Mechanical speed bearing types of [bearing speed limit speed limit value with benchmark, says its numerical contained in bearing size table] bearing limit speed in bearing types are also not only take to size, keep frame type bearings, precision grade, load conditions such as lubricating way and, therefore, must consider when the choice these factors. The following bearing is mostly for high-speed rotating: deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings

Can satisfy the mechanical axis of bearing types required rigid [bearing load, rolling body and groove contact part will produce elastic deformation. "high rigid" refers to the lesser of the elastic deformation deformation spindle and car] was the last stage, in areas such as slowing device shaft rigidity and improve, still must improve bearing rigidity. Roller bearing load raw deformation ratio ball bearings small. Applied for bearing preloaded (negative clearance) can improve rigidity. This method is applicable to Angle contact ball bearing and tapered roller bearings.
