What a rugged and military slip ring is

A rugged or defence slip ring is a rotary joint designed and qualified for military vehicles, naval platforms, aircraft pods and harsh mobile plant. The electrical construction is similar to an industrial unit, but the housing, bearings, brush design and connectors are engineered for shock, vibration, wide temperature swings, sand, dust and humidity. Many must also meet electromagnetic compatibility requirements and are often built to a customer specification with qualification testing, traceability and controlled configuration.

When engineers choose a rugged and military slip ring

Choose a rugged design when the platform will see sustained vibration, mechanical shock, extreme temperatures or contamination, such as turrets, radar pedestals, EO/IR gimbals, and construction and mining machines. An industrial slip ring may work in a benign enclosure but usually lacks qualification evidence. The trade-offs are cost, weight, longer lead times and documentation effort. Defence programmes also bring export control and configuration management, which the component maker and buyer handle.

How to specify the Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947)

Send these with your enquiry and an engineer can confirm the right Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947) variant or an equivalent:

  • Environmental standard and test levels, such as MIL-STD-810 or a customer specification
  • Shock and vibration profile (g, Hz)
  • Temperature range, operating and storage (°C)
  • EMC requirements, such as MIL-STD-461
  • Power, signal, video and data channels
  • Connectors and cable types
  • Qualification, traceability and documentation needs

Common mistakes to avoid

  • Quoting a standard without the specific test methods and levels that apply
  • Leaving EMC screening and earthing out of the slip ring specification
  • Assuming commercial connectors will survive the vibration profile
  • Starting qualification late, so the programme waits on test results

Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947): frequently asked questions

Can you help replace Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947) or source the original?

Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.

What is the Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947)?

Heavy-duty slip rings for cranes, excavators and aerial platforms, combining high power, CAN/Ethernet data and high-pressure hydraulic passages. Published series figures include circuits 80, current per circuit 500 A, voltage 1,000 V. It is made by Moog Inc.; Specify Motion can help source it or propose an equivalent.

Who makes the Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947)?

The Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947) is made by Moog (Moog Inc.) and is listed here for engineers comparing options. Specify Motion is not affiliated with Moog Inc.; brand names are used only to identify the product.

What is the circuits of the Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947)?

The published series maximum circuits is 80. Individual models and sizes in the Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947) range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.

Is there an alternative to the Moog Mobile equipment slip rings (F 5769 MR, F 7052, F 5892, F 5947)?

We can assess suitable replacement options. Our engineers can review the original model and propose options for your load, speed and environment. An engineer confirms the fit against your application before recommending anything.

What does MIL-STD-810 mean for a slip ring?

MIL-STD-810 is a US Department of Defense test method standard for environmental conditions such as vibration, shock, temperature, humidity, sand and dust. It describes how to test rather than one pass level, so a programme must state which methods and levels apply. A slip ring quoted as tested to MIL-STD-810 should come with the methods, levels and a test report.

Do defence slip rings need export licences?

Some do. Items specially designed for military use can appear on military or dual-use control lists in the UK, EU and US, which may require an export licence. It depends on the design and its end use, not the product type alone. The component maker and the buyer handle classification and licensing, so share the end use and destination early.
