CNC Machined Robot Joint Reducer Housing (Harmonic Drive Housing)
Description
Product Overview
Our Precision CNC Machined Split Housing Assembly is engineered for the demanding requirements of industrial automation. Designed as a high-rigidity, two-piece enclosure, it is primarily used to house robot joint reducers (Harmonic Drives), servo motors, and high-precision gearboxes.
This assembly consists of a deep-machined main body (left) and a specialized end cover (right), which lock together to provide an airtight, vibration-resistant, and perfectly aligned housing for sensitive internal components.

Key Features & Structural Highlights
Deep Precision Cavity
The main body features a high-accuracy cylindrical bore machined to tight tolerances (up to ±0.005mm / ±0.0002″), ensuring an interference fit for motor stators or reducer bearings.
Split Enclosure Design
The two-part design allows for easy component assembly and maintenance, while the matching flange faces guarantee secure sealing against dust and debris.
Specialized End Cover
Features a large central through-hole for the output shaft, along with dedicated eccentric mounting points for harmonic drive wave generators or gearbox output mechanisms.
Durable & Lightweight
Manufactured from 6061-T6 Aluminum alloy, offering a perfect balance of high strength, excellent thermal conductivity, and lightweight construction.
Multiple Mounting Options
Includes strategically placed mounting bosses and tapped holes on the flanges for easy integration into robot arms or actuator systems.
