Nonlinear dynamic analysis of bi-directional porous aero-thrust bearing systems
Advances in Mechanical Engineering, 2017 For some years, bi-directional porous aero-thrust bearing systems have been receiving much attention. They are now applied extensively where there is a need for rigidity in high-precision instruments and mechanisms that run at high speed.

Performance tests with a 4.75 inch bore tapered-roller bearings at high speeds [PDF]
The tapered-roller bearings were tested at speeds to 15,000 rpm which results in a cone-rib tangential velocity of 130 m/sec. (25,500 ft/min). Lubrication was applied either by jets or directly to the cone-rib, augmented with jets.
