Gearbox

Provides speed and torque conversions from a rotating power source to another device.

Notes

The Gearbox is a crafted mechanical component that transfers rotational power between devices, used as an ingredient in many advanced industrial machines such as the Cement Kiln, Combustion Engine, Crane, and Excavator. It is produced from metal parts at a crafting station and stacks to 100. Given its role in multiple high-tier machines, keeping a steady supply of gearboxes in town stockpiles helps avoid bottlenecks when assembling heavy equipment.
