This is the third and final report in a series, Selecting, Configuring and Lubricating Tapered Roller Bearings for High-Speed Machine Tool Spindles. The first installment is Selecting Tapered Roller ...

Heat is generated either by shearing of the oil film or by rubbing contact. In hydrostatic and hydrodynamic bearings, heat generation at running speeds is the result of oil shear, and the amount of ...

Graphite-metal bearings can handle harsh environments that toast liquid-lubricated types. Agrease-filled ball bearing on an oven-door latch seizes and keeps the door from latching. It turns out the ...

Bearings define speed, load-carrying capacity, precision, and stiffness, and they contribute to the spindle operating temperature, vibration, and noise during operation. It wasn’t so long ago that a ...

The Large Bearing Testing Machine has been developed and primarily used for commercial testing of large bearings. It is capable of applying 1,600 kips (7,117 kN) vertical load, and lateral ...
