Importance of Proper Bearing Mounting

The two main methods of bearing mounting is through what is referred to as “cold” and “hot” mounting. Cold mounting, otherwise known as mechanical mounting, is mostly used for bearings that range from small to medium. Hot mounting utilizes hydraulics for installation and is more recommended for larger bearing mounting. By utilizing these techniques and using the right fitting tools, correct installation can be done easily, and will help to avoid problems that may arise in the future, extend the life expectancy and performance of the bearings, as well as decrease the amount of downtime for machinery due to repair caused by improperly installed bearings.
 
With cold mounting, using the correct fitting tools can protect the bearing from receiving force damage and ensure a proper amount of force is used during aircraft mounting. With cold mounting, the mistake many people make is to use hammer and pipes, which can lead to damage of the raceways, as well as allows for contamination, such as dirt, to enter the bearing and lead to friction. The bearing’s rolling element can also face damage if the pipe slips during installation.
 
With hot mounting, preheating the bearing can be very beneficial as it allows the inner ring to expand, thus making installation easier. This method also avoids dirt contamination as well as serves as a quick method of mounting. Mistakes that lead to improper hot mounting is through utilizing hot oil baths, which can lead to contamination of the bearing, or by using open flames which can be dangerous in itself. Standard protocol recommends heating through the use of induction before the bearing is installed, allowing for efficiency, safety, and control during the mounting process.
