Choosing a used industrial sewing machine for textile and apparel work usually comes down to one question: do you need a flexible feed system or a dedicated chain-stitcher? Between the Consew 28 and the Union Special 51-400, the answer changes how layers feed, how seams look, and how much you pay up front. The Consew is a Japanese-built head; the Union Special is an American-made heavy-duty machine. One is about all-around feed control, the other about repeating the same seam efficiently.
Quick verdict
For most shops that sew varied materials and want better control at the needle, the Consew 28 is the easier recommendation, and the listed price is $310. If your production is mostly pants, jeans, coats, or other seamed garments and you need consistent chain stitching, the Union Special 51-400 is the pragmatic pick at $250, $60 less. Both are used machines, so expect to do normal cleaning and setup.

Where each wins
If you're setting up a general sewing station and want to handle layered or slippery materials without fighting the presser foot, the Consew 28 is the winner. The feed action keeps fabric moving evenly, and the head-only format leaves room for you to build your own setup. A useful batch of extras helps offset the machine's greasy appearance.
If your floor is dedicated to seaming jeans, trousers, pants, or coats, the Union Special 51-400 wins. The needle configuration is set for those operations, and it is made for one demanding job done well.
Product notes
Consew 28 Industrial Sewing Machine, Walking Foot made in Japan by Seiko
This Consew 28 pairs a walking foot with a needle feed, which is the detail that matters if you sew fabrics that want to shift or climb. This unit is the head only, so you supply the table, motor, and any stand you want. It is good and tight but dirty/greasy in the way of an older industrial machine, with a recently installed slide plate and a worn original manual. The deal includes spare needles, bobbins, a bobbin case, factory wrenches, a guide, and presser feet. Pick it for all-around feed control and a starter pile of extras; just be ready to clean the head and mount it yourself.
Industrial Sewing Machine Union Special 51-400 double needle chain
This Union Special 51-400 is an industrial machine set up for double needle chain stitch work, with 3/16 inch between needles. It is suited to jeans, trousers, pants, and coats, with mechanical control and a United States origin. The specialized needle spacing means it is designed to make the same seam over and over rather than serve as a general-purpose lockstitch machine. If your production is repeating chain-stitch seams, this is the machine to choose. The practical limitation is that the fixed twin-needle geometry is not easy to repurpose, and it carries a California Prop 65 warning. Budget time for the usual setup.
Final choice by use case
Pick the Consew 28 when you need the more flexible machine for varied work and you are comfortable mounting and setting up the head yourself. Pick the Union Special 51-400 when your floor is running repeat seam work on denim and trousers and you want a dedicated machine for that line.
