Worm Screw Jack

Worm gear screw jacks are basic lifting components with compact structure, small volume, light weight, wide power sources, no noise, easy installation, flexible use, multiple functions, multiple supporting forms, and high-reliability Long service life, and many other advantages. It can be used individually or in combination, and can accurately control and adjust the lifting or pushing height according to certain procedures. It can be directly driven by a motor or other power, or it can be manually driven. It has different structure types and assembly types, and the lifting height can be customized according to user requirements.

SWL series worm gear screw jacks are widely used in machinery, metallurgy, construction, water conservancy equipment, and other industries. They have many functions, such as lifting, lowering, propelling with the aid of accessories, overturning, and various height and position adjustments.

JW Series Screw Jack Types:

JWM Series Trapezoid Screw Jack JWB Series General Ball Screw Jack
JWM Series Trapezoid Screw Jacks JWB Series Ball Screw Jacks
JWM series trapezoid screw jacks are suitable for low-speed and low-frequency applications. Its main components are a precision trapezoidal screw pair and high-precision worm gear pair.

  1. Economical price, compact structure, simple operation, and convenient maintenance.
  2. Low speed and low frequency: mainly used in places with a heavy load, low speed, and no need to work frequently.
  3. Holding load: trapezoidal screw rod has an automatic locking function, which can hold load even without a brake device.

Note: When subjected to large vibration and impact load, the self-locking function may be invalid. In this case, apply the brake device.

JWB series general ball screw jacks are applicable to high-speed, high-frequency, and high-performance devices. The main components are precision ball screw pairs and high-precision worm gear pairs.

  1. High efficiency: only a small driving source can generate a large driving force
  2. High speed: Compared with a trapezoidal screw rod, the speed is greatly improved, and it can operate easily and at high speed.
  3. Long service life: high-quality ball screw is used to increase its service life by more than 3 times.

Note: Since it has no self-locking function, it is necessary to apply a braking device or select a driving source with braking.
