The Diamond Roll-Ring® design is a maintenance-free slip ring alternative for mission-critical military and aerospace applications.

• Maintenance free
• Long life
• Very low torque
• Shock resistant
• Low signal noise
• 0 - 3,000 RPM
• Milliamp to 2400 Amps
• High transfer efficiency
• Custom designs

	Roll-Rings were invented by Pete Jacobson as a substitute for slip rings to solve friction related three axis drift problems in Directional and Attitude gyroscopes for the F-14.
This success led to Pete’s team developing Roll-Ring Power Transfer Modules for the International Space Station.
	Today, Nineteen countries around the globe rely on ATC Roll-Rings for uninterrupted operation. All units fielded to date are still in service and none have required any maintenance of any kind.

Today Roll-Rings are found in an even wider assortment of mission-critical performance applications including gun turrets, missile systems, satellite tracking systems, rotorcraft, and military radar systems. The company is currently working on high current transfer devices for the wind industry, 2,400 amps at 1,800 rpm with 5-year maintenance intervals.
