Pricing & Buying Tips 💸
The price of the MGN9 rail set varies depending on the length and block type. Here’s a general guide:
- 🧩 100mm ~ 300mm sets: typically $8 ~ $15 USD
- 🧩 400mm ~ 600mm sets: typically $15 ~ $25 USD
- 🧩 Full 700mm rail with MGN9H: around $28 ~ $35 USD
Buying Tips:
- 🔍 Always check for stainless steel versions if you plan to use them in humid environments.
- 🧰 For quieter operation, go for pre-lubricated blocks.
- 🛠️ Order slightly longer rails than needed—easier to trim than extend.
Remember to match your block (H or C type) to the motion profile and space of your project.
FAQ: Common Questions Answered ❓
What’s the difference between MGN9H and MGN9C blocks?
MGN9H is a longer block with higher load capacity; MGN9C is shorter and fits tighter spaces.
Can I cut the rail to a custom size?
Yes, with a hacksaw or metal cutting tool, but be sure to deburr and clean the cut end thoroughly.
Do I need lubrication out of the box?
Most come pre-lubricated, but it’s always a good idea to add light machine oil before use.
Are these rails noisy during operation?
No, they are known for quiet and smooth motion, especially when properly maintained.
What type of screws should I use for mounting?
M3 or M4 low-profile socket head screws are typically used with these rails.
Are replacement blocks available separately?
Yes, you can purchase MGN9H or MGN9C blocks separately if needed.
