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 ...

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 ...

This is the third and final report in a series, Selecting, Configuring and Lubricating Tapered Roller Bearings for High-Speed Machine Tool Spindles. The first installment is Selecting Tapered Roller ...

Extreme loads, abrasive conditions, and misalignment risks make mining a punishing environment for bearings. NTN’s ...

A new tapered bearing assembly, developed specifically for roller-cone rock bits, significantly increased bit life for a Middle Eastern operator. This technology can help oil and gas customers avert ...

When a tapered bearing is subject to a load, a force develops between the roller and the cone back-face rib because the load tries to squeeze the rollers out of the bearing. Most of the load is ...
