R Slip Ring Series
Modular Slip Rings


The R Series Slip Rings are designed to provide a reliable method of transferring electrical power, control signals, or data between stationary and rotating components. Slip rings are essential in applications where rotation is continuous, or where back-and-forth movement occurs, while maintaining uninterrupted electrical connectivity. This makes them critical components in machinery across industries such as manufacturing, robotics, and automation.
The R Series offers a robust and customizable solution, available in various bore sizes, amperages, and voltages to meet diverse operational needs. The slip rings are designed for durability, featuring long-life brushes that minimize wear and ensure extended operation. Additionally, concentric brush carriage alignment helps maintain consistent performance and reliability over time.
Key features of the R Series include:
- Double-brushed assemblies with individual brush springs for consistent electrical contact and improved efficiency
- Sealed ball bearings, which make the slip rings suitable for high-speed applications while reducing friction and extending operational lifespan
- Optional terminal strips for easy and flexible electrical connections
- Minimal downtime during maintenance, with a self-contained design for efficient serviceability
- Customizable enclosures to meet specific environmental or application requirements
The R Series slip rings are designed for ease of integration into various systems and can be customized further with options like hazardous location compliance, high-voltage solutions, fiber optics, and stainless steel components. Whether your operation involves complex machinery, high-speed rotations, or extreme conditions, these slip rings provide a reliable and adaptable solution.
By ensuring uninterrupted electrical connections between rotating and stationary parts, the R Series slip rings help enhance operational efficiency, reduce maintenance needs, and support the longevity of your equipment.
