A rotary table bearing is a specialized type of bearing used in rotary tables, which are commonly found in machining and manufacturing equipment.Rotary tables are used to hold and position workpieces during machining operations, such as milling, drilling, and grinding. The rotary table bearing allows for smooth and precise rotational movement of the table.
The design of a rotary table bearing is similar to that of a turntable bearing or slewing bearing. It typically consists of an inner ring, an outer ring, rolling elements (balls or rollers), and sometimes a gear or toothed track on one of the rings. The rolling elements are positioned between the inner and outer rings, reducing friction and enabling smooth rotation.
Rotary table bearings are designed to handle axial, radial, and moment loads simultaneously. They are capable of supporting heavy workpieces and transferring the forces generated during machining operations. The high precision and rigidity of these bearings ensure accurate positioning and stability during rotational movement.
There are different types of rotary table bearings available, such as single-row ball bearings, double-row ball bearings, crossed roller bearings, or three-row roller bearings. The choice of bearing type depends on the specific requirements of the application, including load capacity, rotational speed, and accuracy.
Rotary table bearings may also feature a built-in gear or toothed track on one of the rings, allowing them to be used in indexing or positioning applications. The gear or track interfaces with a motor or other drive mechanism, enabling controlled and precise angular positioning of the rotary table.
