CHMR 090 Worm Gearbox with Input Shaft (Ø35 mm output shaft)
CHMR 090 — the CHM worm gearbox with a solid input shaft instead of the motor flange — for belt, chain or coupling drives, or a motor mounted separately. Aluminium housing, hollow output shaft with 35 mm bore, keyed; optional output flanges (the F executions on the dimension drawing). Input shaft Ø24 j6 × 50 mm with M8 centre thread, key 8 mm (dimensions on the input-shaft sheet; everything else as the CHM 090). Supplied for the B3 mounting position — tell us if you need a different orientation (see the mounting-position drawing). Filled for life with synthetic oil — no oil changes, no maintenance.
How to pick from the table: the figures are for a 1400 r/min input (a 4-pole motor's speed) — the ratio sets the output speed, P1 is the input power the catalogue rates the row at and the service factor is the margin at that power. Drive the input shaft slower or faster and the output speed scales with it; ask us to check the rating if your input speed differs.

Product Information
Reading the table
Each row is one ratio: output speed at 1400 r/min in, the rated input power P1, the output torque at that power and the service factor. Where the catalogue prints a power the gear cannot fully use (marked in the row note), choose by torque, not power.
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.
