Frequently Asked Questions (FAQ)
-
Q: What materials are available for this coupling?
A: The standard material is high-strength aluminum alloy (6061-T6). For special requirements, we can also manufacture it in stainless steel or other alloys upon request. -
Q: Can I use this coupling at speeds higher than 20,000 RPM?
A: The maximum rated speed is 20,000 RPM. Operating beyond this may cause balance issues or failure. Please contact our engineering team for higher-speed applications. -
Q: How is the coupling installed and maintained?
A: Installation is simple: slide the coupling onto the shafts, tighten the clamp screws evenly with a torque wrench. No special maintenance is required; periodic inspection of screw tightness is recommended. -
Q: What is the bore tolerance?
A: Standard bore tolerance is H7. Custom tolerances can be provided to match your shaft requirements. -
Q: Do you offer custom bore diameters?
A: Yes, we can machine bores from 6 mm up to 20 mm to your exact specification. Please provide the shaft diameter and tolerance requirements. -
Q: What is the delivery time for standard sizes?
A: For standard bore sizes, we typically ship within 7–15 working days after order confirmation. Custom orders may require additional time. -
Q: Does this coupling require any lubrication?
A: No, the coupling is a dry connection. No lubrication is needed, which makes it suitable for clean environments. -
Q: Is the coupling suitable for application with high vibration?
A: Yes, the rigid clamp design and dynamic balance ensure stable operation under moderate vibration. However, for extreme vibration conditions, we recommend using flexible couplings. Our sales team can advise on the best solution.
