Henan San Kuang Machinery Technology Co., Ltd. proudly presents our 304 Stainless Steel Disc Coupling – a high-performance solution designed for applications demanding precision, durability, and zero backlash. With a rated torque of 500 Nm and a maximum speed of 6,000 RPM, this coupling undergoes rigorous precision balancing to ensure smooth, vibration-free operation even in the most demanding environments. As a manufacturer with over a decade of experience (since 2014) and a factory spanning 10,000–30,000 sqm, we combine advanced engineering with stringent quality control to deliver couplings that exceed industry expectations.
This disc coupling utilizes a stainless steel diaphragm pack to transmit torque while compensating for misalignment, making it an ideal choice for servo motors, stepper motors, encoders, and other precision motion control systems. The 304 stainless steel construction offers excellent corrosion resistance, strength, and longevity, suitable for clean rooms, food processing, and harsh industrial environments. Our precision balancing process eliminates vibration at high speeds, protecting connected equipment and reducing maintenance costs.

Product Features & Benefits:
Zero Backlash Design: The stainless steel diaphragm pack delivers torsional rigidity with no mechanical play, ensuring precise positioning and repeatability in servo and motion control applications.
Precision Balanced for High-Speed Operation: Each coupling undergoes dynamic balancing to G2.5 grade, minimizing vibration at speeds up to 6,000 RPM. This protects bearings, encoders, and other sensitive components, extending equipment life.
304 Stainless Steel Construction: Resistant to corrosion, chemicals, and moisture, ideal for clean rooms, food & beverage, pharmaceutical, and marine environments. Non-magnetic properties also benefit applications with sensitive magnetic fields.
High Torque Capacity (500 Nm): Suitable for medium to heavy-duty power transmission, handling both constant and intermittent load conditions without failure.
Misalignment Compensation: Corrects angular, parallel, and axial misalignments, reducing installation stress and accommodating thermal expansion.
Maintenance-Free Operation: No wearing parts, no lubrication required – a truly maintenance-free coupling that reduces downtime and total cost of ownership.
Easy Installation: Keyless clamp or set screw hubs (customizable) allow quick mounting on shafts without special tools.
Typical Applications: Our 304 stainless steel disc couplings are widely used in CNC machinery, robotics, printing presses, packaging equipment, textile machinery, test stands, and any servo-driven system requiring high precision and reliability.

Frequently Asked Questions (FAQ)
Q1: What is the maximum angular misalignment this coupling can handle?
A1: Our disc coupling accommodates angular misalignment up to 1 degree (typically ±0.5° continuous), parallel misalignment up to 0.2 mm, and axial movement up to ±0.5 mm. For higher misalignment requirements, please consult our engineering team for custom solutions.
Q2: Can this coupling be used in food processing environments?
A2: Yes, the 304 stainless steel construction is food-grade, corrosion-resistant, and easy to clean. It is suitable for washdown applications and complies with hygienic standards. However, we recommend confirming specific regulatory requirements for your region.
Q3: Do you offer other torque ratings or speeds?
A3: Absolutely. We manufacture a complete range of disc couplings with torques from 10 Nm to over 2000 Nm, and speeds up to 15,000 RPM. Please contact us with your application parameters for a tailored recommendation.
Q4: What bore sizes are available?
A4: Bore sizes are customizable. We can machine bores from 6 mm to 60 mm (or inch sizes) with keyways, set screws, or clamping hubs. Standard options are available, but we always recommend providing your shaft dimensions for a precise fit.
Q5: Is the coupling maintenance-free?
A5: Yes, the disc coupling has no moving parts that require lubrication or adjustment. It is designed for long life with zero maintenance, which reduces downtime and operating costs.
Q6: What is the typical lead time for custom orders?
A6: For quantities up to 100 pieces, lead time is typically 7–15 working days after order confirmation. Larger volumes may require 20–30 working days. We also offer expedited shipping options upon request.
Q7: How do you ensure zero backlash in the coupling design?
A7: Zero backlash is achieved through a preloaded stainless steel diaphragm pack that has no mechanical clearance between the hub and disc. The flexing elements transmit torque without gaps, maintaining constant contact and eliminating any lost motion.
