Henan San Kuang Machinery Technology Co., Ltd. is proud to present our Customizable Length High Speed Coupling, specifically engineered for demanding automation applications. With over a decade of manufacturing excellence since 2014, we combine cutting-edge technology with rigorous quality control to deliver couplings that meet exact customer requirements. Our product features free technical support and a 12-month warranty, ensuring banks on reliability and performance. Whether you need a standard model or a fully customized solution, our couplings are designed to optimize drive systems in automated production lines, robotic arms, and precision indexing equipment.
The core advantage of our high speed coupling lies in its customizable length, which allows seamless integration into space-constrained or specialized machinery. Unlike fixed-length couplings that limit design flexibility, our solution enables engineers to specify the exact shaft-to-shaft distance, reducing the need for additional adapters or modifications. This adaptability directly translates to faster assembly times, lower inventory costs, and improved system efficiency.
Key Features and Technical Specifications
- High-Speed Capability: Engineered for rotational speeds up to 10,000 RPM (depending on model and size), minimizing vibration and heat generation even under continuous operation.
- Customizable Length: Available in any length from 50 mm to 500 mm (or longer upon request), with tight tolerances (±0.1 mm) for precise fit.
- Material Options: Choose from high-strength steel (alloy or carbon) for heavy torque, or lightweight aluminum for low-inertia applications. Surface treatments include black oxide, zinc plating, or anodizing.
- Zero Backlash: Unique design eliminates mechanical play, ensuring accurate torque transmission – critical for servo-driven automation and CNC machinery.
- Flexible Element: Elastomeric insert (available in polyurethane, Hytrel, or NBR) absorbs shock loads and compensates for minor misalignment, extending equipment life.
- Easy Installation: Clamp-style or keyway connection with pre-drilled bolt holes – reduces assembly time by up to 30% compared to traditional couplings.
- Free Technical Support: Our team of engineers provides application consultation, installation guidance, and troubleshooting via phone, email, or video call – included with every order.
- 12-Month Warranty: Covers defects in materials and workmanship, with fast replacement or repair service. Warranty can be extended upon request.

Benefits for Your Automation Systems
- Reduced Downtime: The robust design and high-speed balancing minimize wear, extending service intervals beyond 20,000 hours under normal conditions.
- Energy Efficiency: Low inertia and zero-backlash contribute to lower power losses – potential energy savings of 5-10% compared to conventional couplings.
- Simplified Logistics: Customizable length means one coupling can replace multiple standard sizes, reducing spare parts inventory by up to 40%.
- Global Compatibility: Available with metric or inch bores, keyway dimensions per DIN, ANSI, JIS, or customer drawing.

Frequently Asked Questions
-
Q: What is the minimum order quantity for customized-length couplings?
A: There is no minimum order quantity for standard customizable options. For fully custom dimensions, we accept orders starting from 10 pieces. Contact our sales team for exact details. -
Q: How long does it take to produce a custom-length coupling?
A: Typical lead time is 15–25 working days after drawing approval. Expedited service is available for urgent orders (7–10 days). -
Q: Can the coupling handle misalignment?
A: Yes, our flexible element design compensates for angular misalignment up to 1°, parallel misalignment up to 0.5 mm, and axial movement up to 2 mm, depending on size. -
Q: Do you provide technical drawings for installation?
A: Yes, we supply 2D CAD drawings and 3D models (STEP, IGES) upon request to facilitate integration into your system. -
Q: What is the warranty coverage?
A: The 12-month warranty covers manufacturing defects. Damage due to improper installation, misuse, or unauthorized modification is not covered. We offer optional extended warranty. -
Q: Can the coupling be used in food processing automation?
A: Yes, if specified, we can manufacture the coupling in stainless steel with FDA-compliant elastomers. Please note that we hold HACCP certification, ensuring suitability for food contact surfaces. -
Q: How do I determine the correct length for my application?
A: Measure the distance between the driving shaft face and driven shaft face. Add any compression allowance (usually 1–3 mm). Our engineers can assist in calculating the ideal length for zero-backlash performance. -
Q: Is free technical support available after purchase?
A: Absolutely. All customers receive free lifetime technical support via email or phone. We also offer on-site support for large orders (travel expenses apply).
