Speedway Style L Bobbins — Polyester
Descripción
Descripción
Speedway Style L pre-wound bobbins are factory-wound bobbins in filament polyester 75D/2, sized to the Style L standard and sold individually or by the box of 144. Winding them on a machine under controlled tension puts more thread on the bobbin than you can wind yourself and keeps the tension steady from the first stitch to the last — which is why production shops stopped winding their own. Available in 2 colors. Ships from Miami, FL.
Which machines use Style L bobbins?
Bobbin style is decided by your machine, not by preference. These are the machines documented as using Style L:
| Brand | Models |
|---|---|
| Juki | DDL-105, DDL-115, DDL-127, DDL-541, DDL-543, DDL-555, DDL-5550, DDW-92, DLM series, DNL-415H, DNL-416, DLU-460, TL-98, TL-98Q |
| Dürkopp Adler | 296 |
| Domestic & semi-industrial embroidery | Brother, Janome, Bernina, Tajima, Barudan |
Can I use a Style L or M bobbin instead?
They look alike and they are not. The difference reaches 1.2 mm in diameter and 2.7 mm in height — enough that the wrong one either rubs the hook and stops the machine, or rattles in the bobbin case and skips stitches. Measure before you order.
| Style | Diameter | Height |
|---|---|---|
| A / Class 15 | 0.815" (20.70 mm) | 0.465" (11.81 mm) |
| L | 0.837" (21.26 mm) | 0.359" (9.12 mm) |
| G | 0.861" (21.87 mm) | 0.390" (9.91 mm) |
| M | 1.023" (25.98 mm) | 0.435" (11.05 mm) |
Dimensions published by The Thread Exchange and WBC Industries. Style L is not a Class 15: the two get confused constantly, and the difference is in the height as much as in the diameter.

Frequently Asked Questions
Is Style L the same as Class 15?
No. They differ in both diameter and height, so they are not interchangeable. Class 15 measures 0.815" x 0.465" while Style L measures 0.837" x 0.359". Check your machine before ordering.
Does the bobbin thread have to match the top thread?
Not necessarily the same brand, but it should be the same fibre and a similar size. Mixing polyester on top with nylon underneath gives you two threads that stretch and shrink differently, and the seam puckers or the tension drifts. Same fibre, same or one size finer, is the safe rule.
How many bobbins come in a box?
A full box holds 144 bobbins (1 gross). You can buy them individually or by the box — the volume discount applies automatically at 144.
How do I know which style my machine takes?
Check the compatibility list above, or measure the bobbin currently in your machine and compare it against the dimensions table.
