Benefits
Supports Stable Needle-Bar Travel
The guide plate provides a controlled guiding surface for the needle-bar mechanism, helping maintain smooth movement during repeated sewing cycles.
Helps Maintain Multi-Needle Alignment
Multi-needle machines depend on consistent relative needle positioning. A correctly fitted guide plate helps keep the needle-bar mechanism stable during operation.
Heat-Treated Construction
The heat-treated steel construction provides a wear-resistant working component for machines operating under frequent mechanical movement.
Smooth Guide Channel
The polished guide channel creates a smooth contact surface, helping reduce unnecessary friction between the guide and associated moving components.
Accurate Replacement Positioning
The machined mounting holes and adjustment slots allow the replacement component to be positioned correctly within the original guide mechanism.

How To Use
First, switch off the sewing machine and disconnect the power supply before beginning mechanical maintenance.
Next, access the needle-bar guide mechanism and inspect the existing guide plate, mounting points and mating surfaces for wear or damage.
Then, remove the existing guide plate and install the replacement in the original position, ensuring the mounting holes and guide channel are correctly aligned with the machine mechanism.
Finally, manually move the needle-bar mechanism through its complete travel to confirm smooth movement and correct clearance before running the machine slowly with test material.
FAQs
What is a needle bar guide plate used for?
A needle bar guide plate provides a guiding surface that controls the movement of the needle-bar mechanism. On multi-needle machines, stable guidance helps maintain the relative position of multiple needles during repeated sewing cycles.
Is the 69-120 guide plate compatible with Kansai Special machines?
Yes. The supplied application identifies 69-120 / 69120 for Kansai Special DFB-1404, DFB-1408, DFB-1412, DFB-4408, DFB-4412 and DVK-1702 machines, along with compatible 1400/4400-series configurations.
Can a worn guide plate cause needle-bar movement?
Yes. Wear in the guide surface can increase clearance between mating components, allowing unwanted movement or side-play. Inspecting the guide plate is therefore important when a multi-needle machine develops excessive needle-bar movement.
What is the benefit of the polished guide channel?
The polished channel provides a smoother contact surface for the moving mechanism. This helps reduce friction at the guide interface and can limit unnecessary heat and surface wear during repeated operation.
Is this part used for elastic attaching?
Yes. The listed machine applications include multi-needle elastic-attaching operations such as waistband and waistline work. These applications require consistent needle positioning across multiple parallel rows of stitching.
Can this guide plate be used on Siruba VC008?
The supplied compatibility information lists Siruba VC008 as an additional compatible machine. Because machine revisions can differ, compare the existing guide plate’s part number, dimensions and mounting arrangement before ordering.
Can I use this on any multi-needle sewing machine?
No. Multi-needle machines can use different guide-plate dimensions and mounting arrangements. The machine’s general category is not enough to establish compatibility; the existing 69-120 / 69120 reference and physical configuration should be checked.
How do I know when the guide plate needs replacement?
Look for visible grooves, scoring, deformation or excessive clearance around the guide surface. Unusual needle-bar side movement, vibration or inconsistent needle positioning can also indicate wear in the guide mechanism.
Does replacing the guide plate automatically correct needle alignment?
No. The guide plate provides the mechanical guiding surface, but correct installation and machine adjustment are still required. After replacement, the needle-bar movement and clearances should be checked before returning the machine to production.
Should I replace other components at the same time?
Not automatically. Inspect the mating needle-bar components, mounting hardware and related guide surfaces first. Replace additional parts only when they show wear, damage or excessive clearance.
