The JWB (Ball Screw Type) is a high-efficiency, energy-saving mechanical actuator designed for medium-speed operations. Its main components include an accurate ball screw and a high-precision worm gear, delivering reliable performance for demanding applications.

Key Features:

  • High Efficiency: Thanks to the ball screw, large thrust can be achieved with minimal driving power, making the jack energy efficient.
  • High Speed: Compared to trapezoidal screw jacks, the ball screw design allows for faster operation, enhancing productivity.
  • Longevity: The use of a durable and reliable ball screw ensures long operating life, making it a cost-effective solution in the long run.
  • Brake Requirement: As the ball screw does not have a self-locking feature, a brake unit is necessary to secure load retention.

Applications:

Ideal for applications requiring high-speed and high-efficiency operations.
Suitable for medium-speed tasks where long-term durability and energy-saving performance are priorities.
The JWB series offers an excellent balance of speed, efficiency, and longevity, making it a reliable choice for various industrial uses.
