Henan San Kuang Machinery Technology Co., Ltd. proudly presents our Stainless Steel Beam Coupling 8mm to 14mm Bore 2Nm Torque for Encoder, a precision component designed to meet the rigorous demands of encoder and motion control applications. As a manufacturer with a 10,000-30,000 sqm factory and annual export value of US$2.5-5 million, we ensure each coupling delivers reliable performance. This flexible beam coupling offers a perfect balance of torsional stiffness and misalignment compensation, making it an ideal choice for precise shaft connections in automation systems.
Key Features & Technical Specifications
- Material: High-grade 304 stainless steel for excellent corrosion resistance and durability in harsh environments.
- Zero Backlash: One-piece helical beam design eliminates backlash, ensuring accurate position feedback for encoders.
- Misalignment Compensation: Capable of accommodating angular (up to 3°), parallel (up to 0.5mm), and axial (up to 0.5mm) misalignments, protecting sensitive encoder shafts.
- Electrical Isolation: The stainless steel material provides natural electrical isolation, preventing ground loop currents between motor and encoder.
- Easy Installation: Clamp-style or set screw fastening options available for quick and secure mounting.
- Compact & Lightweight: Ideal for space-constrained applications such as servo motors, encoders, and small stepper motors.

Why Choose Our Stainless Steel Beam Coupling?
The beam coupling’s single-piece helical slit design provides a unique combination of flexibility and torsional rigidity. Unlike multi-part couplings, our one-piece construction ensures no moving parts to wear out, offering long service life with minimal maintenance. The 304 stainless steel body resists rust and corrosion, making it suitable for food processing, medical devices, and outdoor equipment. With a torque rating of 2 Nm, this coupling is specifically engineered for encoder and small servo applications where precise torque transmission is critical.
Benefits to Your Application:
- Improved encoder accuracy: Zero backlash ensures no lost motion, preserving position data integrity.
- Reduced wear on shafts: The coupling absorbs vibrations and misalignments, extending bearing and encoder life.
- Simple integration: Standard 8mm to 14mm bore sizes fit common encoder and motor shafts; custom bores available upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the recommended installation torque for the set screws?
A: We recommend a tightening torque of 0.8-1.2 Nm for M4 set screws. Always ensure the shaft is clean and deburred before installation. -
Q: Can this coupling be used between two different shaft sizes?
A: Yes, our coupling can accommodate different bore sizes within the 8-14mm range. Please specify both shaft diameters when ordering. -
Q: Is the coupling electrically conductive?
A: Stainless steel has low electrical conductivity, providing inherent electrical isolation. For applications requiring full insulation, optional anodized finish is available. -
Q: What is the maximum operating temperature?
A: The 304 stainless steel coupling can operate continuously between -40°C and +150°C. For higher temperature environments, consider our special alloy variants. -
Q: Do you offer custom bore sizes or keyways?
A: Yes, we can customize bore sizes, keyways, and clamp configurations. Minimum order quantity may apply for custom versions. -
Q: How does the coupling handle high-speed rotation?
A: For speeds above 3000 rpm, we recommend a balanced version to minimize vibration. Contact our sales team for high-speed applications. -
Q: What is the lead time for large orders?
A: Standard lead time is 7-15 working days. With our factory capacity of 10,000+ sqm, we can handle bulk orders efficiently.
