Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with a dedicated factory of 3,000–5,000 square meters and over 100 skilled employees, proudly presents our Flexible Snake Spring Grid Coupling with Metallic Elastic Element. This coupling is designed to deliver reliable torque transmission while accommodating misalignment and damping vibrations in demanding drive applications. Combining a robust metallic spring grid with a flexible elastomeric element, it offers exceptional durability and performance for industries ranging from pumps to heavy machinery. Our commitment to quality is backed by ISO9001 certification and a track record of exporting US$5–10 million annually to markets worldwide.
Key Features & Technical Specifications
Snake Spring Grid Design: The metallic spring grid provides high torsional stiffness and excellent shock absorption, reducing peak loads on connected equipment.
Flexible Metallic Element: The elastic element allows for angular, parallel, and axial misalignment compensation, extending the life of bearings and shafts.
Durable Construction: Made from high-strength spring steel and alloy steel, with optional surface treatments for corrosion resistance.
Easy Installation: Split hub design enables quick assembly without special tools, reducing downtime during maintenance.
Customizable Options: Bore sizes, keyway dimensions, and overall length can be tailored to your specific drive requirements.
Wide Application Range: Suitable for conveyors, mixers, crushers, pumps, compressors, and other industrial drives.
Technical Parameters (Typical Values)
| Parameter | Value |
| Torque Capacity (Max) | 5000 Nm (customizable) |
| Bore Diameter Range | 10 mm – 120 mm |
| Maximum Speed | Up to 3600 rpm (depends on size) |
| Misalignment Capacity | Angular: ±1°, Parallel: ±0.5 mm, Axial: ±2 mm |

Frequently Asked Questions
-
Q: What is the maximum torque capacity of this coupling?
A: The torque capacity varies with model size. Our standard range covers up to 5000 Nm, and higher capacities can be engineered upon request. Please provide your operating torque and service factor for a customized solution.
-
Q: Can the coupling accommodate both angular and parallel misalignment?
A: Yes. The flexible snake spring grid design allows for angular misalignment up to ±1°, parallel misalignment up to ±0.5 mm, and axial displacement up to ±2 mm. For larger misalignment, please consult our technical team.
-
Q: What materials are used in the construction?
A: The spring grid is made from high-strength spring steel, and the hubs are made from alloy steel. Surface treatments like black oxide or zinc plating are available to enhance corrosion resistance in harsh environments.
-
Q: Is the coupling suitable for high-speed applications?
A: Yes, depending on the size. Our couplings can operate at speeds up to 3600 rpm. For higher speeds, we recommend balancing the coupling assembly, which can be arranged as an option.
-
Q: Do you offer custom bore sizes and keyways?
A: Absolutely. We can machine the bore to your exact shaft diameter, with standard or special keyway dimensions. Minimum order quantities may apply for custom sizes.
-
Q: What is the typical lead time for delivery?
A: For standard sizes, the lead time is 15–25 working days. Custom orders may require 30–45 days. We ship from Shanghai, Tianjin, or Qingdao, depending on your location.
-
Q: How do I install this coupling?
A: The coupling features a split hub design that simplifies installation. Simply slide the hubs onto the shafts, align the grid, and tighten the bolts. Detailed installation instructions are provided with each order.
-
Q: Does your company provide after-sales support?
A: Yes. We offer technical support via email, phone, or video call. Our team can assist with troubleshooting, replacement parts, and maintenance recommendations. All products are covered by a 12-month warranty against manufacturing defects.
