Fiber Optic Rotary Joint

Fiber is a rotating slip ring built around the envelope you specify and the circuit count you specify. The stator stays with the frame and the rotor turns with the machine, so the wiring on the moving side keeps its connection through unlimited 360° rotation.

Product Overview

Fiber at a Glance

Fiber is a rotating slip ring built around the envelope you specify and the circuit count you specify. The stator stays with the frame and the rotor turns with the machine, so the wiring on the moving side keeps its connection through unlimited 360° rotation.

Key Benefits

What This Model Gives the Machine

Unlimited rotation without cable wind-up

The rotating side keeps its electrical connection through continuous 360° turning, so the machine never has to stop and unwind.

Maintenance-free contact system

Precious metal contact pairs are designed to run without lubrication or servicing for the rated life, so there is nothing to schedule on this axis.

Built to your installation envelope

The mounting interface, lead exit and connector termination are set against your drawing.

Stable transmission under vibration

The contact geometry is designed so that shock and vibration do not translate into resistance variation on the signal rings.

Backed by a 12 month warranty

12 months from date of sale; free repair or replacement for quality problems not caused by human damage

Who It Is For

Engineers Who Specify This Part

Designers of subsea ROV and winch systems, radar and communications antennas, drilling and logging tools, broadcast and surveillance platforms, and defence electro-optical systems.

Application scenarios

Problems It Solves

Three Failures It Removes

Failure 1

Rotation limited to ±180° forces an unwind move into every cycle, and that time is lost on every part the machine makes.

Failure 2

A rotating joint that is not sealed for its environment lets dust or wash water reach the contact surfaces, and the symptom looks like an electrical fault.

Failure 3

Sourcing several rotating joints for one axis multiplies lead times and alignment tolerances.

Manufacturing and Quality Control

How the Unit Is Built and Checked

Machining runs on the in-house CNC centre across roughly 6000 m² of research and production space, and assembly is done by the production team in Jiujiang.

Before despatch each unit is checked for insulation resistance, insulation strength, dynamic resistance variation and functional signal performance, using the test equipment and procedures held under the ISO 9001 and GJB9001C quality systems.

Certifications

  • ISO 9001
  • GJB9001C
  • GB/T 19001-2008 / ISO 9001:2008
Customization Options

What Can Be Changed on This Build

  • Circuit count, and the current and voltage rating of each ring
  • Body diameter, overall length and mounting interface
  • Added channels — Ethernet, USB, HD-SDI, optical fibre, RF coaxial, pneumatic or hydraulic passages
  • Sealing grade from IP51 to IP68, and housing material
  • Lead length, lead specification, connector termination and outlet direction
  • Quality grade S Standard, I Industrial or P Premium against the revolutions expected

Simple customisation 10–20 days. Complex customisation 15–40 days.

Comparison

How It Compares With the Other Formats

The alternative formats are the capsule, the through bore and the separate rotor and brush assembly. Which one is right depends on whether anything has to pass through the centre of the axis and how much space is left around it.

Use Guide

Fitting and Commissioning

Mount the stator, not the load

Fix the stator to the frame through the flange or the anti-rotation arm and couple the rotor to the rotating part. The slip ring must never be used as a bearing — the machine's own bearing carries the load.

Respect the lead route

Leave a service loop at both ends and keep the bend radius above the cable's own minimum. Most field failures start at a lead that was pulled straight.

Separate power and signal runs

Route the power leads and the signal leads apart from each other after they leave the unit, and ground the shield at one end only.

Commission at low speed

Turn the assembly by hand first, check continuity on every circuit, then run up to speed and confirm the signal quality before the machine goes into production.

FAQ

About Fiber

How long does delivery take?

Standard products ship in 7–15 days. Simple customised products take 10–20 days and complex customised products take 15–40 days. The delivery port is Jiujiang, China Mainland.

Can this model be modified for my machine?

Yes. Send the rotating speed, the installation type and size, the circuit count, the voltage and current per ring, the signal types and their parameters, the operating temperature and the IP requirement, and the unit is redesigned around them.
