Collaborative Engineering: Integrating Slip Rings For Harsh Environments
In defense and aerospace rotary systems, slip ring failure is to be avoided at all costs. Electrical slip ring or fiber optic rotary joint (FORJ) performance is driven by the mechanical environment built around it. Vibration, shock load, thermal cycling, and envelope constraints determine whether a high-bandwidth signal path survives MIL-STD-810H qualification or not.
Engineers managing land combat and transportation vehicle programs can rely on DSTI input to avoid high-impact failures associated with incorrectly interfaced electrical slip rings.
The Rotary Union as an Engineering Platform
Most integration problems start in the same place: fluid and electrical systems designed individually by separate teams, with no collaborative design approach. The hardware functions, but the assembly is unnecessarily heavy, and the parts list is padded with adapters and extra hardware, increasing the number of potential failure points.
Rather than treating the rotary union as a standalone item, we use it as the foundation to consolidate slip rings, encoders, and load-bearing drive mechanisms into a single assembly. Our focus is on lightweight, high-flow, long-life, and low-torque designs optimized for the parent equipment. DSTI specializes in accommodating predetermined interfaces to ensure our approach is a direct fit into an existing design.

Unlocking New Design Possibilities
DSTI specializes in working with integrators to develop a compact stack: a turnkey system that allows hydraulic, pneumatic, and high-bandwidth electrical channels to coexist in a single, space-saving footprint.
When fluid and electrical systems are developed separately, integration gets complex. We look for ways to incorporate scope that traditionally falls outside the rotary union, such as mounting hardware, fluid connections, paint, bearing systems, and more. By optimizing the rotary union envelope to the parent equipment from the start, weight, torque, and reliability compromises are reduced.
