1.	Choose a hanger frame suitable for your application. All 300 Series frames are symetrical, therefore shaft rotation does not need to be specified when ordering.
2.	Choose a bearing cartridge - keep in mind that the 300 series bearing cartridges will only fit in the 300 Series Hanger Frames. Solid bearing cartridges of the same design are less expensive than the split cartridges.
3.	Choose a grade - if you do not know the applicable grade, a grade can be determined based on the maximum temperature and other operating conditions of the application.
4.	Specify the bore size or shaft size required for the application.
5.	A 300-EZ Clip Spring is necessary for each assembly to hold the bearing cartridge in place. The EZ Spring provides easy one hand operation for bearing access.
