AirTac MGN12H Linear Rails
Looking for premium linear rails without completely emptying your wallet? AirTac rails have quickly become a favourite in the DIY 3D printing community, offering excellent quality, smooth motion, and consistency at a price that’s far more approachable than the highest end alternatives.
These are MGN12H rails fitted with Z2 preload carriages, making them particularly well suited for X-axis rail applications where rigidity and reduced play are important.
Before Installation
AirTac rails are supplied with a grease port for easy maintenance. As with all quality linear rails, they should be:
- Fully cleaned before use
- Properly lubricated with your preferred grease – Temp120 is perfect for this
- Cycled through their full travel after lubrication
This helps remove any residual packing oil and ensures optimal performance from day one.
