Frequently asked

Does it arrive assembled?

Yes — we assemble, calibrate and test-stitch it in Miami before shipping. To protect the machine during freight, the head ships detached from the table; remounting takes minutes and we can walk you through it by phone.

Can I finance it?

Yes. You can split your purchase into monthly payments with Affirm (checking your rate takes seconds and won't affect your credit score), and Synchrony offers special financing on qualifying purchases (subject to credit approval). See your options on the financing page.

Do you ship to Alaska, Hawaii or Puerto Rico?

Puerto Rico: yes. Freight is $150, and it's free on orders of $3,000 or more.
Alaska and Hawaii: parts and accessories ship there fine — USPS or UPS rates are calculated at checkout. But an industrial machine travels on a pallet by freight, and those two states can't be quoted automatically: get in touch before you order and we'll give you a firm price. +1 (954) 681-3894 or contact@suprasewing.com.

Warranty & support?

Yes — on top of the manufacturer's warranty, Supra Sewing backs your machine with our own coverage: 90 days on mechanical defects and 12 months on electrical & electronic parts — and since this is a Speedway, your electrical & electronic parts are covered for 18 months, serviced by our in-house techs in Miami, FL. Support in English & Spanish: +1 (954) 681-3894 or WhatsApp.

Rolled Hem Specialist – “Baby Merrow” Finish

Dedicated 3-thread rolled hem configuration engineered for extra-narrow, dense edges.
Produces that classic “baby merrow” look: tiny, neat, rope-like edge ideal for high-end garments and décor.
Perfect for sheer, lightweight and fine fabrics, as well as many knits where a narrow decorative hem is desired.
Optimized stitch formation for rolled hems only, rather than being a generic overlock converted on the fly.

Smart Automatic Material Adjustment (SW7 Technology)

Like the rest of the SPEEDWAY SW7 family, the SW7-32R2/223 features Smart Automatic Material Adjustment:

Assists in balancing stitch formation as you change fabric type and thickness.
Helps maintain correct relationship between tension, stitch length and differential feed, reducing waviness or tunneling.
Minimizes trial-and-error when going from one fabric to another (e.g. from a light woven scarf to a soft knit ruffle).

This means easier setup, less time lost tuning the machine, and more time actually sewing.

Materials & Applications

The SPEEDWAY SW7-32R2/223 is ideal for light and medium-light fabrics, such as:

Scarves & shawls – ultra-narrow rolled edge on chiffon, georgette, voile and other sheers.
Dresses & blouses – flounces, ruffles, hems and frills with a clean, tiny edge.
Children’s & babywear – delicate hems on knit or woven garments.
Lingerie & sleepwear – soft edges on lightweight fabrics and knits.
Home décor details – decorative edges on napkins, table runners and lightweight decorative pieces.

Whenever you want a fine, decorative rolled edge instead of a standard overlock seam, this is the right machine.
