Specify Motion is not affiliated with Morgan Advanced Materials plc. Morgan Advanced Materials and Wind turbine generator slip ring assemblies are used only to identify the product. Comparisons use published figures; always confirm against the current datasheet.
Morgan Advanced Materials Wind turbine generator slip ring assemblies replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original Morgan Advanced Materials part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.
Through-bore slip rings with a hollow centre so shafts, pipes or cables can pass through, carrying power, signal and fieldbus data. Standard bores run from 12.7 mm to 100 mm and custom bores are offered.
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
Typical applications
What a through-bore slip ring is
A through-bore slip ring is a rotary electrical joint built around a hollow centre, so a drive shaft, pneumatic or hydraulic line, fibre or cable bundle can pass straight through it. The rings are mounted on an insulated sleeve that fits over or around the machine shaft, and the brush blocks sit outside them in a stationary housing. Power, signal and data circuits are combined in one unit, while the bore keeps the rotation axis available for mechanics or services. Bore sizes range from a few millimetres to hundreds of millimetres.
When engineers choose a through-bore slip ring
Engineers choose a through-bore design when the axis of rotation is already occupied, typically by a shaft, a rotary union or a cable that must stay continuous. It is the standard choice for indexing tables, wrapping machines and turntables built around a central column. The trade-off is that larger rings mean higher surface speed, more brush wear and more drag torque at the same rpm, and the unit is bigger than a capsule. Where axial length is the constraint rather than diameter, a pancake design may suit better.
How to specify the Morgan Advanced Materials Wind turbine generator slip ring assemblies
Send these with your enquiry and an engineer can confirm the right Wind turbine generator slip ring assemblies variant or an equivalent:
- Bore diameter and shaft tolerance (mm)
- Outer diameter and length limits (mm)
- Circuit count and current per circuit (A)
- Working voltage and any high-voltage isolation (V)
- Speed, continuous and peak (rpm)
- Data or bus protocols to pass, such as Ethernet, CAN or PROFINET
- Sealing (IP code), temperature (°C) and mounting method
Common mistakes to avoid
- Sizing the bore to the shaft only, with no allowance for a rotary union or cables that must also pass
- Mounting the rotor hard on a shaft with radial runout and a separate stator fixing, so the unit is forced to align two axes
- Forgetting that surface speed rises with diameter, so the rated rpm is lower for larger bores
- Not stating which circuits need screening or twisted pairs for encoder and fieldbus signals
Morgan Advanced Materials Wind turbine generator slip ring assemblies: frequently asked questions
Can you help replace Morgan Advanced Materials Wind turbine generator slip ring assemblies or source the original?

What is the Morgan Advanced Materials Wind turbine generator slip ring assemblies?
Complete brush, rocker, holder and slip ring systems for wind turbine generators from 850 kW to 10 MW, 144 to 450 mm in diameter, with stainless steel or bronze rings in moulded or built-up designs, for new turbines and retrofits. Published series figures include outer diameter 144 mm, outer diameter 450 mm, power 850,000 W, power 10,000,000 W. It is made by Morgan Advanced Materials plc; Specify Motion can help source it or propose an equivalent.
Who makes the Morgan Advanced Materials Wind turbine generator slip ring assemblies?
The Morgan Advanced Materials Wind turbine generator slip ring assemblies is made by Morgan Advanced Materials (Morgan Advanced Materials plc) and is listed here for engineers comparing options. Specify Motion is not affiliated with Morgan Advanced Materials plc; brand names are used only to identify the product.
What is the outer diameter of the Morgan Advanced Materials Wind turbine generator slip ring assemblies?
The published series minimum outer diameter is 144 mm. Individual models and sizes in the Wind turbine generator slip ring assemblies 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 Morgan Advanced Materials Wind turbine generator slip ring assemblies?
We can assess suitable replacement options. On published figures, Motion Control Products ER Series Through Bore Slip Ring is options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
How do I choose the bore size for a through-bore slip ring?
Start with the shaft diameter and its tolerance, then add anything else that must pass through the centre, such as hoses, a rotary union stem or a fibre. Allow clearance for assembly and for the insulating sleeve. Larger bores raise surface speed, cost and drag torque, so pick the smallest bore that genuinely clears what has to pass through.
Can a through-bore slip ring carry Ethernet as well as power?
Yes. Many through-bore units combine power rings with signal rings designed for industrial Ethernet, using controlled impedance, twisted-pair routing and screening between groups. State the protocol and speed, typically 100 Mbit/s or gigabit, so the supplier can allocate suitable rings and keep them away from motor power. For very high data rates, a contactless or fibre channel may be added.
