Here are 7 Critical Factors to be aware of during Selection of Bearings:

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.
• Axial Loads: These forces are parallel to the rotating shaft.

Combined Loads: These loads involve a combination of both radial and axial forces or can be interchangeable between the two.

 

2) The Transmissions Speed

• Bearings must be chosen based on their ability to withstand varied speeds and temperatures.
• Precision bearings are necessary for high-speed applications to prevent issues like vibrations and increased wear.
• Ball bearings are suitable for higher rotational speeds.

Roller bearings are more effective for slower transmissions and can handle heavier loads.

 

3) The Component Temperature

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

Consider operational temperature: Fluctuating and extreme temperatures can impact bearing performance.

 

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.
• Each lubricant type has unique properties and maintenance requirements.

Choose the lubricant based on the specific needs and requirements of your machine equipment.

 

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.

Lower-cost bearings may require more preventive and predictive maintenance, leading to higher long-term costs.

 

7) The Wider Environment

• Consider the operating environment when selecting bearings for your machine application.
• Harsh environments require special bearing materials, lubricants, and shields.

Choose bearings that can withstand the specific conditions of the operating environment to ensure optimal performance and longevity.
