If the geometry is purely a revolved feature, and the loads are axisymmetric, then you should create an axisymmetric model and only mesh the surfaces on a radial slice in the X-Y plane where Y is the axis of revolution.

If you need to apply loads in 3D, then you can still bring in just the radial slice, but use the Pull feature to revolve the 2D mesh around the axis.  Here is the 2D mesh:

Here is the 3D mesh after using the Pull feature.
