Hollow Rotary Table Gears
Large-diameter drive gears, gear rings and selected pinion components used within precision rotary positioning and indexing assemblies.
Explore Rotary Table Gears →Planetary Gearbox Gears for Precision Reduction
A planetary gearbox uses a compact gear train to transmit torque through a central sun gear, surrounding planet gears, an internal ring gear and a planet carrier. The arrangement allows multiple gear meshes to share load within a relatively compact housing.
Each planetary gearbox gear must be manufactured in accordance with the intended gear geometry, gear ratio, shaft interface and bearing arrangement. Tooth profile, material selection, heat treatment and dimensional accuracy influence the performance of the complete unit.
Our component supply can be evaluated for sun gears, planet gears, internal ring gears, gear-integrated shafts and related precision-machined parts. We also supply finished inline and right-angle planetary gearbox assemblies for customers who require a complete reducer.
Internal Ring Gears and Precision Gear Tooth Machining
Internal ring gears have teeth located along the inside diameter of a gear ring. In planetary gearbox assemblies, these internal teeth engage with the planet gears and contribute to the designed speed reduction.
Manufacturing a compatible internal ring gear requires more than matching its overall diameter. Tooth count, module, pressure angle, tooth profile, face width, concentricity and mounting dimensions must conform to the mating gear set and housing design.
We can review customer drawings for internal gear machining, including selected ring gear components for planetary reducers and other industrial machinery. Existing parts may also be evaluated using samples where sufficient design information is available.
Hollow Rotary Table Drive Gears and Gear Rings
Hollow rotary tables combine a central through-hole, rotating output structure, bearing support and a mechanical drive arrangement. Depending on the model, the transmission may use suitable gear rings, pinions or a different geared reduction mechanism.
Precision-machined external ring gears can form part of the rotary drive system. Gear teeth, mounting hole patterns, bore dimensions and alignment with the supported rotating structure are important for correct assembly and engagement.
Our custom component service can evaluate individual drive gears and related machined parts against supplied drawings. For machine builders who need a ready-to-integrate unit, our principal hollow rotary table product range remains available.
Custom Industrial Gears for Different Transmission Designs
In addition to gearbox and rotary table components, we can review custom industrial gear manufacturing requests for other transmission equipment. The final manufacturing scope depends on gear geometry, material, inspection requirements and drawing feasibility.
Helical Gears
Helical gears use angled teeth to provide gradual tooth engagement. Applications include speed reducers, industrial drives and precision mechanical transmission systems.

Gear Shafts & Pinions
Machined pinions and integrated gear shafts may include splines, bearing seats, shoulders, keyways and customized connection interfaces.
Keywords: Custom Gear Shafts
Spur Gears
Spur gears have straight teeth parallel to the gear axis. They are used in a variety of parallel-shaft reduction and motion transmission mechanisms.
Keywords: Precision Spur Gears
Spiral Bevel Gears
Spiral bevel gears can be used in angled transmission arrangements, commonly for intersecting shafts. Hypoid gear applications may also be reviewed separately where shaft-offset geometry is required.
Keywords: Spiral Bevel GearsOther gear types, including worm gears, racks and pinions, double helical gears and specialized tooth forms, may be evaluated on a drawing-by-drawing basis. The images above represent distinct gear types and do not imply identical manufacturing specifications.
Custom Gear Manufacturing for Industrial OEM Projects
Custom gear manufacturing starts with understanding the gear’s operating environment and mechanical requirements. A part that appears similar in shape may have very different tooth geometry, accuracy, material and heat-treatment requirements.
We evaluate drawing-based orders for industrial gears and precision-machined transmission parts. Our review considers the intended gear mesh, mounting interface, quantity and required verification methods before a quotation is confirmed.
Whether the application is a replacement component, a prototype drive assembly or a production program, providing the complete engineering requirements helps prevent dimensional and compatibility issues.

Common questions about custom industrial gear production, drawings, compatibility and complete gearbox assemblies.
Can you manufacture individual gears instead of complete gearboxes?
Yes. We can evaluate separate gear and related precision component requests based on drawings, samples and manufacturing feasibility. Complete planetary gearboxes and hollow rotary tables remain our core product offerings.
What gear types can you evaluate for custom manufacturing?
Our review scope includes selected spur gears, helical gears, internal ring gears, external gear rings, pinions, gear shafts, planetary gear components and other specialized transmission gears. Final capability depends on the design and specified requirements.
What information is needed for a custom gear quotation?
Please provide technical drawings or STEP files, gear geometry, material, heat treatment, tolerances, required quantity and delivery destination. Information about the mating components is helpful for checking compatibility.
Can you reproduce a gear based only on a sample?
Samples may support an initial engineering review, but a sample alone may not reveal every critical feature, including original tooth modifications, material specification, hardness and dimensional tolerances. Additional information or inspection may be required.
Do you supply hypoid gears and spiral bevel gears?
Spiral bevel and hypoid gear requests can be reviewed against the specific shaft arrangement, tooth geometry, material and manufacturing requirements. These gear types are not interchangeable, so the appropriate technical drawing is important.
Can I purchase a complete planetary gearbox or hollow rotary table?
Yes. Planetary gearboxes and hollow rotary tables are our principal product categories. You can explore the complete product pages and send the motor or application specifications to our team for selection assistance.
