If you’re sourcing components for aerospace systems, airport cargo platforms, or material handling in food or chemical environments, you already know: off-the-shelf doesn’t always cut it.
At STR Industries, we don’t just move boxes — we help engineers move the world, one load-bearing unit at a time.
This is why we supply custom ball transfer units designed to perform in the most demanding environments. Whether you’re dealing with high heat, corrosive materials, or precision motion under heavy loads — we can help you build the right solution.
Customization That Actually Matters
Our ball transfer units aren’t just available in different sizes — they’re designed to meet your exact application needs. Here’s what that can include:
✅ Material Options
- Stainless Steel (AISI 420): Excellent for outdoor, corrosive, or washdown environments.
- Chrome Steel: For high-load and general industrial use.
- Plastic or Polymer Units: Compliant with NSF/ANSI 51 and EC 10/2011 for food or pharma applications.
- Pressed Steel: Affordable, reliable, and ideal for lighter applications.
✅ Temperature Ratings
- Most ball transfer units perform up to 100°C continuously.
- For more extreme environments (like furnace feed lines or metal processing), we offer units rated up to 150–200°C with all-metal assemblies and no felt seal.
We’ll walk you through which setup works best for your operating temperature and how to avoid load degradation over time.
Built for Heavy-Duty & Specialized Applications
We don’t treat ball transfers like catalog items. Our units are chosen and configured based on how — and where — they’ll be used.
Common environments we support:
- Airport cargo loading platforms
- Automated storage and retrieval systems
- Sliding gates and transport tables in factories
- Robotics, cleanroom environments, and general automation
- Trolleys and transfer lines in food-grade production facilities
- Sheet metal movement in stamping lines
- Custom pallets for pharma or semiconductor handling
Whether you’re working with strict hygienic requirements or high-impact mechanical setups, we’ve got a build for it.
Why Engineers Trust STR Industries
- 🧠 We help you spec the right material and mounting configuration
- 🛠️ We offer non-standard diameters, finishes, and retention systems
- 🌍 We source globally but manage your orders locally
- 📞 We’re reachable. You can actually talk to someone who understands your equipment
We also keep parts in stock for repeat clients with recurring needs — so your lead times don’t turn into line stoppages.
Your Application Deserves More Than a Catalog Item
Most stock suppliers are built for volume — we’re built for fit and function. If you’ve struggled to find BTUs that hold up under your specific use case, stop settling.
We’re not in the business of selling “what’s available.” We’re here to build what works.
