Hollow Rotary Platforms/Rotary Motion/

  • Product Detail
  • Inquiry

Hollow shaft rotary tables feature a central hollow opening or bore that runs through the entire diameter of the table. Hollow shaft rotary indexers design allows for the passage of cables, pipes, or other components through the center of the table.

Rotation: The table top is mounted on a rotary mechanism that allows it to rotate 360 degrees around the central axis. This rotational capability enables precise positioning and orientation of workpieces during manufacturing, assembly, or inspection tasks.

Load Capacity: hollow shaft rotary platforms are designed to support heavy loads, with capacities ranging from a few hundred pounds up to several tons, depending on the model and size.

Applications: These tables are commonly used in industries such as automotive, aerospace, electronics, and general manufacturing. They facilitate processes like welding, drilling, milling, assembly, and testing of components that require precise positioning and rotation.

Maintenance: Regular maintenance, including lubrication, cleaning, and inspection of the rotary mechanism and bearings, is essential to ensure the long-term reliability and performance of hollow shaft rotary tables.

Hollow shaft rotary indexers are a versatile and valuable tool in various industrial settings, enabling efficient and precise positioning and manipulation of workpieces during manufacturing and assembly processes.
