Better materials and sealing technologies meet the challenges of modern machine tools and coolants. Bigger, faster machine tools obviously put greater demands on spindle bearings. Most spindles use a ...

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 ...

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 ...
