Rotary Table Bearing and cross roller bearings on the function and structure are similar, such as high rigidity, high precision, stable rotation torque, long life and other aspects of performance. In industrial robot joints, nc rotary table, dividing disc, vertical grinding machine, direct drive motor, precision medical equipment and other high-precision processing equipment more and more to abandon the traditional design, the better performance of high precision cross roller bearings.
Rotary Table Bearing domestic popular also called turntable bearing or rotary bearing, is a German company developed a kind of similar to the three row roller rotary bearing structure of the bearing type, relative to the three row roller combination of rotary bearing structure, the advantages of small size, precision grade, high rigidity, high bearing load and resistance to damage, etc. It is mainly used in high-precision CNC turret, nc dial, vertical machining center, vertical grinding machine, military radar and precision medical equipment.
