  • Ball screw basics
    -- eliminating backlash. Preload also defines the contact between balls and races. But what are the differences, and how should one make the choice between the various methods? Balls running between flat surfaces have small contact patches with each other and cannot transmit high loads. Thus ball
  • Throwing it in reverse with rolling-ring bearings
    the bearings a contoured, central ridge running around the entire inner race. Ball bearings have perfectly smooth, flat inner races. When mounted on a shaft, standard ball bearings reduce friction in the hub of rotating assemblies, such as a wheel. Shaft-to-ring contact is across the full surface of its inner
  • Linear-Bearing Design Considerations
    . With a flat race, balls have lower load capacity than rollers and large-diameter balls have to be used to carry the same load. If the mating way is ground with either a Gothic arch or circular groove, the closer conformity to the ball allows the use of smaller balls than with flat ways.
  • Increasing Rolling Contact In Linear Guides
    This shows a double-sided way with two single-sided bearing blocks. Friction-type linear bearings with flat sliding surfaces provide high load capacity and stiffness between bearing surfaces. Unfortunately, they also exhibit the stick/slip phenomena caused by the difference between static
