How Does a Screw Drive Garage Door Opener Work?
Unlike chain or belt systems, screw drive openers operate using a rotating threaded rod. When the motor turns the screw:
- The carriage moves along the rail.
- The carriage pulls or pushes the garage door.
- Travel limits determine stopping points.
This direct-drive approach provides:
- Faster opening speeds
- Fewer vibration points
- Reduced part count
However, lubrication is critical for smooth performance.
