Crossed roller bearings provide more linear motion accuracy, rigidity, and weight-bearing capacity than other friction-reducing devices such as ball bearings–plus supporting greater moment loads, radial forces, or tilting loads. One crossed roller bearing replaces multiple ball bearings, saving space and costs.
Linear motion is most accurately controlled by crossed-roller slideways, which allow under 2 microns deflection in smaller sizes. Only the major linear guide manufacturer, NB Corporation, offers the award winning, patented STUDROLLER anti-creep design that eliminates crossed-roller retainer slippage.
