Compact MGN12C linear carriage for MGN12 rail, with recirculating balls and four top threads for attaching a moving plate, tool or platform. Its short body enables linear axes with a reduced footprint.
It belongs to the same linear-guide family used in our HPRO printers. It is suitable for 3D printers, light-duty CNC, automation, fixtures and compact mechanisms when installed on a clean, lubricated and correctly aligned rail.
Nominal MGN12C dimensions
| Feature | Nominal dimension |
|---|---|
| Compatible rail | MGN12 |
| Block type | C compact |
| Overall height H | 13 mm |
| Width W | 27 mm |
| Length L | 34.7 mm |
| Transverse spacing B | 20 mm |
| Longitudinal spacing C | 15 mm |
| Top threads | 4 × M3; nominal depth 3.5 mm |
These are nominal MGN geometry dimensions. When replacing a block in an already machined part, physically check height, length, threads and spacing before final assembly. No load rating, accuracy class or preload is stated because those values depend on manufacture and are not certified for this generic reference.
Compatibility and MGN12C versus MGN12H
This carriage is compatible with our MGN12 linear rail. We also offer the long MGN12H carriage, which uses the same rail section but has different dimensions:
- MGN12C: 34.7mm long with 15mm longitudinal thread spacing.
- MGN12H: 45.4mm long with 20mm longitudinal thread spacing.
The C format occupies less space; the H format provides a longer mounting footprint. They are not direct substitutes on a plate with existing holes. Neither carriage can run on MGN7, MGN9 or MGN15 rails.
A third-party MGN12 rail may be geometrically close, but the shared designation alone does not guarantee fit, preload or smoothness. Test it without load before integration.
Transfer and installation without losing balls
- Clean the rail end and remove burrs that could damage the seals.
- Align insert and rail without a step; do not force or tilt the block.
- Slide the carriage slowly onto the rail without exposing the internal raceways.
- Use correctly sized mounting screws: a screw that bottoms in a shallow thread may damage the block.
- Move the axis by hand and correct alignment before powering the motor.
Lubrication and maintenance
Check lubrication before first use. If protective oil is cleaned away, apply a small amount of light lithium-soap grease or a plastic-compatible linear-guide lubricant. Move the block several times to distribute it and remove external excess.
Keep abrasive dust, swarf and filament debris away. Do not use solid-particle lubricants, loosen the end-cap screws or expose plastic parts to prolonged solvent cleaning. Maintenance intervals depend on travel, speed, load and environment.
Plastic-part colour
Current production uses black end caps and plastic parts. A small quantity of earlier stock with green or red parts from the same factory may still be supplied. Colour is cosmetic, does not change the model and is not selectable.
This is for you if
- You need a compact MGN12C carriage for our MGN12 rail.
- Your design uses the 20 × 15mm mounting pattern.
- You can correctly install, align and maintain the linear system.
This is not for you if
- Your design needs the long body and 20 × 20mm pattern of an MGN12H.
- You need another rail section or guaranteed compatibility with a third-party block.
- You require certified preload, accuracy class or load capacity.
Package contents
Supplied as one MGN12C carriage. Rail, mounting screws and other axis components are sold separately.
