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.

The High Speed Water Tunnel three-component balance [PDF]
, 1955 An experimental program was initiated in the High Speed Water Tunnel to measure force coefficients for hydrofoils under cavitating conditions. This program necessitated either a new force balance or a major modification of the existing one.

Study on the Influence of Mechanical Spindle Axial Movement based on ADAMS Simulation Analysis
Jixie chuandong, 2017 Based on a gear tooth fracture case,which is caused by diesel engine crankshaft axial movement. Aiming at the situation that it’s difficult to simulate this fault by experiment,the displacement and movement type can’ t be control.

Performance of large-bore tapered-roller bearings under combined radial and thrust load at shaft speeds to 15,000 rpm [PDF]
The performance of 120.65-mm bore tapered roller bearings was investigated at shaft speeds up to 15,000 rpm. Temperature distribution and bearing heat generation were determined as a function of shaft speed, radial and thrust loads, lubricant flow rate ...
