Case Study: Custom Slip Ring Solution for an Entertainment Ride Platform 

Client Overview 

A global theme park operator required a replacement slip ring for a rotating show platform. The existing unit presented issues with service life, cost, and extended lead times. Based on previous successful collaboration, the client selected Fabricast to provide an alternative solution. 

Project Requirements 

The application imposed strict mechanical and electrical constraints, requiring a direct replacement without modification to the existing system. Key requirements included: 

• Larger-than-standard through bore  

• 20-ring electrical interface  

• Transmission of mixed power and low-level control signals  

• No increase in overall assembly height  

• Compatibility with existing mechanical stack-up and cabling  

• Reduced lead time compared to the incumbent supplier  

Technical Challenge 

The project required a compact, high-density slip ring capable of maintaining stable signal transmission and long service life within a fixed envelope. The design needed to integrate into the existing platform while improving service access and part availability. 

Engineered Solution 

Fabricast developed a custom slip ring assembly by combining established design architecture with targeted modifications. The solution incorporated a cast 20-ring rotor to achieve the required circuit density within limited space, along with coin-silver rings paired with silver-graphite brushes to support low electrical noise and extended wear performance. 

A custom through-bore configuration preserved the original mechanical stack-up, while updates to stator wiring and connector layout improved maintenance efficiency and reduced replacement time. The design used proven standard components where possible, helping reduce development and production lead times. 

Design Rationale 

The selected materials and configuration were based on known performance characteristics in rotating applications. By combining standard design elements with application-specific modifications, Fabricast achieved the required electrical performance and mechanical compatibility while maintaining an efficient delivery schedule. 

Results 

The final solution was installed into the existing platform without requiring structural or cabling changes. The customer reduced procurement lead time compared to their previous supplier while maintaining the original system layout and service practices. During operation, the slip ring delivered stable electrical performance across both power and control circuits, supporting consistent platform operation and longer service intervals. 

Conclusion 

Fabricast delivered a solution that met the client’s mechanical, electrical, and scheduling requirements. The project highlights the ability to adapt established designs to specific application constraints while maintaining performance and delivery expectations.
