Frequently Asked Questions
What is the maximum torque this coupling can handle?
Our Heavy Duty Curved Tooth Gear Coupling can handle nominal torque up to 50,000 Nm, with peak torque capacity up to 100,000 Nm (depending on size).Can this coupling accommodate misalignment in mining equipment?
Yes, it compensates for angular misalignment up to 0.5°, parallel misalignment up to 1 mm, and axial misalignment up to 2 mm, reducing stress on connected shafts.What materials are used in manufacturing?
The coupling body and teeth are made of high-strength alloy steel (40Cr) with heat treatment, and the hub is typically made of forged steel for durability.Do you offer custom bore sizes and keyways?
Absolutely. We can customize the bore diameter, keyway dimensions, and overall length to match your specific shaft requirements. Contact us with your specifications.How often should the coupling be lubricated?
Under normal operating conditions, grease lubrication is required every 6 months or after 3,000 operating hours, whichever comes first. For heavy-duty mining applications, more frequent lubrication may be recommended.What certifications do your products have?
Our manufacturing facilities are ISO 9001, ISO 14000, and OHSAS 18001 certified. We can also provide test reports and material certificates upon request.Can I use this coupling for other heavy machinery besides mining?
Yes, it is suitable for various heavy-duty applications including cement mills, steel rolling mills, paper machines, and marine propulsion systems.What is the typical lead time for a standard order?
For standard sizes, lead time is 15-25 working days. Custom orders may take 25-40 working days depending on complexity. We offer expedited shipping options.
