We are in need of designing an Oscillating Shaft Structure for one of our product.
The shaft is loaded at several points & hinged at the centre & can oscillate in the top plane in +/-5 Degree.
So including the shaft weight, 1000kgf axial(downward) force will be acting on the pivot shaft where we are going to use the bearing as in the attached picture below:-

There are two choices:-
1. Use an Angular Contact Bearing for carrying the axial load & another Deep Grove Ball Bearing for facilitating easy tilting. (However we hear some unsuitability of using rolling bearing for oscillating applications).
2. Use Plain Bearings (self lubricating bearings from Schaeffler or GGB)where a thrust washer will carry the axial load & a Cylindrical Bush Gearing will help the shaft to tilt easy.
I am attaching a diagram that resembles the application & advise your views on this design as I am not very familiar with the Oscillating Applications:-
