How to obtain Axial Load Capacity from Tapered Roller Bearings Catalog

[AeroGeek]

Hello there,

I'm trying to select a tapered roller bearing (TRB) for my actuator, I know the peak axial force that is going to come. I have some radial load as well.
I want to select the TRB based on the axial load, but all the bearing catalogs or most of them give Dynamic and static Load Ratings.

Do I have to consider the given(from the bearing manufacturers) dynamic load rating as equivalent load and use it?
Thank you in Advance.

All bearing manufacturers usually explain how to select bearing size and give all the needed info.

You got the basic info very well-presented here. But SKF shows a more in-depth presentation of the same info here.

Thank you, it's really well shown here. Yes, some bearing manufacturers have more in-depth, and its confusing sometimes which to consider.

Hi I have gone through many literature now. and yet i'm unable to figure out why the Back to Back Tapered roller Bearing arrangement is better in axial load capacity. How to justify with numbers when compared to face to face configuration

I calculated the loads on points A and B, Keeping the bearings the same in back-to-back (DB) and face-to-face (DF), L2 for back-to-back is 4-5 times that of face-to-face, i.e. 50 mm for DB and 10mm for DF. After the calculations for Equivalent load and bearing life, both have not changed much. there is a slight reduction in Equivalent load and Bearing for the DF. If the difference is so less, then can I not use DF instead of DB ?
But all the textbooks and literature says DB has more axial load capacity and rigidity. I agree with rigidity because of L2, but in my case, since the bearings are very close that I am unable to figure out which is a better configuration.
In my case, the Axial load is higher, and the radial load is minimal.? Any thoughts would be welcome
