  We present SAURON integral-field observations of a sample of 12 mid to
high-inclination disk galaxies, to unveil hidden bars on the basis of their
kinematics, i.e., the correlation between velocity and h3 profiles, and to
establish their degree of cylindrical rotation. For the latter, we introduce a
method to quantify cylindrical rotation that is robust against inner disk
components. We confirm high-levels of cylindrical rotation in boxy/peanut
bulges, but also observe this feature in a few galaxies with rounder bulges. We
suggest that these are also barred galaxies with end-on orientations.
Re-analysing published data for our own Galaxy using this new method, we
determine that the Milky Way bulge is cylindrically rotating at the same level
as the strongest barred galaxy in our sample. Finally, we use self-consistent
three-dimensional N-body simulations of bar-unstable disks to study the
dependence of cylindrical rotation on the bar's orientation and host galaxy
inclination.
