MG Series
MG Series Miniature Linear Guideway
- Block Type
- Narrow (MGN), Wide (MGW)
- Model Size
- 2 - 15
- Block Length
- Standard (C), Long (H)
- Dynamic Load Rating
- 0.22 [kN] - 8.93 [kN]
The MG series is a miniature linear guideway that comes in a compact size with a Gothic arch contact design that offers high stiffness and high rigidity against moment loads in all directions. The MG series also offers anti-corrosion protection: a stainless steel (M) option, with carbon steel as standard. MGNR and MGWR rails in sizes 2, 3 and 5 are supplied in stainless steel only. The MG series is available in a narrow block type (MGN) and also with an enlarged width (MGW).
Applications
- Semiconductor equipment
- PCB and IC equipment
- Medical equipment
- Robotics
- Measuring equipment
- Automation equipment
- Printers
- Miniature sliding machinery
Variants
MGN is the narrow block and MGW the enlarged-width block; C is the standard block length and H the long block. Unlike the full-size series, these letters describe width and length rather than load rating. Size 5 is supplied only with the outer recirculation module (-O).

Accuracy classes
Three classes, chosen against the accuracy of the equipment; all three are offered on both non-interchangeable and interchangeable types.
- C Normal — General miniature automation where positioning accuracy is not critical.
- H High — The standard step up for equipment that positions repeatedly.
- P Precision — Measuring and semiconductor equipment; height tolerance tightens to ±0.01 mm.
Preload
Three levels from light clearance to light preload; heavier preload trades running clearance for stiffness.
- ZF Light clearance (4-10 µm) — Free-running fit; available in accuracy class C only.
- Z0 Very light preload (0-3 µm clearance) — The general-purpose setting, available in every accuracy class.
- Z1 Light preload (0.02C) — For stiffness-critical axes; not offered on MG2 and MG3.
Dust protection
End seals are standard on every size except MGN2 (optional on MGN3); bottom seals and reinforced caps are added by code after the model number. Bottom seals reduce the clearance under the block, so check H1 against the mounting surface.
- SS End seal — Orders the optional end seals for MGN3; all other sizes include them as standard.
- U Bottom seal — Seals the skirt under the block; offered on sizes 9, 12, 14 and 15.
- RC Reinforced cap — Sturdier caps for the rail mounting holes; optional for MGN12 and MGN15.
Material
Four material builds cover clean, corrosive and cost-driven environments.
- M Stainless steel — The anti-corrosion build for medical, semiconductor and washdown environments.
- HC Carbon steel with hard chrome treatment — Surface-treated corrosion resistance at a carbon-steel price.
- NC Carbon steel with hicoating treatment — Alternative coated build; no symbol in the model number means plain carbon steel.
