Reducer Housing Manufacturer | Custom Cast Iron & Steel Gear Reducer Casings

What is a Reducer Housing?

A reducer housing (also called gear reducer casing or speed reducer enclosure) is the structural shell protecting internal gears and bearings in industrial reducers. It ensures precise alignment, lubricant retention, and resistance to shock/vibration in harsh environments like mining, robotics, and wind energy.
