Product Introduction – FUJI 2MGKHH012400 Z-Axis Screw (H02 / H02F Working Head)

Part Number:

2MGKHH012400

Product Name:

Z-Axis Ball Screw / Feed Screw

Category:

Precision Mechanical Transmission Component

Applicable Models:

FUJI NXT H02 and H02F Working Heads

Product Overview

The FUJI 2MGKHH012400 is a high-precision Z-axis screw, also referred to as a ball screw or feed screw, used in the H02 and H02F working heads of FUJI NXT SMT placement machines. It is the main mechanical element responsible for driving the up-and-down (Z-axis) movement of the nozzle shaft.

This component converts rotational motion from the Z-axis motor into linear vertical motion, enabling accurate component pickup heights and placement force control.

Key Features

Precision Machined Ball Screw
Provides high accuracy and repeatability in vertical positioning.

Smooth and Low-Friction Movement
Ensures high-speed, vibration-free motion for the Z-axis nozzle unit.

Durable and Wear-Resistant
Made from high-strength, heat-treated alloy steel for long service life under continuous operation.

Supports High-Speed Z-axis Cycles
Designed to handle the fast up/down motion demands of the H02/H02F heads.

Specifications (Typical)

Function in the System

Works in conjunction with:

Z-axis motor
Linear guide rails
Nozzle holder / shaft
Encoder or sensor for Z-position feedback

Controls the vertical stroke of the nozzle to pick components from feeders and place them on the PCB with controlled pressure.

Typical Failure Symptoms

Nozzle stroke irregularities
Vertical misalignment in placement
Mechanical noise during Z movement
Inaccurate placement height or force
Alarm codes related to Z-axis feedback

Maintenance Notes

Clean and relubricate the screw regularly using FUJI-approved grease (e.g., AA6PT00)
Inspect for backlash, wear, or misalignment during head servicing
Always replace with genuine FUJI parts for best fit and performance

Notes:

When replacing the Z-axis screw, it is strongly recommended to inspect or replace nearby parts such as bearings, couplings, and guide blocks.
Use only genuine FUJI parts to ensure precision and reliability.
Apply FUJI-specified grease regularly to maintain performance and reduce wear.
Misalignment or improper lubrication can lead to screw backlash, vibration, or Z-axis positioning errors.

FAQ Guide – FUJI 2MGKHH012400 Z-Axis Screw (H02 / H02F Working Head)

1. What is the function of the FUJI 2MGKHH012400 Z-axis screw?

Answer:
This part is a precision ball screw that converts rotational motion from the Z-axis motor into linear vertical motion of the nozzle holder. It allows the working head to move components up and down during the pick-and-place process.

2. Which working heads use this screw?

Answer:
The screw is designed for:

H02 Working Head
H02F Working Head
Both are part of the FUJI NXT SMT machine series.

3. What components does the Z-axis screw work with?

4. What are signs of screw wear or failure?

Nozzle not moving up/down properly
Irregular or noisy Z-axis movement
Component height errors or pickup failures
Increased placement inaccuracy
Axis-related alarms on the machine

5. How do I maintain or inspect the screw?

Clean the screw of dust and debris regularly
Lubricate using FUJI-recommended grease (e.g., AA6PT00)
Inspect for signs of wear, backlash, or play
Replace if motion becomes uneven, noisy, or delayed

6. Can the screw be replaced independently?

Answer:
Yes. It can be replaced during head servicing. However, care must be taken to:

Properly align the screw and guide
Replace associated bearings or seals if worn
Ensure coupling and motor alignment are correct
Calibrate the Z-axis after installation

8. Related Part Numbers

9. Do I need to re-calibrate after replacement?

Answer:
Yes. After installing a new Z-axis screw, it's essential to re-calibrate the Z-axis travel range and verify placement height accuracy using the machine’s alignment or head-check utilities.

10. Where can I get support or replacements?

Answer:

Through FUJI SMT official distributors
Or certified SMT service providers
Ensure you specify the exact head model (H02 or H02F) and original part number (2MGKHH012400) when ordering.
