Roll-Rings Explained

What are they for?

Diamond Roll-Rings® are maintenance-free slip rings for mission critical applications where long life, maintenance-free, high power, low electrical resistance, low torque and/or high shock tolerance are important performance requirements.
Maintenance Free

Maintenance Free

Unlike slip rings that generate wear debris and require regular service in the field.
Long Life

How do they work?

Diamond Roll-Rings are rings of spring copper that roll between two conductive races and transfer power, signals and data across that interface. The photograph below shows two Roll-Rings that rotate as the inner conductive race also rotates on a center axis. The Roll-Rings Design page shows how a Roll-Ring is constructed.

Where are they used?

Diamond Roll-Rings are used in a wide variety of mission critical applications as an upgrade to traditional slip rings. The US Navy uses Roll-Rings for its SPS-48E and SPS-49 Air Search Radar systems. Nineteen countries use Roll-Rings in Diamond Antenna Rotary Joints in Air Traffic Control radar systems. Roll-Rings are used on the Patriot Missile System. Roll-Rings are used in high voltage industrial applications where slip ring debris cannot be tolerated.
