ZBScrew Jack

ZBThe worm gear screw jack offers multiple functions, including lifting, lowering, advancing with accessories, reversing, and adjusting to various height positions.

ZBA worm gear screw jack is a fundamental lifting component featuring a compact structure, small size, light weight, wide power source, noiseless operation, easy installation, flexible use, multiple functions, various mounting options, high reliability, and long service life. It can be used individually or in combination and can accurately control and adjust the lifting or advancing height according to a programmed sequence. It can be powered directly by an electric motor or other power source, or operated manually. It comes in different structural and assembly forms, with lifting heights customizable to the user's requirements.

1.1ZBType(Trapezoidal screw thread)

Low speed, low frequency

ZBType(Trapezoidal screw thread)Suited for low-speed, low-frequency applications,Primary Composition

Components are:Precision trapezoidal screw and high-precision worm and worm gear set.

11.1Economic:

Compact structure, easy operation, and convenient maintenance.

1.1.2Low speed, low frequency:

Primarily used in high-load, low-speed applications where frequent operation is not required.

1.1.3Maintain load capacity:

Trapezoidal screw with automatic locking feature, capable of holding the load even without a braking mechanism. In the event of...

During high vibration or impact loads, the self-locking function may occasionally fail. In such cases, an additional braking device must be used.

1.2JWBType(Standard Ball Screw Type)

High-speed, high-frequency

JWBType(Standard Ball Screw Type)Suitable for high-speed, high-frequency, and high-performance equipment.

The components consist of precision ball screw and high-precision worm gear sets.

12.1High efficiency:

Utilizing rolling friction, the overall efficiency of the machine is enhanced, requiring only a small driving source to generate a significant output.

Driving force.12.2High-speed:Compared to trapezoidal screw threads, there is a significant increase in speed, capable of running smoothly and at high speed

The Earth rotates.

1.2.3Long lifespan:

Utilizing high-quality ball screw for extended service life3Multiple times. Note::No self-locking function built-in,

Additional braking device required or select a drive source with braking capability.

Technical Specifications:|

Anti-rotation structure(UM,DM)

UM:WagerDM:Hanging down

Suited for operation without connection at the top or for winding ropes due to pulleys where rotation prevention is not feasible

Please select the appropriate elevator based on the load direction and installation direction.(UMOrDM)。

Activity Nut Construction(UR,DR)

-In most cases, the elevator must have the travel required due to the lifting action of the screw shaft and the cover for the screw shaft.

Space-efficient, this activity nut construction is highly suitable for increasing travel distance within limited space.

(The screw shaft rotates, the sliding nut moves.)The screw shaft tip is cylindrical, thus in long stroke applications,

Supporting the shaft end in this manner yields excellent transmission effects.

UR:WagerDR:Hanging down

Please consider the load direction,Select the installation direction to choose the appropriate elevator.(Hanging down or pressing up)Note:Selection and Model

In the method of indication, the direction in which the nuts are placed must also be specified.
