The SHD series is equipped with an ultra-compact barrel structure that includes flanges, providing versatility in installation options: it can be securely mounted at either end with either rigid or flexible output connections.

The SHD-I model represents the pinnacle of flatness, featuring a compact and lightweight design, which makes it particularly well-suited for applications that have stringent thickness requirements for reducers. Conversely, the SHD-III model is designed to accommodate applications needing central threading through the reducer and adhere to tight thickness specifications.
