Technic ozubené kolo šroub červ dlouhý (32905)

The Technic long worm screw gear (Part 32905) is a specialized mechanical element designed for high-ratio gear reduction. Featuring a Type II axle opening, it mounts securely onto standard axles to drive spur gears at a 90-degree angle. This part is essential for creating high-torque, non-reversible mechanisms where the worm drives the gear, but the gear cannot back-drive the screw.
