You notice the difference as soon as your machine starts running. Ceramic balls weigh less and move with less friction. The ...

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 ...

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 ...

Precision high-speed machining requires low-friction bearings that provide dynamic stability. Hybrid bearings with ceramic balls run faster and have higher stiffness than comparable all-steel bearings ...

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 ...
