Planetary Gearboxes
SPB / PBR
Helical, inline / flange output. High-precision helical line. All figures below are catalogue ranges; per-model values the catalogue does not publish are marked “not listed”, never zero.
One series, two output forms. SPB and PBR are the two output forms of this one series — not two products. Order by series + output form, never by form code alone.

Per-model values
The catalogue does not publish a per-model torque, radial-load, flange or shaft table for this series. The table below says so instead of filling numbers. Check the dimension sheet for the exact frame you order.
| Item | Catalogue value |
|---|---|
| Rated torque per model | — (not listed in the catalogue, never zero) |
| Radial load | — (not listed in the catalogue, never zero) |
| Backlash grade | Helical B1 typically ≤3–5 arcmin, B2 ≤7–12 arcmin (varies by frame) |
| Flange / shaft dimensions | — (not listed in the catalogue, never zero) |
| Dimension-sheet status | Check dimension sheet for the exact frame you order |
