Worm gear linear actuator is composed by:
1. Main housing,
2. Power input screw,
3. Copper worm gears with internal screw thread,
4. All other associative components.

Worm gear linear actuator can be used in various applications:
1. Lifting application platform (can be used in series for simultaneous actuations),
2. Can be used as an adjustment mechanism for extending press rollers.
3. Can be used as a film adjustment mechanism for plastic production machinery.
4. Can be used as an integral heavy object lifting mechanism.
5. Can be used as part of the locking mechanism for a high-temperature furnace enclosing structure.
6. Can be used as a height adjustment mechanism for plastic container injection mould.
7. Can be used on the locking mechanism for water gates. The following table illustrates function comparisons between worm gear linear actuators, hydraulic pistons and pneumatic cylinders.
