Frequently Asked Questions
Technical Specifications & Compatibility
Q: What is the taper specification of the center hole? How do you ensure compatibility with our gas lifts?
A: We utilize a precision 1:10 taper (half-angle 1°26′16"). This ensures a tight-tolerance fit with standard gas lifts, effectively preventing wobbling, tilting, or abnormal noise after long-term use.
Q: What is the specification for the caster mounting holes? Is it compatible with mainstream casters?
A: The base comes standard with an international 11mm socket diameter. This ensures that stem casters remain perfectly vertical and secure without tilting after installation.
Q: What are the vertical height and radius measurements of the chair base?
A: The vertical height is 80mm and the radius are 300, 330, 350mm. We provide detailed technical drawings with these measurements to help your R&D team pre-calculate the minimum seat height, ensuring the final chair meets international ergonomic standards.
Structural Strength & Compliance
Q: What is the material composition of this chair base? How is high load capacity guaranteed?
A: The base is manufactured using high-strength aluminum alloy through a one-piece die-casting process. This metallic structure provides superior rigidity and resistance to deformation compared to synthetic materials. It is engineered to withstand higher vertical loads and lateral impacts, ensuring long-term safety in demanding commercial environments.
Procurement, Logistics & Supply Chain Flexibility
Q: What is the Minimum Order Quantity? Do you support bulk exports and provide Certificates of Origin?
A: We fully support large-scale OEM/ODM procurement and possess extensive export experience. As a Taiwan-based manufacturer, we can provide a Certificate of Origin to facilitate your global market strategy, helping you optimize import duties and streamline customs clearance.
Q: Do you offer full chair assembly or knocked-down shipping options?
A: We offer flexible shipping configurations. You may purchase components individually, or entrust us to integrate other parts for complete chair assembly or Knocked-Down shipping. This flexibility is designed to reduce assembly complexity at your end-destination and optimize container space.
