MGN12H Linear Rail Supplier FAQ
Still have questions? Here are the most common inquiries from procurement managers and engineers:
❓ Q: What’s the difference between MGN12H and MGN12?
A: The MGN12H features a higher load capacity (8.3kN vs. 6.2kN) and improved rigidity due to its reinforced carriage design. It’s ideal for heavy-duty applications where MGN12 might flex under load.
❓ Q: Can you provide custom lengths or pre-drilled holes?
A: Absolutely! We offer:
- Cut-to-length: Any length from 100mm to 6000mm (tolerance: ±0.5mm).
- Pre-drilled mounting holes: Standard or custom hole patterns (CAD drawings accepted).
- End machining: Chamfered, tapped, or slotted ends.
❓ Q: What’s your minimum order quantity (MOQ)?
A: No MOQ for stock items (500mm–4000mm lengths). For custom lengths or treatments, the MOQ is 10 units. Free samples are available (shipping costs apply).
