Kansai 45-157 12-Hole Needle Thread Guide

The Kansai 45-157 12-Hole Needle Thread Guide is a genuine part for Kansai DFB-1400/1412 series 12-needle multi-needle elastic and tape attaching machines. It routes each of the twelve top threads individually before they reach the needle bar, keeping tension even across every needle. Best for garment factories running high-needle-count elastic lines where one or more threads are tangling, looping unevenly, or breaking more than the rest.

• Genuine Kansai part number 45-157
• 12 individual holes, one per needle, for the full multi-needle row
• Smooth-edged holes reduce thread fraying and breakage
• Precision spacing matched to the 12-needle bar layout
• Direct OEM fit — no redrilling or adjustment needed

Use Cases

• Replacing a guide with worn, enlarged or burred holes causing uneven thread tension
• Fixing repeated thread breaks concentrated on specific needle positions
• Routine overhaul of a 12-needle DFB-1400/1412 elastic line

Benefits

• Restores even thread tension across all twelve needles, reducing skipped stitches
• Smooth holes cut down on the thread fraying that causes mid-run breaks
• A single guide replacement fixes an issue that otherwise looks like twelve separate tension problems

How To Replace This Thread Guide

1. First, switch off the machine and note the current thread routing through each hole.
2. Next, unthread all twelve needles from this guide.
3. Then, remove the mounting screw and lift away the worn 45-157 guide.
4. After that, fit the replacement guide in the same mounting position.
5. Following this, re-thread each of the twelve needles through its correct hole in sequence.
6. Finally, run a test seam across the full needle row to confirm even tension before full production.

Frequently Asked Questions

How do I know this guide is causing my thread breaks?

If breaks or loose loops cluster around specific needle positions rather than happening randomly across the row, and the guide’s holes show visible wear, grooves or burrs when inspected closely, that points to the guide rather than a tension dial or needle problem.

Does this fit an 8-needle or 4-needle Kansai machine?

No — this guide is drilled for exactly 12 needle positions matching the DFB-1400/1412. A 4-needle machine needs the 45-152 guide instead, and other needle counts use their own matching part number.

Can I clean and reuse a worn guide instead of replacing it?

Cleaning removes lint and residue but doesn’t restore holes that have worn into an oval shape or developed burrs — those cause fraying regardless of how clean the guide is. Once holes show visible wear, replacement is the more reliable fix.

Is re-threading all 12 needles difficult after replacement?

It’s routine for anyone who already threads this machine, but it does take longer than a single-needle repair simply because there are twelve threads to route correctly. Noting the original routing before removing the old guide speeds this up.

Does this ship with COD and pan-India delivery?

Yes, this guide ships pan-India with cash-on-delivery available on eligible orders, along with GST billing for factory buyers.
