Heavy-Duty Bag Closing Machine Needle for Newlong & Jute/Sack Sewing

Best for packaging units, jute mills, and factories running heavy-duty bag closing machines to stitch thick sacks, jute bags, and multi-layer packaging material.

Why This Needle

Bag closing machines run at speed on tough, thick material, and a mismatched needle bends or breaks under that load. This needle is built for exactly that job — genuine Groz-Beckert stock in the sizes bag-closing workshops actually use, sold in a 25-piece pack so you’re not reordering every few days.

Features

• Genuine Groz-Beckert needle, sold in packs of 25
• Also cross-referenced as UY1973 and 124×2 on international needle charts
• Heavy-gauge construction for clean penetration through thick, multi-layer material
• DRx2 system commonly listed for Newlong DS-series bag closers (DS-2, DS-7, DS-9C)

उपयोग के मामले

• Closing jute and cotton sacks
• Heavy-duty packaging bag stitching in packaging and agriculture industries
• Multi-layer bag material where standard needles bend or break
• Continuous industrial bag-closing production runs

फ़ायदे

• Heavy-gauge build reduces breakage and bending on thick sack material, cutting machine downtime
• Genuine Groz-Beckert stock gives consistent stitch quality across long production runs
• 25-needle pack keeps a working stock on hand for continuous bag-closing lines

मशीन अनुकूलता

If your bag closer’s manual lists UY1973 or 124×2, check the specs table below — it’s the same needle. Running a Newlong NP-7 or NP-7A? Those take a different system, so use the DNx1 bag closer needle for NP-7 & NP-7A. More systems are in our सिलाई मशीन की सुइयाँ range.

Specs

How to Fit This Needle

First, match needle size to your bag material — 25/200 for standard sacks, moving up to 27/300 for thicker, multi-layer bags. Next, loosen the needle clamp screw on your Newlong bag closer and remove the old needle. Then, insert the new needle fully into the clamp, following your machine’s manual for orientation. Finally, tighten the clamp screw and run a test seam on a spare sack before starting production.

पूछे जाने वाले प्रश्न

What machines does this needle fit?

This DRx2 needle is commonly listed for Newlong DS-series bag closers (DS-2, DS-7, DS-9C). It’s also cross-referenced as UY1973 and 124×2 on some needle charts and supplier catalogs — same needle, different naming convention, so check your machine manual against the specs table above.

Which size should I use for jute sacks vs. heavier bags?

For standard jute or cotton sacks, size 25/200 is the common choice. For thicker or multi-layer packaging bags, move up to 26/250 or 27/300 for cleaner penetration without bending.

How many needles come in one pack?

Each pack contains 25 needles, which is the standard pack size for this heavy-duty needle — enough for continuous bag-closing production without frequent reordering.

Is this needle only for Newlong machines?

Suppliers list it for Newlong DS-series bag closers. If you run a different bag closer brand, check your machine’s manual for the needle system code (DRx2, UY1973, or 124×2) before ordering, since we haven’t independently verified fit on other brands.

Bora silai machine mein kaunsi sui lagti hai?

Heavy bori silai machine needles mostly come in two systems: DRx2 (124×2) for Newlong DS-series bag closers, and DNx1 (92×1) for Newlong NP-7 and NP-7A. Pick the system your machine manual lists, then choose the size by sack thickness: 25/200 for standard jute sacks, 26/250 or 27/300 for thicker, multi-layer bags.

Can I use this bag closer needle on a Newlong NP-7 or NP-7A?

No. Newlong NP-7 and NP-7A bag closers use the DNx1 (92×1) system, not DRx2. Order the Groz-Beckert DNx1 needle for NP-7 & NP-7A instead; it is a different needle even though both are sold for bag closing.

Why does my bag closer needle keep breaking or skipping stitches on jute?

The usual causes are a bent or blunt needle, the wrong needle system, a size too fine for the number of sack layers, or a loose clamp screw. Replace the needle first, step up one size on thick multi-layer bags, re-tighten the clamp, and pair it with a matching bag closer thread. Run a test seam before restarting production.
