Diamond Roll-Rings® provide mission critical power transfer for Mandus Group’s Hawkeye 105mm Weapon System, a lightweight, modular, high-performance Howitzer designed to be integrated with many types of combat transportation.

Mandus Group contacted Diamond Roll-Ring® Engineers in the summer of 2011 as their Hawkeye prototype needed a way to enable power transfer for the elevation and azimuth motors on the carriage deck of the weapon under rotation. Speed of delivery was important to Mandus and the team at Diamond Roll-Ring® was able to design and ship a custom Diamond Roll-Ring® device in 5 and ½ weeks after receipt of their purchase order.


Mandus Group’s Hawkeye is designed to be mounted on many types of combat transportation. As such the Diamond Roll-Ring® needed to fit in the small space between the truck’s bed and the bottom of the weapon’s carriage deck. The maintenance-free feature of the Diamond Roll-Ring® technology means that no field maintenance is required for the life of the weapon system. A slip-ring installed in the same location would require the removal of the entire cannon from the vehicle to gain access for service, an undesirable task especially in a hostile environment.

Everyone here at Diamond Roll-Ring® is excited to be part of the Mandus Group’s truly revolutionary weapon system.
