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 machine tools continue to make technical advances, thanks in large part to ongoing improvements and fine-tuning in computer numerical control (CNC) machining. Over the past 60 years or so, CNC ...

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 ...
