Bearings are meant to be part of a small system that allow a larger 
system to function that in turn allow a machine or engine to work 
flawlessly. A bearing is the most vital part of a machine you will never
 see.
A bearing is a team player,a supporting actor in a larger cast in this 
case a bearing flange a flange is not simply housing for the bearing it 
ensures the safety of the two connected pipes and reducing friction as 
any bearing does however this bearing is special due to its housing. 
It’s housing allows it to withstand a high vibration environment also it
 is made to carry heavy loads and high temperatures.
These bearings are ever correcting as the shaft requires.
As for what they are made of different materials as different materials 
have different properties in different environments, they must have 
endurance properties including temperature and weight endurance such as 
aluminum which has all of those properties speed endurance, temperature 
endurance and lifetime.
A flange is the only thing keeping piping systems from falling apart.A 
bearing is equally important a vital part of the moving parts of the 
machinery surrounding us. The bearing is surrounded by it’s housing 
making sure it stays secure from all the surrounding moving parts. The 
housing remains motionless allowing the bearing to move only in the 
desired direction and not move freely.there are different types of this 
bearing as its not one size fits all.
Four bolt which has four mounting holes located around the bearing axis.
What ball bearings are suited for these different mounts simply put a bearing with both high rolling elements and roller bearings which decrease friction.
* Cylindrical roller bearings are able to function carrying high radial load bearing capabilities.
* Spherical roller bearings
* Tapered roller bearings
* Needle roller bearings
* Plain bearings
* Sleeve bearings
