1424 Gear 11/1 Hex 7mm x Square 16mm -- 11:1 worm gear for manually operated rolling shutters
Simu's 1424 gear turns a 7mm hex crank input into a 16mm square output at an 11:1 ratio. Somfy builds it with a nylon composite casing around a hardened steel worm gear, and the factory designation includes an end limit device. Shutter installers use it to repair or build crank-driven rolling shutters.

Common questions
What does the Simu 1424 gear 2002146 do?
It sits between the crank and the shutter axle of a manual rolling shutter. The 2002146 gear takes a 7mm hex crank input and delivers a 16mm square output, reducing effort at an 11:1 ratio. Somfy lists rolling shutters as its application.
What is the gear made of?
Somfy describes the 2002146 as a nylon composite outside casing with a hardened steel worm gear inside. The composite shell keeps weight down, and the steel worm gear carries the load when you crank the shutter up or down.
Does the 2002146 include a limit device?
Yes. Somfy's factory designation for part 2002146 reads 1424 11/1 H07-C16 with end limit device. Check the limit setting on your shutter after you install the gear so the curtain stops at the right open and closed positions.
What warranty covers this gear?
Somfy backs the Simu 1424 gear 2002146 with a 5-year warranty. ShadeMotorsDirect sells it as a genuine Somfy group part, and Somfy publishes the gear on page 63 of the Simu product catalog, linked in the documentation section above.
