Non-Enclosed Slip Ring Assemblies

For the past 60 years Conductix-Wampfler has designed and built rugged slip ring assemblies for industry - first as Industrial Electric Reels (IER), now as part of the Conductix-Wampfler group. Conductix-Wampfler rings are at work in many critical and demanding applications all over the world. We offer standard sizes, with infinite possibilities!

With the modular R-Series slip ring line, you can order customized configurations built from stock components. You truly get a custom-made unit at the price and lead time of an off-the-shelf assembly!

R-Series Slip Rings Feature:

• Reliable brush tracking;  Brushes articulate fore and aft and side-to-side to accurately track the ring
• Long Brush Life; copper graphite and silver graphite "block-style" brushes
• Maximum conductivity; Polished copper alloy and silver plated rings
• Modular brushes and holders; brushes are easy to replace; holders are individually removeable without disturbing other components
• Long lasting, durable construction; strong, engineered plastics are combined with brass and steel hardware
• Ease of installation; Brushes pre-mounted to rigid brush carriage; no need to install the ring piece-by-piece
• Max. Speed: up to 125 rpm, or 500 rpm with optional ball bearings (1.5" bore)

Conductix-Wampfler Slip Rings are specified by bore size and conductor types:

Bore size - The "bore" is the hole through the middle of the assembly that allows it to slide onto the host mounting shaft. Standard sizes:

• 1.5 inch (can be sleeved to a smaller size)
• 2.5 inch (can be factory modified to up to 3.5 inch)
• 4.0 inch (can be factory modified to up to 6.5 inch)
• 8.0 inch (can be factory modified to up to 10.5 inch)

Need a Larger Bore? We've built them at 12", 14", 18", 24" all the way to 40" diameter - see  Custom Slip Rings and  Enclosures.

Need a even larger bore? We can curve our  Conductor Bar to large diameters!

Conductor Types - Each individual ring can be specified to handle the required current and voltage. The different ring ampacities are integrated into a single assembly. We offer these basic types of conductors:

• 15 amps for signals and controls (available up to 4" bore); 250 volts maximum
• 35, 75, 110, 150 (all bore sizes); 600 volts maximum
• 225, 300, 400, or 600 amps for power (2.5" through 8" bores); 600 volts maximum

For higher ampacities see High Ampacity Slip Rings. For higher voltages (up to 25 KV) see  High Voltage Slip Rings. If you have a height restriction, see  Pancake-Style Slip Rings.


If your requirement appears to be outside the standard ranges, be sure to contact Conductix-Wamplfer! We have designed and built thousands of slip ring assemblies for all sorts of applications! See Custom Slip Rings and Enclosures for examples.
