Super precision double direction angular contact ball bearings are designed to locate spindle shafts axially in both directions. They can accommodate axial forces in both directions and are available in two main designs: BTW, the basic series bearings, which accommodate greater axial loads; BTM, the high-speed series bearings, which accommodate higher speeds.
Very high running accuracy;High axial load carrying capacity in both directions;High axial rigidity;Two main designs to accommodate greater load carrying capacity or rigidity and speed
