Pushing the boundaries
of Large Bore

When performance rhymes with free passage

In the world of slip rings, the concept of “large bore”– or large-diameter central bore -plays a strategic role in many industrial and defense applications. It allows a mechanical shaft, many cables and optical fibers, hydraulic conduit, or complete structures to pass through the center of the Slip Rings. These solutions are essential for equipment such as rotating radars, optronic platforms, heavy machine tools, targeting systems, and naval turrets.

However, this mechanical freedom has long been associated with a constraint: the larger the bore, the more difficult it becomes to ensure reliable high-speed data transfer.

This compromise between diameter and performance has long been a structural constraint that has been difficult to overcome…

Everaxis’ technological response

At Everaxis, our engineering teams have turned this limitation into a major focus for innovation.

Leveraging our expertise in contactless transmission, we have designed a new generation of large-bore slip rings capable of transmitting up to 3 Gbps in full duplex mode, while incorporating a borehole of up to 500 mm in certain configurations.

Our range of Contactless Through Bore Slip Rings eliminates friction, removes wear and tear, reduces maintenance requirements, and enables stable transmission in harsh environments (vibration, EMI, salinity, extreme conditions).

Paving the way for more compact, robust, and intelligent designs

By removing the historical limitations between mechanics and electrical performance, Everaxis allows critical rotary systems to evolve freely. This opens up a whole new range of possibilities for systems engineers and project managers in the defense, space, aerospace, naval, and heavy industry sectors.

At Everaxis, we design customized solutions to meet the most demanding requirements for power and data transmission in complex rotating environments. Explore our range of large-bore slip rings !
