Welcome to Henan San Kuang Machinery Technology Co., Ltd. – your trusted partner for high-precision power transmission components. Since 2014, we have been dedicated to manufacturing OEM Customized Servo Shaft Couplings with multiple bore size options. Our factory, spanning 10,000–30,000 square meters, is equipped with advanced CNC machining centers and a skilled team of 51–100 employees. With an annual export value of US$2.5–5 million, we serve global markets across North America, Europe, Asia, and Oceania. Our couplings are designed to deliver zero backlash, high torsional stiffness, and reliable performance for demanding servo applications.
This servo shaft coupling is engineered to connect servo motors, stepper motors, and encoders to lead screws, ball screws, or shafts. The key advantage is its multiple bore size availability – we can customize the inner diameter to match your exact shaft dimensions, eliminating the need for adapters or modifications. Whether you need a flexible beam coupling, a rigid clamp coupling, or a bellows coupling, we can tailor the design to your application requirements.
Product Features & Technical Specifications
Zero Backlash Design: Ensures precise positioning and repeatability in servo systems.
High Torsional Stiffness: Minimizes angular deflection under load, maintaining accuracy.
Customizable Bore Sizes: Available from 3mm to 50mm (or larger upon request) with keyway or set screw fixation.
Material Options: High-strength aluminum alloy (7075-T6) for lightweight, low inertia; stainless steel (304/316) for corrosive environments.
Low Moment of Inertia: Ideal for high-speed servo applications, reducing dynamic load.
Excellent Misalignment Compensation: Accommodates parallel, angular, and axial misalignments, protecting bearings and seals.
RoHS & REACH Compliant: Materials meet environmental standards.
Surface Treatment: Natural, anodized, or black oxide finish available.

Frequently Asked Questions
Q: What bore sizes are available for this servo coupling?
A: We offer customizable bore sizes typically ranging from 3 mm to 50 mm. Other sizes and inch dimensions can be produced upon request. Please provide your shaft diameters for a precise quote.Q: Can I order a coupling with a keyway instead of a set screw?
A: Yes, we can manufacture couplings with keyways, set screws, clamp style, or expandable hubs. Specify your preferred fixation method when ordering.Q: What is the typical lead time for a custom coupling?
A: Standard custom orders are shipped within 7–15 working days. For urgent projects, we can expedite production to 3–5 days upon request and availability.Q: Do you offer free samples for testing?
A: Yes, we provide free samples for evaluation. The buyer is responsible for shipping costs, which can be negotiated for bulk orders. Contact our sales team to arrange.Q: What materials are available for the coupling?
A: Standard materials are high-strength aluminum alloy 7075-T6 and stainless steel 304/316. We also offer other materials like carbon steel, brass, or plastic for special applications. Consult our engineers for recommendations.Q: How do I ensure the coupling will handle my torque requirements?
A: Our couplings are rated for torque from 0.5 Nm to 50 Nm in standard designs. For higher torque, we can modify the outer diameter, length, or use a stronger material. Please provide your application torque and speed data for a customized solution.Q: What is the maximum misalignment the coupling can compensate?
A: Typical values: parallel misalignment up to 0.2 mm, angular up to 1°, and axial up to 0.5 mm. These values depend on the specific design and size. We can also design couplings for higher misalignment if needed.Q: Do you have certifications for quality management?
A: Yes, our factory is certified under ISO9001, ISO14000, ISO16949, and other international standards. We also hold certifications like TL900, QS9000, SA8000, and OHSAS18001. All products are manufactured in compliance with these systems.
