Update: I managed to contact one of the application engineers from FAG. I'm working through the issues with them.
The diagram is misleading - it's a direct drive system, no gears and whatnot.
I almost managed to find 35mm Timken tapered roller bearing housed units, but too bad, they don't...
By the way, good news. I managed to ring up the application engineers from one of the bearing companies. Got some help from them.
@drawoh "optimised for radial force" - That's a big problem. This being a model wind turbine the axial force is way higher than the radial force. I may not even...
Also, I managed to get in touch with an application engineer from one of the manufacturer. He says that it is recommended to use matched pair tapered roller bearings ("X" configuration) as the fixed bearing, but they don't normally selling housings that can accommodate taper roller bearings or...
@Tmoose - The image isn't representative. I don't have CAD drawings yet because I haven't firmed up the bearing choice. Hence the picture was taken from the SKF website and then changed a bit.
The significant axial load is about 14kN. Operating rpm fluctuates since its a wind turbine, but max...
@AidanMc - Size, cost and lead times are the main issues.
I considered using thrust bearings, but due to small shaft size (25mm metric dia) thrust bearings e.g. thrust spherical roller, thrust taper roller etc are not manufactured in this size; or require a 3-4 months of lead time for product...
I'm designing a small wind turbine drivetrain that is handling significant axial load in 1 direction (Fa >> Fr) and a very small radial load on both bearings.
1. Locating / non locating bearing arrangement. Is it possible to use a spherical roller bearing for the locating bearing and a radial...
