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.

Spindles designed for machine tool applications, such as milling, grinding and turning, require the bearings to be set in preload to meet speed, stiffness and accuracy requirements. More importantly, ...

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 ...

If bearing wear is not controlled, complete axle deterioration may result from loss of preload which affects the rigidity of the gear mounting. The effect of excessive gear wear debris on hypoid axle ...

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 ...

For the benefit of our readers, what is the principle of Aerostatic bearings, and how do they compare to roller-element or oil hydrostatic bearings? There are two types of aerostatic bearings, inlet ...

Editor's note: An updated version of this information can be found here. Bearings are used to help reduce friction. Metal-upon-metal contact produces large amounts of friction. The friction adds to ...
