Systems intended for naval use demand high resistance to shock and vibration. The naval environment also requires high corrosion resistance and lightweight solutions are needed to maintain the lowest center of gravity possible.

EVERAXIS offers tailor-made rotating solutions addressing all of these needs while retaining optimal radar performance.

Capsule Slip Rings


Power Capsule Slip Rings

Power Capsule Slip Rings are required wherever high voltage - several kV - or high current - several kA - are transferred between stationary and the rotating platforms. They integrate rotor, stator, bearings and casings.

Electrical Swivels


High Voltage Electrical Swivel

High Voltage Electrical Swivels are specially designed to transfer high power voltages of several tens of kV and high currents of up to 2,000 Amps in harsh offshore oil and gas environments.


Signal and Low Voltage Electrical Swivels

Signal and Low Voltage Electrical Swivels are specially designed to transfer data and power of up to 2,000 Amps for oil and gas applications in harsh marine environments.

Integrated Rotating Systems


Fluid Rotary Joint

EVERAXIS Fluid Rotary Joints are designed to operate at extreme pressure and with high flow. The main application is the cooling of radar antennas such as Active Electronically Scanned Arrays (AESA). Fluid Rotary Joints are commonly integrated into rotary joint systems together with RF rotary joints, FORJ and slip rings.

RF Rotary joints


Waveguide Rotary Joint

Waveguide Rotary Joints are used for the rotary transmission of power and signal between the stationary and rotating parts of a radar or satcom system. EVERAXIS has designed and produced single and multi channel Waveguide (WG) Rotary Joints since 1958. Every new design is simulated in FEM software as well as physically tested for optimal performance. Each high power Waveguide Rotary Joint is tested at maximum peak power before shipment.


Coaxial Rotary Joint

EVERAXIS single and multi channel Rotary Joints are designed to work in rotating 50 Ohm systems, where uninterrupted and low loss signal transfer is required. Coaxial Rotary Joints are compact and lightweight compared to Waveguide Rotary Joints.


Swivel Joint

The Swivel Joint is a special type of RF waveguide joint. It is a joint that is limited in rotation angle, compact in size, with low mechanical torque and high peak power capacity.
