Hebei Speed Torque Transmission Technology Co., Ltd. is proud to introduce our high-performance Nylon Sleeve Gear Coupling — a reliable and durable MC Nylon Internal Tooth Flexible Shaft Coupler designed for a wide range of industrial applications. As a manufacturer with over 5 years of experience and an annual export value of US$5–10 million, we deliver couplings that combine advanced engineering with cost-effective solutions. Our MC Nylon gear coupling offers excellent vibration damping, misalignment compensation, and resistance to wear, making it the ideal choice for connecting shafts in pumps, gearboxes, conveyors, and other rotating equipment.
This flexible shaft coupler features precision-machined internal teeth that engage with external gear hubs, providing smooth torque transmission while accommodating angular, parallel, and axial misalignments. The use of MC Nylon (cast nylon) ensures lightweight construction, high strength, and self-lubricating properties, reducing maintenance needs and extending service life. Whether you need a standard bore size or a custom configuration, our factory in Cangzhou, Hebei — spanning 3,000–5,000 square meters and staffed by over 100 skilled workers — is equipped to meet your requirements.
Key Features & Technical Specifications
Material: Premium MC Nylon (cast nylon) with excellent wear resistance and low coefficient of friction.
Tooth Design: Internal spur gear profile ensures positive engagement and high torque capacity.
Flexibility: Accommodates angular misalignment up to 0.5°, parallel misalignment up to 0.2 mm, and axial movement up to 1.5 mm.
Self-lubricating: Reduces need for external lubrication, lowering maintenance costs.
Lightweight: Over 50% lighter than equivalent metal couplings, reducing inertia and stress on bearings.
Chemical Resistance: Resistant to oils, greases, and many solvents — suitable for harsh environments.
Quiet Operation: Nylon dampens vibration and noise compared to all-metal couplings.
Customizable: Bore sizes, keyways, and overall dimensions can be tailored to your exact shaft specifications.

Advantages for Your Application
Cost-Effective: MC Nylon offers a lower price point compared to stainless steel or bronze couplings without sacrificing performance.
Reduced Downtime: The self-lubricating nature minimizes maintenance; the flexible design extends component life by absorbing shocks.
Energy Efficiency: Lower weight and reduced friction lead to less power loss during transmission.
Versatility: Suitable for food processing, packaging, textile, printing, and general industrial machinery.
Easy Installation: Two-piece design with split hubs allows quick assembly without disconnecting shafts.
Backed by our ISO 9001:2015 certified quality management system, every Nylon Sleeve Gear Coupling undergoes rigorous inspection to ensure dimensional accuracy and material integrity. With a factory spanning 3,000–5,000 square meters and a dedicated team of 101–200 employees, we have the capability to fulfill large-volume orders and deliver within tight schedules. Our main markets include North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, and we ship conveniently from Shanghai, Tianjin, or Qingdao ports.

Frequently Asked Questions (FAQ)
Q1: What is MC Nylon and why is it used for gear couplings?
A: MC Nylon (cast nylon) is a high-molecular-weight polyamide with superior mechanical strength, wear resistance, and self-lubrication. It is ideal for gear couplings because it reduces weight, dampens vibration, and operates quietly without external lubrication.
Q2: Can this coupling handle high torque applications?
A: Yes. Our MC Nylon internal tooth couplings are designed to transmit torques from 10 N·m up to 5000 N·m, depending on size. For higher torque requirements, custom designs are available upon request.
Q3: Is the coupling suitable for outdoor or wet environments?
A: MC Nylon exhibits good resistance to moisture, oils, and most chemicals. However, prolonged exposure to strong acids or UV light may affect performance. We recommend consulting with our technical team for specific environmental conditions.
Q4: What types of misalignment can this coupler compensate for?
A: It can accommodate angular misalignment up to 0.5°, parallel misalignment up to 0.2 mm, and axial movement up to 1.5 mm. For larger misalignments, we suggest exploring our other flexible coupling series.
Q5: Do you offer custom bore sizes and keyways?
A: Absolutely. We can machine any bore diameter within the coupling range, and provide keyways according to your shaft dimensions (e.g., metric or inch standards).
Q6: What is the typical lead time for an order?
A: Standard sizes are usually shipped within 7–15 working days. Customized products may require 20–30 working days, depending on complexity and order quantity.
Q7: How do I select the correct coupling size for my application?
A: You need to know the shaft diameters, torque requirements, speed, and misalignment values. Our sales engineers can help you calculate the proper size — simply provide your application details.
Q8: Is this coupling RoHS compliant?
A: Yes, our MC Nylon material is RoHS compliant. If you require additional environmental certifications, we can provide relevant documentation upon request.
