A used circular knitting machine can cut your equipment costs by 40-60% compared to buying new. A single jersey machine that lists at $25,000-$45,000 new can be found for $4,000-$12,000 on the secondhand market. But that savings comes with real risk — a machine with hidden damage can cost more in repairs and downtime than you saved on the purchase price.
This guide covers what actually matters when inspecting a used circular knitting machine. Not generic advice — specific components to check, specific defects to look for, and specific questions that separate a good deal from an expensive mistake.
Why Buy a Used Circular Knitting Machine?
Textile factories buy used machines for three reasons: cost reduction, quick delivery, and replacement parts. A new circular knitting machine from a Chinese manufacturer typically takes 2-4 months to deliver. A used machine from a domestic dealer or local seller can be running in your factory within weeks.
The economics work. A well-maintained used single jersey machine with 3-5 years of service life remaining can produce fabric at the same quality level as a new machine. The key phrase is “well-maintained.” That is what this guide helps you verify.
The used market is active. Platforms like Alibaba list hundreds of used circular knitting machines from Chinese sellers, with prices ranging from $4,000 for basic single jersey units to $15,000+ for computerized jacquard machines. European dealers on platforms like Werktuigen list Mayer & Cie and other premium brands at €4,000-€8,000. IndiaMART carries a wide range of gauges and configurations.
7 Critical Red Flags When Buying Used
1. Rust on the Needle Cylinder and Needles
Rust is the single most common deal-breaker in used machine inspections. Check the needle cylinder first — this is the heart of the machine. Surface rust on the cylinder exterior can be cleaned and polished. Rust inside the needle grooves is a different problem entirely. It means the needles won’t move freely, tension will be inconsistent, and you’ll get dropped stitches across every feeder.
Pull out 10-15 needles at random from different positions around the cylinder. Look for pitting on the needle hooks and latches. Needles with pitted surfaces catch yarn and cause breakage. A full needle replacement for a 30-inch diameter machine runs $25-$50 for a set of basic latch needles, but if the cylinder grooves are also damaged, you’re looking at a $200-$500 cylinder replacement.
What to do: Run your finger along the needle groove surface. If you feel roughness or see discoloration inside the grooves, walk away or negotiate a price that accounts for cylinder replacement.
2. Worn or Damaged Sponge Bar (Needle Retaining Bar)
The sponge bar holds needles in position during knitting. On machines that have seen heavy use, the sponge material compresses, hardens, or tears. A worn sponge bar causes needles to shift during operation, producing uneven fabric and increasing the rate of needle breakage.
This is a relatively cheap part to replace ($15-$30), but its condition tells you about the machine’s overall maintenance history. A machine with a destroyed sponge bar likely has other neglected wear items.
What to do: Press the sponge bar with your thumb. It should feel slightly springy. If it’s hard, cracked, or has visible gaps, factor replacement into your cost calculation.
3. Misaligned Needle Cylinder or Needle Plate
Cylinder alignment affects every stitch the machine produces. A misaligned cylinder causes uneven horizontal stripes in the fabric, inconsistent gauge, and accelerated needle wear. This damage usually comes from improper handling during transport or a crash during operation.
What to do: Rotate the cylinder by hand and watch the needle movement. All needles should rise and fall smoothly with consistent timing. If you see needles that hesitate, jump, or move out of sync with their neighbors, the cylinder or needle plate is likely bent or worn.
4. Inconsistent Yarn Tension Across Feeders
Tension problems are the most expensive issue to diagnose and fix on a used machine. Each feeder on a circular knitting machine has its own tension device. When one feeder’s tension is off, you get visible horizontal lines in the fabric.
What to do: If possible, run the machine with yarn and knit a test fabric. Examine the fabric under good lighting. Look for alternating light and dark horizontal bands. If the seller won’t let you run the machine, ask why. A machine that can’t demonstrate a clean test knit is a machine with problems.
5. Electronic Control System Malfunctions (Computerized Machines)
Computerized circular knitting machines — especially those with electronic jacquard or pattern control — add another layer of inspection. Check the display for error messages. Test the pattern programming by loading a simple design and running it. Check that all sensors respond correctly.
Electronic repairs on imported machines can be expensive and slow. A replacement control board for a Mayer & Cie or Leadsfon machine can cost $500-$2,000 and take weeks to source.
What to do: Power on the machine and run through every menu function. Check that the display is fully readable (no dead pixels or fading). Run a test pattern and verify the machine executes it correctly.
6. Missing or Incomplete Accessories
A circular knitting machine without its full set of accessories is worth significantly less. Missing parts include: ribber attachment, cast-on combs, needle pushers, yarn feeders, creel stands, and the instruction manual. Some of these parts are brand-specific — Brother needles don’t fit Singer machines, and Mayer & Cie ribber clamps won’t work on a Leadsfon.
What to do: Before inspecting the machine, ask the seller for a complete parts list. Cross-reference with the original machine manual (available online for most major brands). Count the feeders — a machine advertised as 90 feeders should have 90 feeders.
7. No Maintenance Records or Service History
A machine without maintenance records is a machine with unknown problems. Regular lubrication, needle replacement, and belt adjustment are the baseline for keeping a circular knitting machine in production-ready condition. A seller who can’t produce any service records is either not the original owner or didn’t maintain the machine.
What to do: Ask for maintenance logs, parts receipts, or at minimum the original purchase invoice. If the seller can’t provide any documentation, reduce your offer by 20-30% to account for the unknown risk.

How to Price a Used Circular Knitting Machine
Used machine pricing depends on brand, age, condition, and market demand. Here are current market benchmarks:
| Machine Type | New Price (China) | Used Price Range | Typical Depreciation |
|---|---|---|---|
| Single Jersey (basic) | $12,000-$25,000 | $4,000-$10,000 | 50-65% |
| Double Jersey / Rib | $20,000-$45,000 | $6,000-$15,000 | 55-70% |
| Computerized Jacquard | $30,000-$70,000 | $8,000-$25,000 | 55-70% |
| European Premium (Mayer & Cie) | $40,000-$80,000 | $8,000-$20,000 | 60-75% |
These are baseline ranges. A machine with documented maintenance, low hours, and complete accessories commands the higher end. A machine with unknown history, visible wear, or missing parts should be at the lower end — or not purchased at all.
Budget an additional $100-$300 for immediate refurbishment: cleaning, new sponge bar, needle inspection, and lubrication. This is standard practice even for machines in good condition.

Questions to Ask the Seller
- What is the brand, model, and year of manufacture?
- How many hours or years of operation has the machine seen?
- What was the machine used to produce (fabric type, yarn type)?
- Has the machine been in continuous service or stored?
- What repairs or part replacements have been done?
- Why are you selling the machine?
- Can I see the machine running and knit a test fabric?
- Do you have the original manual and maintenance records?
- Are all original accessories included?
- What is the final price including loading and transport?
A seller who answers all ten questions clearly and provides documentation is a seller worth doing business with. A seller who deflects or refuses to let you inspect the machine in person is a seller worth avoiding.
Final Thoughts
Buying a used circular knitting machine is a practical way to reduce capital expenditure, but only if you inspect carefully and know what to look for. The seven red flags in this guide — rust, worn sponge bar, misalignment, tension problems, electronic issues, missing accessories, and no documentation — cover the issues that turn a bargain into a liability.
If you’re not confident in your ability to inspect a machine yourself, hire a textile machinery technician to accompany you. A $200-$300 inspection fee is cheap insurance against a $5,000 mistake.
