Linear-motion bearings deal with the problem of providing low-friction translational (rather than rotational) motion. Sliding-surface bearings are stiffer and deflect less under load than ...

Whether freshly felled or dry, hardwood or softwood, trees are among the largest and heaviest items that move through ...

Linear bearings are distinguished from radial bearings by their sliding rather than rotary motion. Linear bearings are used in machine tool applications such as sliding doors, 3D printers, and ...

Rolamite bearings, originally designed for NASA with an order of magnitude of friction lower than ball bearings, can generate cog-free linear motion. A carriage is propelled along a track under the ...
