Frequently Asked Questions (FAQ)
What is the difference between a rigid flange coupling and a flexible coupling?
A rigid flange coupling provides a solid connection with no angular or axial misalignment compensation, ideal for precisely aligned shafts. In contrast, flexible couplings allow some misalignment but may have lower torque capacity.Can I order custom bore sizes and keyways?
Yes, we offer custom machining for bore diameters, keyway dimensions, and keyway positions based on your drawings or specifications. Contact our sales team for details.What materials are used in the YL Series couplings?
We typically use high-quality carbon steel (e.g., C45) or alloy steel (e.g., 40Cr). Stainless steel is also available on request for corrosive environments.How do I install the coupling correctly?
Ensure both shafts are aligned within 0.02 mm radial misalignment. Clean the shaft ends and bore, then slide the coupling halves onto each shaft. Secure with bolts and torque to specified values. Refer to our installation manual for detailed steps.What is the maximum operating temperature?
Standard couplings can work in temperatures from -20°C to +120°C. For higher temperatures, special material or heat treatment can be applied – please inquire.Do you provide balancing services?
Yes, we offer static and dynamic balancing for high-speed applications (e.g., >1500 rpm). Balancing grade is optional and can be specified per ISO grade.How long is the lead time for standard and custom orders?
Standard sizes typically ship within 7-15 days after order confirmation. Custom orders usually require 15-25 days depending on complexity.What certifications do your couplings have?
Our production process is ISO9001 certified. We can also provide material certificates and inspection reports upon request.
