Learn to understand common tapered-roller bearing configurations for spindles, and the guidelines for designing a high-speed machine tool spindle with precision-class TRBs. Timken roller 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 ...

Shown are plots of representative bearing types with standard inner and outer race curvatures. Radial play, end play, and contact angle all provide a measure of bearing movement. But, it's not always ...

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 ...
