United Equipment Accessories (UEA), based in Waverly, Iowa, has built a strong reputation for designing custom slip rings that keep up with the changing needs of today’s industries. When an application calls for durability or precision in highly technical settings, UEA’s slip rings are built to deliver reliable performance and integrate smoothly into any system.

Where UEA Slip Rings Are Making a Difference
We’ve grouped our applications into four main categories:
- Heavy Equipment & Automation
Think of cranes, excavators, and automated systems. These machines need slip rings that can handle high power, resist vibration, and keep working in tough environments.
- Renewable Energy & Utilities
In wind turbines and irrigation systems, slip rings help manage power and control signals while standing up to weather and long-term use.
- Medical, Surveillance & Robotics
From MRI machines to robotic arms and security cameras, these applications need compact slip rings that transmit clean signals like HD video or Ethernet without interference.
- Marine, Defense & Oil & Gas
Slip rings used in underwater equipment, military vehicles, and offshore rigs must be sealed tight (IP68 rated), handle extreme temperatures, and support complex data and power needs.
Engineering Parameters That Define Performance
UEA slip rings are not one-size-fits-all. Their engineering team tailors each unit to meet specific operational parameters:
- Bore Sizes: Ranging from 0.5″ to 14″, accommodating everything from compact capsules to large through-bore assemblies.
- Circuit Types: Power, signal, Ethernet/CAN, HD video, RF, and fiber optic.
- Brush Technology: Patented brush designs with high contact pressure for superior cleaning and conductivity.
- Environmental Ratings: IP designed for dust, moisture, and submersion; temperature-tolerant for outdoor and marine use.
- Mounting & Maintenance: Custom mounting and wiring designed to fit existing locations available with field-replaceable components.
Custom Solutions for Custom Requirements
What truly sets UEA apart is our commitment to custom engineering and solving complex challenges. Their collaborative approach ensures that every inquiry is met with thoughtful analysis, rapid prototyping, and precision manufacturing.
With decades of experience and a culture of innovation, UEA continues to be the go-to partner for OEMs and integrators seeking high-performance rotary solutions. If your application demands reliability, customization, and engineering excellence, UEA is ready to turn your concept into reality.
