Selecting a motor for a specific application can be a challenging task. Many factors must be considered, including the application’s required voltage, maximum current and diameter, speed, efficiency, ...

Torque demand is one of the first factors to consider, encompassing nominal torque, acceleration torque, and emergency torque.

Conrad or deep-groove bearings are the most widely used ball bearings. In addition to radial loads, they carry substantial thrust loads at high speeds, in either direction. They require careful ...

Meeting increasing worldwide demand for wind energy depends on reliable turbine performance, and performance can significantly benefit from optimized main shaft and gearbox bearing selection. Wind ...

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 ...

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 ...
