Vertical JW Ball Screw Lift Column

JWMScrew jack

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

JWMA 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, accurately controlling the lifting or advancement height according to a specific program. It can be powered directly by an electric motor or other power sources, or operated manually. It comes in different structural and assembly forms, with the lifting height customizable to meet user requirements.

1.1JWMType(Trapezoidal screw thread)

Low speed, low frequency

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

Parts for:Precision trapezoidal screw and high-precision 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, and infrequent operation environments.

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 external braking device is required.

1.2JWBType(Standard Ball Screw Type)

High-speed, high-frequency

JWBType(Standard Ball Screw Type)Suited for high-speed, high-frequency, and high-performance devices

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

12.1High efficiency:

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

Propulsion.12.2High-speed:Compared to trapezoidal screws, there's a significant increase in speed, allowing for smooth and high-speed operation.

The earth rotates.

1.2.3Long service life:

Utilizing high-quality ball screws to enhance operational lifespan.3Note: Multiple times.:It does not have an automatic locking function.,

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

Technical Specifications:|

Anti-rotation structure(UM,DM)

UM:WagerDM:Hanging down

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

Condition. Please select an 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 generated by the lifting of the screw shaft and the required space for the screw cover.

The space, if you want to increase the travel distance within limited space, the design of this activity nut is highly adaptable.

(The screw shaft rotates, the sliding nut moves.)The screw shaft end is cylindrical, therefore, during long strokes,

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 or Lashing)N/A:Selection and Model

In the method of indication, it is also necessary to specify the orientation of the nut.
