Hansheng HRTK Series Steel Housing Hollow Rotary Drives
Our HRTK series steel-housing hollow rotary drives are built for demanding industrial applications. The rugged steel structure delivers higher load capacity, impact resistance, and wear durability than aluminum alternatives, ensuring long-term structural integrity and positioning accuracy under heavy torque and continuous operation.
The large hollow shaft enables clean routing of cables, pneumatics, and vacuum lines through the table center, simplifying integration and preventing wear or tangling. Precision bearings guarantee low backlash, high rotational accuracy, and rigid axial load support. These drives are widely used in multi-station indexing tables, robotic joints, packaging and assembly systems, and CNC 4th-axis or rotary table positioning in precision machinery.

HRTK Series Steel Housing Material & Manufacturing Process
The reliability of a hollow rotary drive heavily relies on the structural integrity of its housing. Hansheng utilizes high-grade ductile iron (such as QT500/QT600) or premium carbon steel (C45/40Cr) for our HRTK series housings. Compared to standard aluminum alloys, these ferrous materials offer exceptionally high tensile strength, outstanding fatigue resistance, and natural vibration-damping properties. This robust material selection ensures the housing can absorb heavy shocks and resist deformation under maximum axial and radial loads.
Manufacturing Process of Steel Housings
To achieve micron-level precision and long-term structural stability, each steel housing undergoes a strictly controlled multi-stage process:
Raw Material & Rough Shaping
Certified high-grade ductile iron (QT500/600) or premium carbon steel (C45/40Cr) is selected. Billets are ultrasonically inspected to ensure no internal defects. Rough shapes are produced via precision casting or forging, providing a sound metallurgical foundation.
Stress-Relieving Heat Treatment
After rough machining, housings are normalized at 880°C and tempered at 600°C with controlled cooling. This cycle eliminates residual stress and achieves a uniform hardness of HB 200–250, preventing distortion over long-term service and ensuring dimensional stability.
Precision CNC Machining
Five-axis machining centers, with cutting parameters optimized for ferrous materials, perform critical milling, boring, and turning operations. Bearing journals and mounting faces are finished to IT6 tolerance class, with coaxiality ≤0.005 mm and total runout ≤0.01 mm, guaranteeing perfect alignment and smooth rotation.
Anti-Rust Surface Treatment
Options include black oxidation, electroless nickel plating (thickness 10–20 μm), or high-durability polymer coatings. Nickel-plated parts pass 72‑hour neutral salt spray tests; other coatings are tailored to application environments, effectively resisting moisture and corrosive conditions.
CMM Quality Inspection
Every finished part is measured on a coordinate measuring machine (CMM) in accordance with ISO 1101, verifying flatness, perpendicularity, position, cylindricity, and other geometric tolerances. 100% inspection with temperature compensation ensures each housing strictly conforms to design specifications.
FAQ
Q: Can the HRTK series hollow rotary drives be mounted in any orientation (horizontal, vertical, or inverted)?
A: Yes. Thanks to the high-rigidity steel housing and the premium internal bearings (such as cross-roller or tapered roller bearings), our drives can be installed in horizontal, vertical, or inverted (hanging) orientations. However, please specify your intended mounting orientation when placing an order, as we may need to optimize the internal grease type and sealing arrangement to ensure long-term, leak-free operation.
Q: Are these drives compatible with third-party servo or stepper motors, and how is the motor interface configured?
A: Our hollow rotary drives feature a highly adaptable motor flange system. They are fully compatible with mainstream AC servo motors (such as Panasonic, Yaskawa, Delta, Mitsubishi, etc.) and standard stepper motors. We customize the input flange and coupling to precisely match your motor's shaft diameter, pilot diameter, and bolt circle dimensions before shipment.
Q: How does the steel housing help in handling high overturning (moment) loads?
A: Steel has a significantly higher modulus of elasticity than aluminum, meaning it resists bending and structural deflection under force. When your application encounters a high overturning moment (for instance, in cantilevered or offset load setups), the rigid steel housing prevents microscopic flexing at the bearing seats. This keeps the internal gear components in perfect alignment, eliminating premature wear and maintaining positioning accuracy over time.
Q: What are the lubrication and maintenance requirements for the HRTK series?
A: Every HRTK series hollow rotary drive is pre-lubricated with high-performance, long-life grease at our factory. Under standard operating conditions (indoor ambient temperature, moderate duty cycles), the drive is virtually maintenance-free. For extreme duty-cycle or continuous 24/7 running environments, we recommend inspecting the seals and replenishing the grease every 10,000 operating hours to maximize service life.
