Bearing selection process, introduction

Bearing selection process

When selecting bearings for any purpose, Bearing selection process
ultimately you want to be certain of achieving
the required level of equipment performance
– and at the lowest possible cost. Robustness
also is very important because the conditions
in which your equipment is assembled,
operated and maintained may not be pre- Performance and operating conditions
cisely known and may, in fact, vary over time.
In addition to the bearing rating life, there Bearing type and arrangement
are key factors you must consider when put- Bearing size
ting together the bearing speciications for Lubrication
Bearing selection process • lubricant and supply method Operating temperature and speed
an application, including:

• shaft and housing its
• bearing clearance class
Bearing interfaces
• cage material and guidance
Bearing execution
• dimensional stability
• precision requirements
• mounting method and maintenance

B • bearing sealing Sealing, mounting and dismounting
To help evaluate these key factors, we
recommend following the selection process
shown on the right
The process provides a straightforward
step-by-step approach that shows the general
relationship between each step By clearly
deining and naming the steps in this way, it
should be easier to ind information on a
speciic topic In reality, however, you will ind
interdependencies that require you to loop
back and forth between the steps
