The Hormann SilentDrive SD5500 Head Only Garage Door Opener is an OEM motor unit designed as a direct replacement for the SilentDrive SD5500 operator used on residential sectional garage doors. Engineered for quiet, smooth operation characteristic of the SilentDrive series, this “head only” configuration provides the core powerhead without the rail/track, belt, trolley, door arm, photo-eyes, wall control, or handheld remotes—ideal when the original motor unit needs to be replaced while keeping compatible Hörmann hardware already in place.
This replacement opener head is intended to pair with existing Hörmann/Hormann SilentDrive SD-series rail and accessory systems and is not a universal fit for other brands. For safe, compliant operation, use with compatible Hörmann safety sensors and controls; professional installation is recommended. After mounting the new powerhead, travel limits and force settings must be adjusted on the unit, and any transmitters or keypads should be reprogrammed to the new head per the SD5500 manual. Always verify your current opener label and documentation to confirm SD5500 model compatibility before ordering.
