Key Features

RevolutionAir threading icon

RevolutionAir™ Needle & Looper Threading

Engage the RevolutionAir™ threader, press the button, and the loopers and needles are threaded with air. No tweezers, no threading order to memorize—just fast, consistent setup every time.

Thread delivery icon

Automatic Thread Delivery™ (ATD)

Instead of tension dials, the Acclaim’s ATD system feeds the right amount of thread for each stitch. Enjoy balanced results on knits, wovens, and decorative threads with far less trial and error.

Wave Stitch icon

Exclusive Wave Stitch

Switch to the patented Wave Stitch to add wavy, decorative edges to garments, quilts, and home décor. Mix thread colors and stitch widths for eye-catching, one-of-a-kind finishes.

Wider workspace icon

2" to the Right & Pure Lighting

Enjoy 2" of space to the right of the needle for easier handling of bulkier projects and long seams, plus three bright LED lights that illuminate your stitches, blades, and thread paths.

Differential Feed & Fabric Support

The full-featured single-unit differential feed keeps knits smooth and gathers even, while the Fabric Support System helps maintain stitch width and prevents tunneling on tricky fabrics.

4/3/2-Thread Serging Versatility

Easily switch between 4-, 3-, and 2-thread setups for strong seams, narrow rolled hems, flatlock accents, and more. Built-in rolled hem and two-thread overlock options expand your finishing choices.

With Snap-On feet, a built-in thread cutter, and handy accessory storage, the Acclaim is ready for both everyday construction and high-end finishing.
