Most linear bearings incorporate ball bearings (usually of metal) to reduce friction between moving parts. Of these designs, most bushings, ball splines, linear guides and slides recirculate balls. As ...

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 ...

A good roller stand offers support for large sheet goods, such as plywood and drywall, and long workpieces that would otherwise be awkward to handle. It also provides smooth movement, allowing for ...

Most all the spinning parts on our vehicles would simply not function well without one simple invention—bearings. You’ll find them in the engine, transmission, transfer case, and axles. Bearings allow ...

Whilst the basic design of a needle roller bearing hasn’t changed a great deal in the last 60 years, continuous developments have resulted in new cage designs that provide five times the service life ...

If the utility of an invention were somehow derived from the genius of its inventor, it would be pardonable that so many sources trace the idea for the ball bearing to a 1497 drawing by Leonardo da ...
