Frequently Asked Questions
-
Q: What does “maintenance-free” mean for this coupling?
A: The needle roller bearings are pre-packed with high-quality grease and sealed for life. No additional lubrication is required during normal operating conditions, reducing maintenance tasks and risk of contamination. -
Q: Can this coupling handle 5000 Nm continuous torque? What about peak torque?
A: Yes, the rated continuous torque is 5000 Nm. It can withstand peak torques up to 1.5 times the rated value for brief periods (e.g., during startup). Please consult our engineers for specific duty cycles. -
Q: What shaft sizes does it accommodate?
A: Standard bore diameters range from 25 mm to 80 mm. Custom bores, keyways, and tolerances are available upon request to match your shafts precisely. -
Q: Is it suitable for high-speed applications?
A: The maximum rotational speed is approximately 3000 rpm, depending on the final bore size and balance requirements. For speeds above 3000 rpm, please contact us for a tailored solution. -
Q: How does it compensate for misalignment?
A: The universal shaft coupling design allows angular misalignment up to ±2°, parallel offset up to ±0.3 mm, and axial movement up to ±1 mm. This flexibility reduces stress on connected equipment. -
Q: What materials and coatings are available?
A: The standard material is case-hardened alloy steel. Options include zinc plating, black oxide, or nickel plating for corrosion resistance in humid or chemical environments. -
Q: Do you provide technical drawings or 3D models?
A: Yes, we offer dimensional drawings and 3D CAD models upon request to facilitate integration into your design. -
Q: What is the typical lead time and shipping method?
A: Lead time depends on order quantity and customization. Standard products are typically dispatched within 15-30 working days. We ship via sea from Shanghai, Tianjin, or Qingdao ports, or air freight for urgent orders.
