Since 1952, United Equipment Accessories, Inc. has been a leader in the forestry industry, engineering rotary unions and slip rings to meet the demands of the rugged environment. We are problem solvers. From extreme weather conditions to harsh work conditions, including dust, dirt, and other particles, our custom slip rings and rotary unions can provide durability and longevity for your unique application. UEA engineers work directly with customers to design a custom solution, whether it be a slip ring, rotary union, or combined slip ring + rotary union.
Some of the specifications that set UEA slip ring and rotary union solutions apart include:
- Vibration resistance: Eliminate welds and bolts that can vibrate loose, increased spring pressure on slip rings, and brush studs to eliminate brush jumping
- Robust mounting
- Seals designed for extreme temperatures and high pressures
- Slip ring integrated into the rotary union for protection, assembly savings, and single part number
- Small diameters slip rings for tight dimensional constraints
- IP sealed enclosures
Some of the applications that UEA has created slip ring and rotary union solutions include:
- Felling heads
- Harvesters
- Knuckle boom loaders
- Tracked feller bunches
- Wheeled harvesters
- Forwarders
- Tracked harvesters
- Grapples
- Processing heads
- Shears
- Grapple saws
UEA works with each client to design a solution that fits their unique application. Here are a few examples from forestry customers that we’ve worked with:
Example #1- High Vibration and High Temperature Environment
- Machined flange onto rotary union instead of bolting or welding for high vibrations
- Implemented brush stud and higher spring pressure for high vibrations
- Multiple-piece waterproof design to allow easy access to slip ring
- High-temperature seals for -20°F to 300°F
Example #2- Communication and Dimensional Constraints
- Custom slip ring to fit 1.77” diameter
- Stainless steel enclosure for harsh environment
- Coined silver rings for communication circuits
- IP sealed slip ring enclosure
- Teflon wires used for high temperature, robust design
