Ultrafeed Power

Industrial Strength Power

Designed with heavy-duty sewing in mind.

Every Ultrafeed is equipped with a walking foot, features a 3/8″ foot lift, and has a best-in-class needle bar stroke length.

Industrial Strength Power >

Patented Posi-Pin System

The key to full power capacity.

Guarantees a 100% power transfer from the balance wheel to the needle, giving you the power to sew through thick assemblies without causing the machine to abruptly stop while sewing.

Patented Posi-Pin >

Oversize Balance Wheel

Superior slow speed power and control.

Having an oversized balance wheel greatly increases the slow speed power and control of the Ultrafeed with greater torque and the ability for slow, precise stitching.

The Ultrafeed LSZ-1, the blue machine, is a straight and zigzag stitch machine. The LSZ-1 also offers a needle positioning lever, so you can move the needle left, right and center, so you can sew zippers without changing the foot!
