3.Cross roller bearing SX series (outer ring split type, inner ring rotation)

Its structure is similar to the RB series. The outer ring is a two-section structure, which is connected by three fixed rings and designed as one inner ring, suitable for the parts requiring high rotation accuracy of the inner ring.
Cross roller bearings are cylindrical rollers arranged vertically through isolation blocks on a 900-shape v-groove rolling surface, so they can bear radial load, axial load and torque load in multiple directions. The size of inner and outer rings is miniaturized, and the extremely thin form is closer to the limit of small size, and has high rigidity, and the accuracy can reach level P5, P4 and P2. Therefore, it is suitable for joint and rotating parts of industrial robots, rotary table of machining center, precision rotary table, medical machine, calculator, military industry, IC manufacturing equipment and other equipment
