Yes, we offer anti-friction guides and slides in ceramic materials for non-magnetic or ultra-high vacuum environments. The available ceramics used are:
| Type | Material |
|---|---|
| Silicon nitride | Si3N4 |
| Aluminium oxide | Al2O3 |
| Zirconium dioxide | ZrO2 |
For the cage material, we offer stainless steel, POM, PEEK.
For more information about ceramic linear guides, please take a look at our product page.

| AL | Aluminium |
| KZR | POM |
| KKLK | POM |
| JJ | Brass |
| KRE | POM |
| KREV | PEEK |
| HW | Aluminium* |
* Needle roller cage type HW are optionally available in steel or brass cage body.
Cylindrical roller, ball and needle rollers are made from bearing steel 1.3505
Cage for anti-cage creep linear guides: material POM is used for cage type KRE and PEEK is used for cage type KREV.
There are cages available for vacuum and ultra-high vacuum applications. Please contact us for more information about these products.
The stainless steel guides and rolling elements are made of 1.4034 or 1.4112, hardened between 54 and 57 HRC.
The anti-friction guideways (RSD, RSDE, RNG, N/O, M/V) are made of tool steel 1.2842 or bearing steel 1.3505, hardened between 58 and 62 HRC. These high hardness values offer the best wear-resistance over the lifespan. Stainless steel variants are also available (see next question).
| Type | Material | Hardness HRC |
|---|---|---|
| RSD | 1.3505 / 1.2842 | 58-62 |
| RSDE | 1.3505 / 1.2842 | 58-62 |
| RNG | 1.2842 | 58-62 |
| N/O | 1.3505 / 1.2842 | 58-62 |
| M/V | 1.2842 | 58-62 |
