SJB Ball Screw Jack LiftUnique square groove shell design, enhancing heat dissipation capability of the housing, extending the service life of lubricating grease, etc. Selection of nodular cast iron for the housing material, significantly improving the strength and performance of the housing, as well as under high temperaturesWidely applicable at low temperatures. Square tail cover design prevents the lead screw from rotating freely. Advanced processing equipment and assembly techniques ensure high product quality, while innovative design concepts create strong impact resistance and high strength. Low noise, long-lasting, compact products.

2. The high-speed shaft can rotate in both clockwise and counterclockwise directions.
3. Suitable for low-speed, low-frequency applications; primarily composed of: precision trapezoidal screw and nut sets and high-precision worm and worm gear sets.
4. Low speed, low frequency: Mainly used in high-load, low-speed applications that do not require frequent operation.
5. Maintain Load Capacity: The trapezoidal screw features an automatic locking function, which can maintain the load even without a braking device.
Note: Under conditions of significant vibration or impact loads, the self-locking function may fail. In such cases, please add an external braking device.
Technical Specifications:
Speed Enhancement: 150mm/min to 1800mm/min
2. Input Power: 0.55-17.5 kW
The worm screw lifting platform consists of one or more lifting screws, powered by an electric motor (or handwheel) and coordinated with other components for synchronized and smooth lifting.
For screw jack lifting platforms, whether it's a two, three, or four-way drive, we recommend using a single motor to power them as much as possible. This is because each motor has a speed difference per minute, making it difficult to achieve synchronization and stability with multiple drives.
Common combinations of screw jack platforms include two, four, and eight units, etc. Two units are typically linked together.I and T types are available. Compared to the T-type structure where the drive source is in the middle, the elevator experiences more even force distribution, resulting in a more stable transmission effect. Four linked types are available: T, U, and H. The H-type development and 2H-type multi-machine combinations can be chosen, allowing customers to select based on their own installation space and other requirements. For more selection options, please consult our technical staff.
