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 ...

At light loads an externally pressurized sleeve bearing tends to be stiffest, followed by rolling-element bearings and self-acting sleeve bearings. As loads increase, the rolling-element bearing ...

Even if a CNC machining center is equipped with spindle bearings that are optimized for a duty cycle at the time of purchase, there is no guarantee the bearings will be optimized for future duty ...

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 ...

If you’ve ever played air hockey, you know how the tiny jets of air shooting up from the pinholes in the playing surface reduce friction with the puck. But what if you turned that upside down? What if ...

Schaeffler has patented a pivot cradle bearing for axial piston machines, featuring a bent cage segment that guides rolling bodies. The design includes a synchronization device with a pivoting lever ...
