Hollow Rotary Tables

Hollow Rotary Tables are mechanical transmission devices mainly used for positioning and transmission of rotational motion. Their core feature is the presence of a through hollow structure at the center of the rotating platform, hence the name "hollow" rotating platform. 

Here, In this page, we briefly introduce categores of our Hollow rotary tables as follows,you can check other pages for special models or types too:

FAQ: 

1. What are the accuracy levels of hollow rotating platforms usually divided into?

Conventional accuracy (positioning accuracy ± 0.01~± 0.05mm), high accuracy (± 0.001~± 0.01mm), and ultra-high accuracy (below ± 0.001mm) are classified according to transmission type and bearing configuration.

2. What scenarios is the hollow structure of Hollow Rotary Tables mainly used for?

Scenarios that require the installation of cables, air pipes, and optical fibers (such as robot joints and detection equipment); Scenes where workpieces or fixtures need to be avoided (such as multi station assembly); Scenarios that require weight reduction or simplification of structure.

3. What are the types of transmission methods for Hollow Rotary Tables?

Gear transmission (medium precision, high load), harmonic transmission (high precision, small size), worm gear transmission (good self-locking, low-speed stability), DD direct drive transmission (no backlash, ultra-high precision).

4. What is the rated voltage and power range of the hollow rotating platform?

The voltage is adaptable to servo motors (AC220V/380V), and the power depends on the matching motor. The conventional range is 0.1~5.5kW, and the micro version can be as low as 0.05kW, while the heavy-duty version can reach more than 10kW.

5. What is the general protection level of Hollow Rotary Tables?

Regular IP54, dustproof and waterproof; Industrial grade IP65, capable of withstanding dust and low-pressure water spray; Special working conditions (such as food and underwater) can be customized with IP67/IP68.

6. What is the weight range of Hollow Rotary Tables and how to adapt it to the load-bearing capacity of the equipment?

Mini models weigh 1-5kg, regular models weigh 5-50kg, and heavy-duty models weigh 50-200kg. When adapting, it is necessary to ensure that the load-bearing capacity of the equipment installation surface is ≥ 1.5 times the weight of the rotating platform+the load weight to avoid vibration.
