CHE 06 Worm Gearbox with Motor Flange and Free Input Shaft (Ø25 mm output shaft)

Worm Gearboxes

CHE 06 — the CH worm gearbox with its IEC motor flange plus a free input shaft end on the opposite side — for a hand wheel, an encoder, a brake or a second drive on the input. Aluminium housing, hollow output shaft with 25 mm bore, keyed; foot mounting with the A (feet) body as the catalogue's CHR/CHRE drawings — the ..P flange-output execution is available too. Input shaft Ø18 h6 × 40 mm with M6 centre thread, output 25 H7 hollow bore with 8 mm keyway (body and shaft dimensions on the CHR/CHRE sheet; everything else as the CH 06). Filled for life with synthetic oil — no oil changes, no maintenance; aluminium housing.

Supplied without motor. Fits IEC 71 or 80 or 90 motors (B5 or B14 flange as the CH 06 — only the frames the catalogue lists for each ratio are offered).

How to pick from the table: with a standard 4-pole motor (1400 r/min) the ratio sets the output speed. Choose the row whose output speed and torque match your application, then the flange that matches your motor. The Motor column lists the motors that fit that row — pick yours and the output torque and service factor update to match. More in the Selection Guide tab below.

Product Information

Motor pole count

All table figures assume a 4-pole motor (1400 r/min input) — the standard choice for most applications. A 2-pole motor (2800 r/min) doubles the output speed and a 6-pole motor (900 r/min) reduces it, and the power and torque ratings change with them — if you're running anything other than 4-pole, contact us and we'll size it for you.

Service factor — the number that decides how long your gearbox lives

It's the safety margin between what the gearbox can handle and what the drive asks of it: 1.0 means the gearbox works exactly at its rated limit; higher means reserve capacity — a cooler, quieter drive and a much longer life. As a guide: smooth, steady loads (light conveyors, centrifugal pumps) are fine near 1.0; moderate loads (heavier conveyors, packing machines) deserve 1.3 or more; heavy duty (mixers, bucket elevators, frequent starts, long running hours) should sit at 1.5–2.0.

If the service factor turns red after you pick a motor, that combination is below 1.0 — the motor can overload the gearbox in continuous use. It may be acceptable for light, intermittent duty, but for anything continuous choose a smaller motor, a different ratio, or the next gearbox size up — or ask us and we'll size it with you.
