Gear Racks
Gear Racks
DIN867 racks for long-travel axes, paired with planetary gearboxes on CNC, laser, and gantry machines. One series: the nine module sizes below are sizes of this rack series — not nine products.

Module table — one series, nine module sizes
Standard DIN module steps inside the catalogue 1.5–10 range. Pitch is module × π, calculated — not a catalogue load table. Per-module load and price are not published in the catalogue; the last column says so. Module sizes are table rows on this series page, not separate product pages.
| Module | Circular pitch (calculated) | Lengths | Load / price per module |
|---|---|---|---|
| 1.5 | 4.71 mm | 500 / 1,000 / 2,000 mm | — (not listed in the catalogue, never zero) |
| 2 | 6.28 mm | 500 / 1,000 / 2,000 mm | — (not listed in the catalogue, never zero) |
| 2.5 | 7.85 mm | 500 / 1,000 / 2,000 mm | — (not listed in the catalogue, never zero) |
| 3 | 9.42 mm | 500 / 1,000 / 2,000 mm | — (not listed in the catalogue, never zero) |
| 4 | 12.57 mm | 500 / 1,000 / 2,000 mm | — (not listed in the catalogue, never zero) |
| 5 | 15.71 mm | 500 / 1,000 / 2,000 mm | — (not listed in the catalogue, never zero) |

Pinion — the mating series
The gear-rack chapter also carries a pinion series (Technical Data of Pinion). A long-travel axis states rack + pinion together, never a rack alone — the pinion has its own series page.
Pairing a long-travel axis
A long-travel axis is three pieces, stated together in one inquiry: gear rack + pinion + planetary gearbox + motor. Your inquiry must state: module, length, straight vs. helical, mounting, load, travel.
Pairing rules
- Pick the module from the axis load and travel — then confirm the pinion and gearbox ratio on the selection page.
- State straight vs. helical and ground finish; the catalogue offers straight and helical, ground.
- State the total travel and whether the axis needs joined rack lengths; joint alignment is to be confirmed by the supplier in writing.
- State materials where the environment demands it: C45 / S45C and 16MnCr5 / SCM440 are the catalogue materials.
- State precision where it matters: DIN 6h25 / 10e27 are the catalogue precision grades.
Installation notes
- Mounting, dowelling and pinion mesh are dimension-sheet items — check the dimension sheet for the exact rack you order.
- Do not assume a rack alone fixes axis accuracy: pinion, gearbox backlash and machine alignment decide together.
- Environment (dust, moisture, temperature) goes in the inquiry; no IP rating is claimed for racks on this site.
