Diamond Roll-Ring® Updated Product Data Sheet Now Available

Share Article

A completely revised Roll-Ring® Product Data Sheet is now available as a direct result of additional customer testing and use of new custom Roll-Ring® designs. Mission critical military and aerospace applications continue to dominate the need for custom Roll-Ring® devices. Customers chose Roll-Rings over incumbent slip rings for the long life and shock and vibration benefits of Roll-Rings®. The Product Data Sheet incorporates the customer verified benefits of the Roll-Ring® solution from their applications.

Maintenance Free Long Life Next Generation Slip Ring

For example, a custom Roll-Ring® was recently subjected to 1,000 hours at 1,200 rpm at 0.006” displacement at elevated temperatures for an aircraft application. The incumbent slip ring was capable of performing 100 to 150 hours before requiring replacement. The Roll-Ring® not only survived the 1,000 hours or 72 million revolutions but was able to pass data at 15 MB/s at 30 MHz “flawlessly” throughout the evaluation. The unique design of the Roll-Ring®, a ring of gold plated spring copper captured between two conductive grooves, provides for outstanding vibration resistance.

Shock resistance was verified by testing Roll-Ring® devices to US Navy specifications as well as to NASA specifications. A custom Roll-Ring® device was purchased by the US Navy to replace a slip ring in a radar application aboard capital ships. The Roll-Ring® was built integral to the microwave rotary joint and the entire assembly was subjected to and passed a 180g shock test. Roll-Ring® assemblies built for NASA for the International Space Station to conduct power and data between the solar arrays and the command module was subjected to and passed a 300g shock test.

Naval, land, air and space customers continue to select Diamond Roll-Ring® devices for their mission critical applications where long life and shock and vibration tolerance are important parameters. The updated Roll-Ring® Product Data Sheet incorporates customer results into the existing list of mission critical features and benefits.
