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 ...

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 ...

They lie at the heart of every fidget spinner and in every motor that runs our lives, from the steppers in a 3D printer to the hundreds in every car engine. They can be as simple as a lubricated ...
