CHPC 63 + CH 05 Worm Gearbox with Pre-Stage Module (ratios 108–300:1)
CHPC 63 pre-stage module (ratio 3:1, IEC 63 B5 motor flange, input shaft/flange 11/140 mm) coupled to a CH 05 worm gearbox — total ratios 108–300:1 in one compact unit, for the slow output speeds a single worm stage cannot reach. Aluminium housings, hollow output shaft with 25 mm bore, keyed; output flanges as the CH 05. Overall length R1 115 mm, pre-stage offset I2 40 mm; the gearbox connected to the pre-stage has the module's Z1 input dimension (11/105); other dimensions as the CH 05. Filled for life with synthetic oil — no oil changes, no maintenance; aluminium housing.
Supplied without motor. Fits an IEC 63 B5 motor (11 mm shaft). Also available on the CHE (free input shaft) and ..P versions of the CH.
How to pick from the table: with a standard 4-pole motor (1400 r/min) the total ratio sets the output speed; P1 is the motor power the catalogue pairs with the row and the output torque is at that power — some ratios are listed with two motor powers. The catalogue notes the installed power is sometimes more than the gear needs — always check the output torque against your load, and ask us if in doubt.

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.
Reading the table
Each row is one total ratio (pre-stage 3:1 × worm stage): output speed at 1400 r/min in, the catalogue's motor power P1 for that row and the output torque at that power. Specify the mounting position of the pre-stage relative to the gearbox when ordering.
