SE Type — Metal End Cap Linear Guide
The SE type replaces the plastic end caps and scrapers with metal parts, with an optional high-temperature rubber wiper. Heat resistance approaches 150 °C, and because there is no plastic or rubber outgassing, it is also the version for vacuum processes. Add /SE to the model code, for example HGW25CA2R1000Z0PII/SE.
Technical highlights
- All-metal end caps and scrapers; the wiper can also be high-temperature rubber
- Heat resistance close to 150 °C
- No plastic or rubber components — suitable for vacuum, no outgassing
- Ordered as a suffix: /SE after the standard model code
- Copper bolt caps C3 to C12 to close the rail mounting holes
Where the SE type is specified
| Equipment | Why metal end caps |
|---|---|
| Diffusion furnaces, bonding machines | Semiconductor processes run hot and must stay clean |
| Heat treatment equipment | Continuous temperature close to 150 °C |
| Vacuum processes | No plastic or rubber parts, so no outgassing |
Copper bolt caps (optional)
| Cap | Screw | Diameter | Thickness |
|---|---|---|---|
| C3 | M3 | 6.15 mm | 1.2 mm |
| C4 | M4 | 7.65 mm | 1.2 mm |
| C5 | M5 | 9.65 mm | 2.8 mm |
| C6 | M6 | 11.15 mm | 2.8 mm |
| C8 | M8 | 14.15 mm | 3.5 mm |
| C12 | M12 / M14 | 20.15 / 23.15 mm | 4 mm |
Where it is used
Semiconductor equipment
Diffusion furnaces and bonding machines, where cleanliness and heat both matter.
Heat treatment
Furnace and oven axes running continuously near 150 °C.
Vacuum processes
No polymer parts means no gas release into the chamber.
Harsh thermal cycling
Metal caps do not embrittle or crack like plastic ones.
