Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for standard diaphragm discs?
A: For standard sizes, production takes 10–15 working days. Larger quantities or custom orders may require 20–30 days, depending on complexity. -
Q: Can the disc be used in high‑speed applications?
A: Yes, our discs are balanced for speeds up to 10,000 RPM. For higher speeds, we can apply dynamic balancing upon request. -
Q: What materials are available for corrosive environments?
A: We offer stainless steel grades (304, 316, 17‑4PH) and can apply special coatings. Contact our sales team for recommendations. -
Q: Do you provide custom bore sizes and keyways?
A: Absolutely. We can machine bores, keyways, and set screw holes according to your drawings. Custom dimensions are available upon request. -
Q: How does the diaphragm disc compare to a jaw coupling?
A: The diaphragm disc offers higher torsional stiffness, zero backlash, and better misalignment compensation, making it suitable for precision and servo applications. It is also maintenance‑free. -
Q: Is there a minimum order quantity (MOQ)?
A: For standard items, MOQ is 10 pieces. For custom sizes, MOQ may be 50 pieces. We can discuss smaller quantities for trial orders. -
Q: How do you ensure product quality?
A: We follow ISO9001 quality management system. Each disc undergoes dimensional inspection, hardness test, and dynamic balance check before shipment. -
Q: What packaging do you use for export?
A: Discs are individually packed with anti‑rust oil and wrapped in bubble film, then placed in sturdy cartons or wooden crates for sea/air freight.
