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.
Radars
Radars are a core area of expertise for 3 EVERAXIS sites : Kista, Naples and Le Plessis Robinson.
EVERAXIS provides solutions for all kinds of radars: from low to high frequency, single and multi channel as well as fully integrated complex solutions containing waveguides, RF coaxial, slip rings, FORJ, fluid or azimut position generators.
Radar Slip Rings & Rotary Joints
Radars require the most complex integrated rotary joint assemblies of different technologies: electrical – optical – RF – fluids – cooling medium. All Integrated Systems go through an extensive qualification testing program, which includes shock, vibration, temperature variation, salt fog, EMI and life testing.
EVERAXIS design cycles are highly dependent on customer needs. The EVERAXIS team is nimble and can react quickly to customer needs for DV or prototype hardware. This is why we encourage all customers to engage with us as early as possible in order to perform system level trade studies. The best development programs owe their success to this co-development approach.
EVERAXIS rotary systems connect the rotary part to the fixed part of radar, satcom or electronic warfare systems in high-end complex systems. EVERAXIS works in cooperation with all of the world’s primary military contractors that design and develop advanced radar technologies. EVERAXIS radar solutions are installed in naval, aerospace, air traffic control, land systems and in all climates.
The rotary joint can be found in both military and civilian systems. It is designed to operate continuously in harsh environments, requiring extreme levels of product reliability and quality.
EVERAXIS recently partnered with Raytheon Technologies in the US to develop the first hypersonic defensive system, the Lower Tier Air and Missile Defense Sensor (LTAMDS).

Fiber Optic Rotary Joints
Integrated Fiber Optic Rotary Joints
EVERAXIS has more than 10 years of expertise in optical technologies for high data rate signal transmissions. Integrated Fiber Optic Rotary Joints (FORJ) can be supplied as a stand alone product with customized characteristics (wavelength, connectors, fiber characteristics) or combined into a hybrid opto electric slip ring with contact or contactless technology.
Multi Mode Fiber Optic Rotary Joints
Multi Mode Fiber Optic Rotary Joints (FORJ) can be supplied as a stand alone product with customized features (wavelength, connectors, fiber).
Single Mode Fiber Optic Rotary Joints
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.
Pancake Slip Ring
Dense Capacity Pancake
Using double-sided pancake technology and advanced manufacturing to provide small pitch allows for highly dense numbers of circuits in much smaller packages. EVERAXIS designs and manufactures these types of Dense Capacity Pancake slip rings for various military and aerospace applications.
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.
Waveguide and Coaxial Rotary Joint Assembly
Waveguide and Coaxial Rotary Joints are used for the transmission of power and signal between the locked and rotating parts of a radar or satcom system. Since more than 70 years EVERAXIS has designed and manufactured both single and multi channel Waveguide (WG) and Coaxial Rotary Joints . Each time a new design is needed EVERAXIS will combine simulations in FEM software as well as labtests for optimal performance. Individual high power Waveguide and Coaxial Rotary Joints are tested at maximum peak power before being shipped to the customer. EVERAXIS Waveguide and Coaxial Rotary Joints are well known for their exellent isolation between channels.
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.
Slip Rings Separates
Dense Signal Design Slip Ring Separates
Many applications that have very tight packaging constraints lead to a dense or low pitch. Compressing many signals into a small package requires specialized manufacturing techniques. EVERAXIS has provided dense signal count platters and drums to many aerospace and defence customers over several decades.
