Modern CNC machine tools work under increasingly diverse cutting conditions. They must handle workpieces of various sizes and materials, and produce good surface finishes while operating at ever ...

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 ...

The challenge that machine tool builders face when designing spindles for milling machines and lathes is selecting bearings with the optimal balance of speed, load-carrying capacity, stiffness, and ...

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 ...

Tapered roller bearings are designed to handle both radial and axial loads. They have a tapered inner raceway (called the cone), a tapered outer raceway (called the cup), and conically shaped tapered ...
