Rotary Joints and Slip RingsKevlin's rotary joints and slip ringsare passive rotating transmissionlines designed to pass DC and RFsignals between the stationary androtating sections with minimaldegradation. They are true electromechanical devices.
• Products as simple as 1 channel (1 inch long), or as complicated as 33 channels (16 feet long)
• Optional slip rings and encoders
Standard DesignsKevlin's product line contains standard rotary joint designs, available in a wide variety of coaxialand waveguide configurations fordiverse platform applications,including SATCOM terminals,telemetry, test ranges and datalinks. Standard rotary joints aregenerally available with shorter lead times and lower cost than custom products.
Custom Designs
Kevlin is the world’s foremost developer and manufacturer of custom state-of-the-art rotary jointand rotary joint sub-system technology. Kevlin’s engineeringexpertise in custom designs savesour customers considerable effortand expense. Our extensive anddiverse custom design database willallow the selection and modificationof mature designs with proven field history.
• Standard products available for frequency ranges from DC-50 GHz
• Precious metal contacts utilized in wideband coaxial designs for broad-band frequency performance and long life
SATCOM, Telemetry, Test Ranges, Data Links, Radar, Communications, Medical, Commercial & Space
• Precision ball bearing designsemployed in all standard Kevlinproducts for rotational stability and long life

Rotary Joints
Kevlin is currently supplying rotary joints to the
United States FAA and many other countries including
Canada, the United Kingdom, France, Italy, and China.
Most of these are economical, non-developmental units.
Kevlin’s ATC experience in the design and manufacture
of rotary joints has allowed radar system manufacturers
to better penetrate international markets.
Kevlin’s in-house capability includes all the test equipment
necessary to provide a rotary joint that meets or exceeds
the exacting standards required in the ATC marketplace.
This includes complete, in-house, high-power and
environmental test facilities.
Kevlin’s rotary joint subsystems incorporate the latest
designs in rotary joint and slip ring technology as well
as encoder, resolver, and Inductosyn® technology.
Our design and manufacturing experience ensures
the longest operational life obtainable.
