V Slip Ring Series

V-Series Slip Rings: Known for their compact, economical design, the V-Series is ideal for applications requiring up to 600 V and 75 A, with 1.5" bore size. Suitable for environments where compact design and high-speed capability (with ball bearings) are essential.

R-Series Slip Rings: Designed for robust applications, the R-Series offers higher customizability, with a full range of bore sizes (1.5" to 10"), amperages (6.5 to 600 A), and voltages. It features long-life brush wear, high-speed capability, and more enclosure options, including explosion-proof designs.

Conductix-Wampfler manufactures V-Series and R-Series slip rings to National Electric Code (N.E.C.) guidelines, compliant with UL 508, and is rated at 100% duty cycle. Listed units are available upon request.

Standard amperages are 15, 35 and 75 A, please contact the factory for any additional needs.

Standard bore sizes are 1.5"

While our best lead time and pricing is on our standard units, we have full engineering and manufacturing capabilities to meet custom requirements. Contact the factory.

Yes, V-Series and R-Series offer ball bearing options for high-speed operations, ensuring smooth rotation and reduced wear. The R-Series is designed with sealed ball bearings for higher speed capabilities, and the V-Series includes ball bearings as an option for applications that demand it.

V-Series and R-Series, both offer enclosures that meet NEMA 4 (water and dust tight) and NEMA 9 (hazardous location) standards.

R-Series offers specialized enclosures such as:

• Explosion-Proof Revolving Unit (XRU): Cast aluminum enclosure
• Explosion-Proof Swivel Unit (XSU): Rugged cast iron enclosure with painted finish
• Compliance: Class I Division 1, Groups C & D (Zones 0, 1, & 2) and Class II Groups E, F, & G

Both series offer a high degree of customization to meet specific application needs:

V-Series: Customizable conductor count, brush configuration (double brushing recommended for redundancy), and enclosure options based on the environment.

R-Series: Highly customizable, including options for bore size, current, voltage, enclosure materials, hazardous location compliance, and more. Custom slip rings are available for high-amperage and high-voltage applications, with capacities up to 3000 A.

V-Series and R-Series: Built to conform to UL and NEC standards, and comply with requirements for hazardous location applications, including Class I Division 1 and Class II Groups E, F, & G for explosion-proof and hazardous locations.

R-Series: Additional certifications for ATEX compliance in hazardous environments.

Both series are designed for minimal maintenance and reduced downtime:

• Long-life brushes in both V-Series and R-Series reduce wear, ensuring a long operational life.
• Self-contained designs allow for easy servicing and maintenance access.
• For high-speed or high-voltage applications, periodic inspections of the brush wear and conductor rings are recommended.
