Frequently Asked Questions (FAQ)
Q: What is the maximum torque this coupling can handle for a paper machine conveyor?
A: Our standard design supports up to 5,000 Nm continuous torque. Higher torque capacities are available as a custom option—please provide your specific load data.Q: Can this coupling accommodate both angular and parallel misalignment?
A: Yes. The cardan universal joint design allows angular misalignment up to 15° and can also compensate for minor parallel offsets (depending on the shaft length). For extreme parallel misalignment, we recommend a double-cardan configuration.Q: What materials are used for the coupling cross and bearings?
A: The cross and bearings are typically made of heat-treated alloy steel with needle roller bearings inside. For corrosive environments, stainless steel options are available upon request.Q: Are custom bore sizes and keyways available?
A: Absolutely. We offer custom bore diameters from 20 mm to 150 mm (or larger) and any keyway specification (metric or inch). Just provide the shaft dimensions.Q: How often does the coupling need lubrication?
A: Our couplings come pre-greased with high-temperature lithium grease. Under normal paper mill conditions, relubrication is recommended every 2,000 operating hours or as per your maintenance schedule.Q: Do you have experience supplying to paper mills outside China?
A: Yes. We export to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. Many of our clients are paper and pulp manufacturers.Q: What is the typical lead time for an order?
A: For standard sizes, lead time is approximately 15–25 working days after confirmation. Custom orders may take 25–35 days depending on complexity.Q: Does the coupling come with a warranty?
A: Yes. We provide a 12-month warranty against manufacturing defects from the date of shipment. Extended warranty options are available upon negotiation.
