what is Right Angle Hollow Gearboxes?
Right-angle hollow gearboxes are compact and versatile gear mechanisms capable of transmitting torque at 90-degree angles. Their hollow shaft design offers additional installation flexibility, such as allowing cables or pipes to pass through the center. These gearboxes are widely used in automation, robotics, and manufacturing, enabling efficient torque transmission and simplifying overall design in space-constrained applications.
The rise of hollow shaft rotary table with right-angle hollow structures allows the output direction of these tables to be adjusted according to actual needs, while also integrating a symmetrical design with secondary reduction motion.
product Features
-
High transmission accuracy
After assembly of the Angle Series servo hollow rotary platform, the diameter and surface of the rotary table are milled again, using the cross-roller bearing on the platform as the rotation center, to ensure symmetry, end runout, and other dimensional tolerances. Specific accuracy is: end runout ≤ 0.01mm, radial runout ≤ 0.02mm, and repeatability of ≤10 arc seconds, meeting the application requirements of precision machining, automated production, and high-precision testing.
-
High rigidity
The rotary table of the Angle Series servo hollow rotary platform is supported by a complete set of high-precision crossed roller bearings arranged in a 90-degree staggered pattern. The roller bearings have a diameter slightly larger than the guide rollers between the inner and outer rings of the bearings, providing axial force between the inner and outer rings of the crossed roller bearings and the roller bearings. The crossed roller bearings have a dynamic load rating of ≥200kN and a static load rating of ≥500kN, capable of withstanding combined radial and axial loads, making them suitable for heavy-duty tooling rotation.
-
Dust and waterproof
The Angle Series servo hollow rotary table utilizes a skeleton seal to isolate the inside and outside of the rotary table, achieving an IP65 dust and water resistance rating. This level of protection can withstand low-pressure water jets (3mm nozzle, 3 meters distance, flow rate of 10L/min, for 3 minutes), making it suitable for harsh, damp and dusty working environments such as food processing and outdoor equipment.
-
Hollow design for easy wiring
The hollow rotating table's rotating table adopts a hollow design, and the servo connection is located on the side, which facilitates the installation of pipes and cables in the fixture and is particularly suitable for the wiring needs of integrated systems.
What are the common uses of right angle structure hollow shaft hollow rotation table?
Robotics: Suitable for automated systems and robotic arms requiring precise motion, such as collaborative robot end-use rotary joints and AGV steering mechanisms, supporting ±180° high-precision rotation.
Packaging and Conveying Systems: Efficient and space-saving layouts can be created with various packaging and conveying systems. For example, the turntable loading mechanism in automated facial mask/battery packaging lines enables 360° continuous indexing at a rate of up to 60 times per minute.
CNC Machine Tools: Provide high-precision support for production processes, such as in the fourth-axis rotary table of a five-axis machining center, suitable for complex operations such as milling and drilling.
Indexing Applications: Rotary tables are commonly used in indexing scenarios to achieve precise workpiece positioning, meeting multi-station processing or inspection requirements.
How to choose a suitable hollow rotary table?
Selecting the right hollow-core rotary stage requires evaluating several key factors to ensure optimal performance for your specific application. First, consider load capacity and torque requirements, ensuring the stage can handle the weight and forces during operation. Rotational speed and accuracy are also important; for applications that require high precision, look for a stage with low backlash and high repeatability. Make sure the stage has the appropriate hollow shaft diameter to accommodate any cables, pipes, or shafts that need to pass through the center, making it ideal for applications involving integrated systems such as robotics or automated machinery. In addition, verify that mounting options are compatible with your existing setup, whether you need a horizontal or vertical orientation. Consider the environment in which the platform will operate-look for a model with the right level of protection to accommodate conditions such as high humidity, dust, or exposure to chemicals. Controller compatibility is another factor: the platform should integrate seamlessly with your motion control system or PLC. Finally, don't forget to consider after-sales support, ensuring reliable technical assistance and warranty coverage.
If it was not confirmed the model you need, please provide the following working condition to us, our engineer shall make calculation and verify the model.
1) Weight of loading
2) Diameter of turntable
3) Max speed. Or how many seconds to rotate how many degrees?
4) Any drawing or photo of your application?
5) Horizontal, vertical or suspension installation?

FAQ
Q: What's the difference between a right-angle hollow gearbox and a regular hollow turntable?
A: The core differences between the two lie in the direction of power transmission and structural design. A right-angle hollow gearbox uses a 90-degree turning mechanism to achieve vertical torque transmission, making it suitable for applications where space is limited and the transmission direction needs to change (such as robotic arm joints and vertical equipment). Regular hollow turntables typically use coaxial transmission and are more suitable for direct horizontal or vertical rotation (such as turntables).
Q: How can I maintain a right-angle hollow gearbox to extend its service life?
A: Regularly check the lubricant level (it's recommended to add special gear oil every 1000 hours of operation).
Clean the surface from dust to prevent foreign matter from entering the sealing gaps.
Monitor the operating temperature (normal operating temperature should be ≤60°C. If exceeded, shut down the machine to check the load and dissipate heat).
Avoid instantaneous shocks exceeding 150% of the rated torque to prevent gear damage.
Q: Can gearbox parameters be customized for specific operating conditions?
A: Yes. We support customization of gear ratios, hollow shaft diameters, mounting flange dimensions, and protection levels. Please provide specific parameters such as load, speed, and ambient temperature. Our engineers will promptly contact you and provide a suitable solution.
Q: What is the warranty period?
A: We offer a 20-month warranty on right-angle hollow gearboxes.
Q: What is the positioning accuracy of right-angle hollow gearboxes?
A: The positioning accuracy of standard models is ≤15 arc minutes, while high-precision custom models can achieve ≤10 arc minutes, meeting the requirements of applications such as semiconductor inspection and optical equipment.
