SNLThe screw jack, compared to the worm screw jack, boasts high efficiency, ease of adjusting the reduction ratio, and convenient installation and use. It features a compact size, lightweight, a wide range of power sources, no noise, a variety of functions, and high reliability. This series is equipped with an automatic locking function, allowing precise control and adjustment of lifting or advancement height according to a program. The structural forms are diverse, and the lifting height can be customized to meet user requirements..  

SNBScrew Jack,Characterized by ball nuts housed within the casing, utilizing ball screws and nuts, made from hardened alloy steel, and bearing the load between the nut and screw. This rolling action reduces friction between the nut and screw, enabling smooth and efficient movement of the load. Due to enhanced efficiency and rolling performance, ball screws can operate at higher speeds or longer working cycles compared to standard trapezoidal screw lifters.

High-precision screw jacks, suitable for industries like stainless steel precision sheet and wafer panel manufacturing. Space-saving and capable of enhancing high precision and speed, significantly boosting production output.

Features of Screw Jack:

Smooth transmission, noise-free.

2. Low impact vibration.

3. Suitable for low-speed applications and both high and low frequencies.

4. Primarily used for medium to light loads.

5. Maintain Load Capacity: Trapezoidal screw features an automatic locking mechanism, which can retain the load even without a braking device.

6. Safety Setting: To prevent over-travel and damage to the screw and nut, a travel switch is specifically configured.

The screw jack system components include: screw jacks, reducers, motors, reversing switches, drive shafts, couplings, brakes, clutches, etc. As long as the customer provides specific technical requirements, Engineers will provide detailed calculation procedures, system component selection, andCAD Assembly Drawing. Our technical support will be professional. A mature and reliable technical solution will ensure the safety of your equipment.

Ball screw principle:

1. Ball screw lifters, in accordance with the national standard GB/T17587.3-1998 and application examples, are used to convert rotational motion into linear motion; or linear motion into rotational motion, featuring high transmission efficiency and precise positioning.

2. When the ball screw lifting jack acts as the actuator, the nut will convert the rotation angle of the screw into linear motion according to the corresponding pitch specifications. The passive workpiece can be connected to the nut via the nut bracket, thereby achieving the corresponding linear motion.
