Hebei Speed Torque Transmission Technology Co., Ltd. proudly introduces the High Precision Aluminum Alloy Figure-8 Coupling, specifically engineered for extruder stepping motors. With an ISO9001-certified production facility spanning 3,000-5,000 square meters and an annual export value of US$5-10 million, we combine advanced machining capabilities with rigorous quality control. This coupling delivers exceptional torsional stiffness, zero backlash, and reliable misalignment compensation, making it the ideal choice for demanding extrusion applications. Whether you need standard sizes or custom configurations, our 101-200 skilled employees ensure every component meets the highest standards of precision and durability.
Key Product Features & Advantages:
Premium Material: Manufactured from high-grade aluminum alloy 6061 or 7075 (optional), offering excellent strength-to-weight ratio and corrosion resistance.
Figure-8 Design: The helical cut pattern provides great flexibility while maintaining high torque capacity, effectively absorbing angular, parallel, and axial misalignments.
High Precision: Precision-machined with tight tolerances (ISO 2768-m) ensures minimal runout and consistent performance in high-speed stepper motor setups.
Low Inertia: Lightweight aluminum construction reduces rotational inertia, allowing faster acceleration and deceleration in extruder systems.
Zero Backlash: The one-piece design eliminates backlash, critical for precise motion control in filament extrusion and 3D printing.
Customizable Options: Bore diameters from 3mm to 20mm, lengths, keyways, set screws, and clamp styles are available upon request to fit your specific motor and load shaft.
Surface Finishes: Clear anodized, black anodized, or plain finish to meet environmental requirements.

Frequently Asked Questions (FAQ)
Is this coupling suitable for servo motors as well?
Yes, the Figure-8 design works well with servo motors, especially in low-to-medium torque applications. For higher torque servo systems, we recommend evaluating the specific load requirements.What is the maximum operating temperature?
The aluminum alloy coupling can handle temperatures from -20°C to +80°C under normal conditions. For higher temperature environments, please consult our engineers.Do you offer clamping-style or set-screw fixing?
We provide both options: clamping style (split clamp) for easy installation without damaging shafts, and set-screw style for cost-sensitive applications. Please specify your preference.What about lead time for custom bores?
Standard sizes ship within 7-15 days. Custom bore diameters or lengths typically require 15-25 days, depending on quantity and complexity.Can I get a sample before bulk order?
Absolutely. We offer sample orders with a small fee, refundable upon bulk purchase. This allows you to test the fit and performance.How do I select the correct size for my stepper motor?
Measure the shaft diameter of your motor and the load shaft. Choose a coupling where the bore diameter matches both shafts. If they differ, we can supply stepped bore sizes.Is this coupling RoHS compliant?
Yes, our standard aluminum alloy material and anodized finish comply with RoHS directives. Certificates are available upon request.What if I need very high torque capacity?
For higher torque requirements, we recommend our steel or stainless steel couplings. Our team can help you select the optimal solution.
