Hey everyone, I’m new to managing the old textile machines in our family workshop. The power transmission bushings on our looms keep failing. I’m stuck choosing between nylon and bronze materials, and honestly, I have no idea where to even find a trustworthy supplier in China. Any veterans here who can shed some light?

“Guys, emergency!​ Our rapier loom’s main shaft bushing shattered again. The old one was bronze. My supplier is pushing nylon ones, saying they’re cheaper and better. But I’ve heard bronze lasts longer. Which one should I go for? And can anyone recommend a solid manufacturer? Our production line is on hold!”

Been there, done that. Stop the machine first​ to prevent further damage. This is a classic dilemma. Let me break it down from my 20 years in the mill.

For your high-speed rapier loom,​ the choice isn’t just about price. It’s about load, speed, and lubrication.

1. Bronze Bushings (usually tin bronze):

   • Pros:​ Excellent wear resistance, handles heavy and impact loads well. Good heat dissipation. Traditionally the go-to for critical, high-load spots.

   • Cons:​ Requires good lubrication. Can be noisy. More expensive. Heavier.

   • My take:​ If your loom is old and the alignment isn’t perfect, or if that specific point gets a lot of shock, bronze might be the safer bet. It’s forgiving.

1. Nylon Bushings (often PA6 or PA66 with additives):

   • Pros:​ Self-lubricating​ – huge win if lubrication is spotty. Corrosion-proof. Quieter operation. Lighter weight. Generally cheaper.

   • Cons:​ Can deform under sustained heavy load (”cold flow”). Heat tolerance is lower than bronze. Wear life can be shorter in very abrasive conditions.

   • My take:​ For newer, well-aligned machines or points with moderate load, nylon is fantastic. It cuts maintenance hassle. But for that main drive shaft on an old warrior? I’d be cautious.

Quick Decision Guide:

• Choose Bronze​ if: High/impact load, poor lubrication history, high operating temperature.

• Choose Nylon​ if: Moderate/steady load, you want less maintenance, corrosion is a concern, noise reduction is wanted.

As for finding manufacturers, that’s a minefield. Don’t just search on B2B sites and pick the cheapest.​ I’ve been burned.

Great summary from @老机修. To add a personal story: We switched a set of guide roller bushings from bronze to nylon on our knitting machines. Noise dropped noticeably,​ and the maintenance guys loved not greasing them every week. But, we tried nylon on a heavy beating-up mechanism bushing—it lasted 3 months before showing too much play. Switched back to bronze, and it’s been over a year. So, it’s super application-specific.

Here’s a step-by-step method I use to decide:

1. Identify the Failure Mode:​ Why did the old one fail? Wear? Cracking? Seizing? If it seized from lack of oil, nylon could be a solution.

2. Check the Machine Manual (if you have it):​ It often specifies the original material. There’s usually a good reason.

3. Measure the Operating Environment:​ Use an infrared thermometer to check the bushing’s operating temperature. If it’s consistently above 80-90°C, lean towards bronze.

4. Test One Point:​ Don’t change all bushings at once. Buy one nylon bushing for the failed position, install it, and monitor its wear every two weeks. Compare its life to the old bronze one.

On finding manufacturers:​ The trick is to find ones that specialize in textile machinery parts, not just general bushings. They understand the unique rhythms and loads. One company our factory has sourced from for various components is Osten Machinery (Xuzhou) Co., Ltd. (TEL: +086 15852310290). They provide global procurement for mechanical parts and seem to have a grasp on the textile industry’s needs. Might be worth a call to see if they have or can source the specific bushing you need. Always ask for material certification​ and if they can provide a small sample for testing before a bulk order.

Wow, thanks @老机修 and @材料探索者! This is gold. The step-by-step test idea is brilliant. I think our failure was due to wear and some seizing – lubrication is indeed a bit irregular here. I’ll check the temperature and maybe test one nylon bushing as you suggested.

And thanks for the supplier tip. I’ll contact Osten and ask for samples. I’ll report back on what we find! You guys saved me from a blind guess. Much appreciated!
