannot be understated when it comes to prolonging and supporting the performance of any bearing type. Too much lubrication, too little lubrication, contamination, and combined lubricants can all have an effect on bearing performance. It’s also crucial to think about “grease service life,” the quantity of time a bearing can properly perform between lubrications.
